By turning down the shank to 12.7mm, these bits allow your standard 13mm power drill to tackle holes up to 20mm in diameter. Powered by Alpha's patented \"Step Tip\" technology, these drills cut significantly smoother than traditional reduced-shank bits, virtually eliminating the violent \"grabbing\" or jamming that often occurs when breaking through metal plate.\u003c\/p\u003e\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cp\u003e\u003cstrong\u003e12.7mm Reduced Shank:\u003c\/strong\u003e The shank is turned down to fit standard 1\/2\" (12.7mm) drill chucks, instantly expanding the capacity of your existing power tools without requiring expensive machinery upgrades.\u003cbr\u003e\u003cstrong\u003e3-Flat Shank Profile:\u003c\/strong\u003e Features three ground flats on the shank that lock into the chuck jaws, ensuring maximum torque transmission and preventing the bit from spinning inside the drill under heavy load.\u003cbr\u003e\u003cstrong\u003ePatented Step Tip Design:\u003c\/strong\u003e The innovative stepped geometry acts as a built-in pilot drill, reducing heat buildup and eliminating the need to center punch, while ensuring the bit stays sharper up to 6x longer than standard HSS.\u003cbr\u003e\u003cstrong\u003eBlack Oxide Finish:\u003c\/strong\u003e Treated with a premium black oxide coating that enhances lubricant retention, helping to keep the bit cool and improving chip flow during deep drilling operations.\u003cbr\u003e\u003cstrong\u003eBurr-Free Performance:\u003c\/strong\u003e The 135° split point and step design shear the material cleanly rather than gouging it, resulting in precise, round holes that require minimal deburring.\u003c\/p\u003e\n\u003ch6\u003eSpecifications:\u003c\/h6\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e SM6STRTP-B\u003cbr\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e M2 High Speed Steel (HSS)\u003cbr\u003e\u003cstrong\u003eShank:\u003c\/strong\u003e 12.7mm Reduced with 3-Flats\u003cbr\u003e\u003cstrong\u003eTip Type:\u003c\/strong\u003e Step Tip (135° Split Point)\u003cbr\u003e\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Oxide \/ Gold Ferrous\u003cbr\u003e\u003cstrong\u003eCutting Depth:\u003c\/strong\u003e 3xD\u003c\/p\u003e\n\u003ch6\u003eContents:\u003c\/h6\u003e\n\u003cp\u003e6 x Reduced Shank Drills: 14.0mm, 15.0mm, 16.0mm, 18.0mm, 19.0mm, 20.0mm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e The use of cutting fluid (such as Alpha Liquid Gold) is \u003cstrong\u003emandatory\u003c\/strong\u003e with these large diameter drills to prevent heat buildup and maximize tool life.\u003c\/p\u003e","brand":"Onsite+","offers":[{"title":"Default Title","offer_id":51369625714964,"sku":"SM6STRTP-B","price":399.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/3986\/8436\/files\/SM6STRTP-B.jpg?v=1759830392"},{"product_id":"alpha-onsite-plus-step-tip-reduced-shank-drill-bit","title":"Alpha Onsite+ Step Tip Reduced Shank Drill Bit","description":"\u003ch5\u003eAlpha Onsite+ Step Tip Reduced Shank Drill Bit (14mm - 25mm)\u003c\/h5\u003e\n\u003cp\u003eDrill large, perfectly centred holes with ease using the Alpha Onsite+ Step Tip Drill.
