Capable of creating nine distinct hole sizes with a single bit, it eliminates the need to constantly change drill bits or carry a bulky index set. The spiral flute geometry offers a significant advantage over standard straight flutes, providing smoother cutting action, reduced vibration, and superior chip evacuation, resulting in a cleaner, more precise finish on sheet steel, non-ferrous metals, and plastics.\u003c\/p\u003e\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cp\u003e\u003cstrong\u003eSpiral Flute Design:\u003c\/strong\u003e The twisted flute geometry ejects chips more efficiently than straight flutes, reducing cutting resistance and vibration for a smoother, quieter drilling experience.\u003cbr\u003e\u003cstrong\u003eTitanium Nitride (TiN) Coating:\u003c\/strong\u003e Coated with a hard ceramic TiN layer that significantly reduces surface friction and heat buildup, extending the lifespan of the cutting edge and allowing for faster drilling speeds.\u003cbr\u003e\u003cstrong\u003eDrills \u0026amp; Deburrs:\u003c\/strong\u003e Designed to perform two processes in one operation; as the bit advances to the next step, it automatically deburrs the top edge of the previous hole, leaving a safe, clean finish without manual cleanup.\u003cbr\u003e\u003cstrong\u003e3-Flat Shank:\u003c\/strong\u003e Features three ground flats on the shank that lock securely into the drill chuck jaws, ensuring maximum torque transmission and preventing the bit from spinning under load.\u003cbr\u003e\u003cstrong\u003eSelf-Starting Split Point:\u003c\/strong\u003e The precision split point bites into the material immediately, eliminating the need for a pilot hole and preventing the bit from wandering across the workpiece.\u003c\/p\u003e\n\u003ch6\u003eSpecifications:\u003c\/h6\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e 9STSFM4-12S\u003cbr\u003e\u003cstrong\u003eRange:\u003c\/strong\u003e 4mm - 12mm\u003cbr\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e Premium M2 HSS\u003cbr\u003e\u003cstrong\u003eCoating:\u003c\/strong\u003e Titanium Nitride (TiN)\u003cbr\u003e\u003cstrong\u003eShank:\u003c\/strong\u003e 6.0mm (3-Flat)\u003cbr\u003e\u003cstrong\u003eSteps:\u003c\/strong\u003e 9 Steps\u003c\/p\u003e\n\u003ch6\u003eStep Sizes:\u003c\/h6\u003e\n\u003cp\u003e4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e The use of quality cutting fluid is \u003cstrong\u003emandatory\u003c\/strong\u003e when using this step drill to prevent heat buildup and maximize tool life.\u003c\/p\u003e","brand":"Alpha","offers":[{"title":"Default Title","offer_id":51369626894612,"sku":"9STSFM4-12S","price":65.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/3986\/8436\/files\/9STSFM4-12S.jpg?v=1759820871","url":"https:\/\/clbis.com.au\/products\/alpha-spiral-flute-step-drill","provider":"Cost Less Bolts | Industrial Supplies","version":"1.0","type":"link"}
