Unlike conventional step bits which top out at 4mm thickness, this cutter can power through materials up to **10mm thick**. Driven by four high-performance cutting edges and a patented \"Step Tip\" that eliminates pre-drilling, it drills up to **6x faster** while automatically deburring as you go. Coated with premium AlCrN for extreme heat resistance, this is the ultimate tool for heavy-duty onsite fabrication.\u003c\/p\u003e\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cp\u003e\u003cstrong\u003e10mm Cutting Depth:\u003c\/strong\u003e Engineered with extended step heights that allow you to drill through thick workpieces (up to 10mm), unlike standard step drills which are limited to thin sheet metal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e6x Faster Drilling:\u003c\/strong\u003e Features four high-performance cutting edges instead of the standard two, allowing the bit to remove material rapidly with significantly less feed pressure required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePatented Step Tip: \u003c\/strong\u003eThe unique tip geometry bites instantly into the material, completely eliminating the need to centre punch or drill a pilot hole, even on curved surfaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAlCrN Multi-Layer Coating: \u003c\/strong\u003eCoated with Aluminium Chromium Nitride (AlCrN) to provide superior thermal stability and wear resistance, ensuring the cutting edges stay sharp even when drilling stainless steel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3-Flat Shank:\u003c\/strong\u003e Designed with a 3-flat shank that locks securely into the chuck jaws, ensuring optimal power transmission and preventing the bit from spinning under high torque.\u003c\/p\u003e\n\u003ch6\u003eAvailable Models:\u003c\/h6\u003e\n\u003ch5\u003e\u003cstrong\u003e4 - 12mm (9STM4-12DSD)\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eSteps:\u003c\/strong\u003e 8 (4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 11.0, 12.0mm)\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003e8 - 20mm (9STM8-20DSD)\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eSteps:\u003c\/strong\u003e 7 (8.0, 10.0, 12.0, 14.0, 16.0, 18.0, 20.0mm)\u003c\/p\u003e\n\u003ch5\u003e\n\u003cstrong\u003e9 - 19mm (9STM9-19DSD) \u003c\/strong\u003e\u003cstrong\u003eCable Gland Sizing\u003c\/strong\u003e\n\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eSteps:\u003c\/strong\u003e 6 (9.0, 11.0, 13.0, 15.0, 17.0, 19.0mm)\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003e3.3 - 10.2mm (9STM3.3-10.2DSD) - Tapping Drill Sizes\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eSteps:\u003c\/strong\u003e 6 (3.3, 4.2, 5.0, 6.8, 8.5, 10.2mm)\u003cbr\u003e\u003cem\u003ePerfect for pre-drilling holes for M4 to M12 taps.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e The use of quality cutting fluid is \u003cstrong\u003emandatory\u003c\/strong\u003e when drilling metals to prevent heat buildup and maximize tool life.\u003c\/p\u003e","brand":"Onsite+","offers":[{"title":"3.3 - 10.2mm","offer_id":51873178648852,"sku":"9STM4-M12DSD","price":99.0,"currency_code":"AUD","in_stock":true},{"title":"4-12mm","offer_id":51369623879956,"sku":"9STM4-12DSD","price":129.0,"currency_code":"AUD","in_stock":true},{"title":"8-20mm","offer_id":51369623912724,"sku":"9STM8-20DSD","price":149.0,"currency_code":"AUD","in_stock":true},{"title":"9-19mm","offer_id":51369623945492,"sku":"9STM9-19DSD","price":169.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/3986\/8436\/files\/9STM4-12DSD_2.jpg?v=1763317780"},{"product_id":"alpha-onsite-combination-drill-tap-drill-set","title":"Alpha Onsite+ Combination Drill \u0026 Tap Drill Set","description":"\u003ch5\u003eAlpha Onsite+ Step Tip Drill \u0026amp; Tap Sets (SM7DTST \/ SM17DTST)\u003c\/h5\u003e\n\u003cp\u003eThe Alpha Onsite+ \"Step Tip\" range revolutionizes drilling and tapping by solving the most common frustration with combination bits: jamming.
