class=\"sm-lead\">\n    A hand-held rock drill and an air-leg rock drill use the same percussive principle, the same 6 bar air supply and often the same drill steels. They are still not interchangeable. The first drills downward with the operator&#8217;s weight behind it. The second sits on a pneumatic leg that pushes it into a vertical face, so it can drill horizontal and inclined holes that no one could hold by hand. This guide explains how to choose between them, with diagrams, specification tables, compressor sizing and the dust and vibration rules that apply on site. It uses Set Makina&#8217;s four pneumatic rock drills as the reference: the Y20 and Y24 hand-held drills and the YT24 and YT28 air-leg drills.\n  <\/p>\n\n  <div class=\"sm-takeaways\">\n    <div class=\"sm-tk-title\">Key Takeaways<\/div>\n    <ul>\n      <li>The <strong>direction of the hole<\/strong> decides the machine type: downward holes need a hand-held drill, horizontal and inclined holes need an air-leg drill.<\/li>\n      <li>An air-leg carries the weight of the drill and supplies the <strong>feed force<\/strong>. That is what makes face drilling in galleries and tunnels possible for one operator.<\/li>\n      <li>Air-leg drills deliver more impact energy (about 75\u201384 N\u00b7m against 39\u201355 N\u00b7m on the hand-held models) and use <strong>air and water flushing<\/strong>, which keeps silica dust down underground.<\/li>\n      <li>Air demand ranges from <strong>1.32 m\u00b3\/min (Y20) to 4.80 m\u00b3\/min (YT28)<\/strong> at 6 bar. Size the compressor for the machines that run together, plus about 20 % margin, and derate for altitude.<\/li>\n      <li>All four models drill <strong>32\u201345 mm holes<\/strong> with the same 22 \u00d7 108 mm shank. Above that diameter, you need a DTH hammer, not a bigger hand drill.<\/li>\n    <\/ul>\n  <\/div>\n\n  <div class=\"sm-cards\">\n    <a class=\"sm-card\" href=\"https:\/\/setmakina.com\/en\/products\/tiger-y20\/\">\n      <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/setmakina.com\/wp-content\/uploads\/2025\/06\/tiger-y20-pneumatic-hand-held-rock-drill-small-scale-quarry-mining-construction.webp?resize=400%2C400&#038;ssl=1\" alt=\"Y20 pneumatic hand-held rock drill\" width=\"400\" height=\"400\" loading=\"lazy\">\n      <span class=\"sm-card-tag\">Hand-held<\/span>\n      <span class=\"sm-card-name\">Y20<\/span>\n      <span class=\"sm-card-spec\">18 kg \u00b7 ~39 N\u00b7m \u00b7 1.32 m\u00b3\/min<\/span>\n      <span class=\"sm-card-go\">View specs \u2192<\/span>\n    <\/a>\n    <a class=\"sm-card\" href=\"https:\/\/setmakina.com\/en\/products\/tiger-y24\/\">\n      <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/setmakina.com\/wp-content\/uploads\/2025\/06\/tiger-y24-pneumatic-hand-held-rock-drill-small-scale-quarry-mining-construction.webp?resize=400%2C400&#038;ssl=1\" alt=\"Y24 pneumatic hand-held rock drill\" width=\"400\" height=\"400\" loading=\"lazy\">\n      <span class=\"sm-card-tag\">Hand-held<\/span>\n      <span class=\"sm-card-name\">Y24<\/span>\n      <span class=\"sm-card-spec\">24 kg \u00b7 ~55 N\u00b7m \u00b7 3.00 m\u00b3\/min<\/span>\n      <span class=\"sm-card-go\">View specs \u2192<\/span>\n    <\/a>\n    <a class=\"sm-card\" href=\"https:\/\/setmakina.com\/en\/products\/tiger-yt24\/\">\n      <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/setmakina.com\/wp-content\/uploads\/2025\/06\/tiger-yt24-air-leg-rock-drill-mining-tunneling-railway-construction.webp?resize=400%2C400&#038;ssl=1\" alt=\"YT24 pneumatic air-leg rock drill\" width=\"400\" height=\"400\" loading=\"lazy\">\n      <span class=\"sm-card-tag\">Air-leg<\/span>\n      <span class=\"sm-card-name\">YT24<\/span>\n      <span class=\"sm-card-spec\">24 kg \u00b7 ~75 N\u00b7m \u00b7 3.60 m\u00b3\/min<\/span>\n      <span class=\"sm-card-go\">View specs \u2192<\/span>\n    <\/a>\n    <a class=\"sm-card\" href=\"https:\/\/setmakina.com\/en\/products\/tiger-yt28\/\">\n      <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/setmakina.com\/wp-content\/uploads\/2025\/06\/tiger-yt28-air-leg-rock-drill-mining-tunneling-railway-construction.webp?resize=400%2C400&#038;ssl=1\" alt=\"YT28 pneumatic air-leg rock drill\" width=\"400\" height=\"400\" loading=\"lazy\">\n      <span class=\"sm-card-tag\">Air-leg<\/span>\n      <span class=\"sm-card-name\">YT28<\/span>\n      <span class=\"sm-card-spec\">26 kg \u00b7 ~84 N\u00b7m \u00b7 4.80 m\u00b3\/min<\/span>\n      <span class=\"sm-card-go\">View specs \u2192<\/span>\n    <\/a>\n  <\/div>\n\n  <h2><span class=\"sm-num\">01<\/span>Start with one question: which way does the hole point?<\/h2>\n\n  <p>\n    Most buyers compare weight, air consumption and price first. Those numbers matter, but they come second. The first question is geometric. If your holes go down into a bench, a block or the floor of a trench, a <strong>hand-held rock drill<\/strong> (also called a jackhammer or sinker drill) does the job, and gravity helps you. If your holes go into a vertical face, a tunnel heading or a gallery wall, you need a machine that can push sideways with steady force for the whole length of the hole. A person cannot do that for a full shift. An <strong>air-leg rock drill<\/strong> (often called a jackleg drill) can.\n  <\/p>\n\n  <div class=\"sm-diagram\">\n    <svg viewBox=\"0 0 760 300\" role=\"img\" aria-labelledby=\"smdTitle smdDesc\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n      <title id=\"smdTitle\">Hand-held rock drill versus air-leg rock drill<\/title>\n      <desc id=\"smdDesc\">Left: a hand-held drill drilling a vertical hole downward into a bench, with feed from the weight of drill and operator.

A piston driven by compressed air strikes the shank of the drill steel, and a ratchet mechanism turns the steel a few degrees between blows so the bit hits fresh rock. The feed force comes from the weight of the machine and the operator. Cuttings are blown out of the hole by air flushing through the centre of the drill steel.<\/p>\n      <p>On the Y24 the flushing is air only. The Y20 uses air flushing as standard, with a water connection available as an option on the TIGER version and included on the LIGER version.<\/p>\n    <\/div>\n  <\/div>\n\n  <div class=\"sm-factor\">\n    <div class=\"sm-factor-num\">2<\/div>\n    <div class=\"sm-factor-body\">\n      <h3>Air-leg rock drill<\/h3>\n      <p>The drill is mounted on a pneumatic telescopic leg. The operator sets the leg on the floor at an angle, and the leg extends as the hole advances, holding the drill up and pushing it into the face. The operator controls the feed from the drill&#8217;s grouped controls instead of carrying the load. When the leg reaches full stroke, it is retracted and repositioned.<\/p>\n      <p>The YT24 runs on the FT140BC or FT140BD air-leg and the YT28 on the FT160BC or FT160BD. Both can also be mounted on a rig, wagon or sled. Both have a water connection as standard and drill with air and water flushing.<\/p>\n    <\/div>\n  <\/div>\n\n  <p>Seeing both machines working makes the difference obvious:<\/p>\n\n  <div class=\"sm-videos\">\n    <div>\n      <div class=\"sm-video\"><iframe src=\"https:\/\/www.youtube-nocookie.com\/embed\/hQUogDR81JM\" title=\"Y24 hand-held rock drill in operation\" loading=\"lazy\" allow=\"accelerometer;

Second, every model ships with the <a href=\"https:\/\/setmakina.com\/en\/products\/tiger-fy200b-line-oiler\/\">FY200B in-line oiler<\/a>, which feeds rock drill oil into the air line and keeps the piston and valve lubricated during the shift.\n  <\/p>\n\n  <h3>What f8\u2013f18 means in practice<\/h3>\n  <p>\n    The Protodyakonov strength coefficient (f) is still the most common way to rate rock drills for rock hardness, especially in mining.

The <strong>Y20<\/strong> uses less than half the air of the Y24, which suits small quarries and modest compressors. The <strong>Y24<\/strong> is the production hand-held drill for daily work in hard rock. Between the air-leg drills, the <strong>YT24<\/strong> is lighter and uses less air, while the <strong>YT28<\/strong> is the heavier machine built for continuous face drilling.\n  <\/p>\n\n  <h2><span class=\"sm-num\">05<\/span>The compressor decides more than the drill<\/h2>\n\n  <p>\n    A pneumatic rock drill is only as strong as the air that reaches it. If the pressure at the drill falls below 6 bar, the blow weakens and penetration drops, and a slow drill costs more per metre than a fast one. The rule for sizing is simple: add the air consumption of every drill that works at the same time, then add about 20 % for hose losses, fitting leaks and the oiler. This margin is an engineering allowance, not a factory figure.\n  <\/p>\n\n  <div class=\"sm-table-wrap\">\n    <table>\n      <thead>\n        <tr><th>Model<\/th><th>Consumption at 6 bar<\/th><th>1 drill (+20 %)<\/th><th>2 drills (+20 %)<\/th><th>3 drills (+20 %)<\/th><\/tr>\n      <\/thead>\n      <tbody>\n        <tr><td>Y20<\/td><td>1.32 m\u00b3\/min<\/td><td>1.6 m\u00b3\/min (56 cfm)<\/td><td>3.2 m\u00b3\/min (112 cfm)<\/td><td>4.8 m\u00b3\/min (168 cfm)<\/td><\/tr>\n        <tr><td>Y24<\/td><td>3.00 m\u00b3\/min<\/td><td>3.6 m\u00b3\/min (127 cfm)<\/td><td>7.2 m\u00b3\/min (254 cfm)<\/td><td>10.8 m\u00b3\/min (381 cfm)<\/td><\/tr>\n        <tr><td>YT24<\/td><td>3.60 m\u00b3\/min<\/td><td>4.3 m\u00b3\/min (153 cfm)<\/td><td>8.6 m\u00b3\/min (305 cfm)<\/td><td>13.0 m\u00b3\/min (458 cfm)<\/td><\/tr>\n        <tr><td>YT28<\/td><td>4.80 m\u00b3\/min<\/td><td>5.8 m\u00b3\/min (203 cfm)<\/td><td>11.5 m\u00b3\/min (407 cfm)<\/td><td>17.3 m\u00b3\/min (610 cfm)<\/td><\/tr>\n      <\/tbody>\n    <\/table>\n  <\/div>\n  <p class=\"sm-caption\">1 m\u00b3\/min = 35.3 cfm. Figures are free air delivery the compressor must supply at 6 bar or more.<\/p>\n\n  <h3>Altitude reduces what your compressor delivers<\/h3>\n  <p>\n    Many quarries and mines in North Africa, the Middle East and Central Asia work well above sea level. Thinner air means a compressor takes in less mass of air per stroke, so its real output at altitude is lower than its sea-level rating. Atmospheric pressure falls quickly with height:\n  <\/p>\n\n  <div class=\"sm-table-wrap\">\n    <table>\n      <thead>\n        <tr><th>Site altitude<\/th><th>Atmospheric pressure (standard atmosphere)<\/th><th>Compared with sea level<\/th><\/tr>\n      <\/thead>\n      <tbody>\n        <tr><td>0 m<\/td><td>101.3 kPa<\/td><td>100 %<\/td><\/tr>\n        <tr><td>1,000 m<\/td><td>89.9 kPa<\/td><td>about 89 %<\/td><\/tr>\n        <tr><td>2,000 m<\/td><td>79.5 kPa<\/td><td>about 78 %<\/td><\/tr>\n        <tr><td>3,000 m<\/td><td>70.1 kPa<\/td><td>about 69 %<\/td><\/tr>\n      <\/tbody>\n    <\/table>\n  <\/div>\n\n  <p>\n    Check the altitude derating in your compressor&#8217;s data sheet, and add it on top of the 20 % margin. Distance matters too: all four drills connect through a 3\/4&#8243; air inlet and should work within about 100 m of the compressor. For longer runs, an <a href=\"https:\/\/setmakina.com\/en\/products\/tiger-air-receiver\/\">air receiver<\/a> placed near the drilling point keeps the pressure steady. Use a <a href=\"https:\/\/setmakina.com\/en\/products\/pneumatic-hose\/\">pneumatic hose<\/a> rated for the working pressure, and keep it as short as the site allows.\n  <\/p>\n\n  <div class=\"sm-callout sm-callout-warn\">\n    <p><strong>A practical example:<\/strong> three Y20 drills need about 4.8 m\u00b3\/min together. That is less than two Y24 drills (7.2 m\u00b3\/min). On a small site with holes of 45 mm or less, three light drills on one compressor can give more drilled metres per shift than two heavier ones on a bigger compressor.<\/p>\n  <\/div>\n\n  <h2><span class=\"sm-num\">06<\/span>Dust and vibration: the rules that shape the choice<\/h2>\n\n  <h3>Silica dust<\/h3>\n  <p>\n    Drilling granite, sandstone and other quartz-bearing rock releases respirable crystalline silica. In the European Union, Directive (EU) 2017\/2398 added work that generates respirable crystalline silica dust to the carcinogens directive, with a binding limit of 0.1 mg\/m\u00b3 [1]. In the United States, OSHA&#8217;s construction silica standard lists water delivery at the point of impact or dust collection as the control for jackhammers and hand-held drilling tools [2]. In practice, wet drilling is the simplest control. The YT24 and YT28 flush with water as standard, and the Y20 can take a water connection. The Y24 flushes with air only, so on dust-controlled sites it needs another control method or should be replaced by a wet model.\n  <\/p>\n\n  <h3>Hand-arm vibration<\/h3>\n  <p>\n    Every percussive hand tool transmits vibration to the operator&#8217;s hands and arms, and pneumatic rock drills are among the most demanding tools on a site. EU Directive 2002\/44\/EC sets a daily exposure action value of 2.5 m\/s\u00b2 and a limit value of 5 m\/s\u00b2 (A(8)) for hand-arm vibration [3]. In practice, exposure is managed with three measures used together: limit the drilling time per operator and rotate operators on long jobs, keep the drill well lubricated and correctly fed so it does not bounce on the rock, and give every operator anti-vibration gloves.\n  <\/p>\n\n  <h3>Which anti-vibration gloves work best<\/h3>\n  <p>\n    A 2025 study by the Department of Mining Engineering at \u00c7ukurova University compared 12 commercial anti-vibration gloves made of different materials, both on air-leg drill operators in three mines and in a laboratory test following ISO 10819 [4]. Gloves padded with <strong>chloroprene rubber<\/strong> gave the highest damping in both settings. Latex foam gave the lowest.\n  <\/p>\n\n  <div class=\"sm-table-wrap\">\n    <table>\n      <thead>\n        <tr><th>Glove padding material<\/th><th>Vibration damping in the mines<\/th><th>Vibration damping in the laboratory<\/th><\/tr>\n      <\/thead>\n      <tbody>\n        <tr><td>Chloroprene rubber (5\u20136 mm)<\/td><td>about 24 %<\/td><td>about 45 %<\/td><\/tr>\n        <tr><td>Polyurethane, SBR rubber, neoprene, gel foam, special pads<\/td><td>between the two<\/td><td>between the two<\/td><\/tr>\n        <tr><td>Latex foam coating (3 mm)<\/td><td>about 4 %<\/td><td>about 23 %<\/td><\/tr>\n      <\/tbody>\n    <\/table>\n  <\/div>\n  <p class=\"sm-caption\">Source: Erol, Applied Sciences, 2025 [4].

An air-leg rock drill is mounted on a pneumatic leg that supports the drill and pushes it into the face, so it can drill horizontal and inclined holes in tunnels, galleries and mines.<\/p>\n    <\/div>\n    <div class=\"sm-faq-item\">\n      <h3>Do anti-vibration gloves help when using a rock drill?<\/h3>\n      <p>Yes. In a 2025 field and laboratory study of 12 glove types used with air-leg rock drills, gloves padded with chloroprene rubber reduced hand-arm vibration exposure the most, by about 24 % in the mines and 45 % in the laboratory. Gloves should be combined with limits on drilling time per operator and good maintenance of the drill.<\/p>\n    <\/div>\n    <div class=\"sm-faq-item\">\n      <h3>Is a jackleg drill the same as an air-leg rock drill?<\/h3>\n      <p>Yes. Jackleg, air-leg and pusher-leg drill are names for the same type of machine: a pneumatic rock drill mounted on a telescopic pneumatic leg. The YT24 and YT28 are air-leg drills.<\/p>\n    <\/div>\n    <div class=\"sm-faq-item\">\n      <h3>Can a hand-held rock drill be fitted on an air-leg?<\/h3>\n      <p>Not in Set Makina&#8217;s range. The Y20 and Y24 are built for downward vertical drilling. For horizontal or angled holes, use the YT24 or YT28, which are designed to work on the FT140 and FT160 air-legs.<\/p>\n    <\/div>\n    <div class=\"sm-faq-item\">\n      <h3>What size compressor does an air-leg rock drill need?<\/h3>\n      <p>The YT24 uses 3.60 m\u00b3\/min and the YT28 4.80 m\u00b3\/min at 6 bar. With about 20 % margin for losses, plan roughly 4.3 m\u00b3\/min for one YT24 and 5.8 m\u00b3\/min for one YT28, more at altitude. Keep the drill within about 100 m of the compressor, or add an air receiver near the face.<\/p>\n    <\/div>\n    <div class=\"sm-faq-item\">\n      <h3>Can the same drill steels be used on all four models?<\/h3>\n      <p>Yes. The Y20, Y24, YT24 and YT28 all use a 22 \u00d7 108 mm shank, so the same integral drill steels and bits fit every machine in a mixed fleet.<\/p>\n    <\/div>\n    <div class=\"sm-faq-item\">\n      <h3>Which rock drill is best for a small quarry?<\/h3>\n      <p>For downward holes up to 45 mm, the Y20 is the most economical choice on air, and the Y24 is the better choice for daily production in hard rock. If the quarry also needs horizontal holes along the bench floor, add an air-leg drill for those.<\/p>\n    <\/div>\n  <\/div>\n\n  <div class=\"sm-cta\">\n    <h3>Not sure which drill fits your site?<\/h3>\n    <p>Tell us the hole direction, diameter, rock type, site altitude and the compressor you have.
