General purpose high speed steel Unibit® step drill bits are perfect for use in mild steel, copper, brass, aluminum, plexiglass, wood, and laminate. Our titanium nitride coated (TiN) bits resist heat and friction, which extends the life of the cutting edge six times longer than standard step drills. And, our cobalt step drill bits are engineered with m35 cobalt steel for maximum life when drilling in the toughest steel, including stainless steel. Most Unibit® step drills are designed with a SpeedPoint® tip that guarantees fast starts. Theyre manufactured with a single flute cutting edge that drills multiple sizes of true, round holes with precise step control. Plus, the hole sizes are permanently laser etched on the inside of the flute, so they can be easily identified throughout the life of the bit.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003ePACKAGE DESCRIPTION\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003ePackage Quantity: 1\/PK\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAPPLICATION\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eFor drilling holes into thin materials\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli class=\"is-root\"\u003eSingle flute cutting edge for greater control through steps\u003c\/li\u003e \u003cli class=\"is-root\"\u003e3 flatted shank prevents slipping in drill chuck\u003c\/li\u003e \u003cli class=\"is-root\"\u003ePatented single flute cutting edge gives the user a true round hole every time\u003c\/li\u003e \u003cli class=\"is-root\"\u003eGeometry of single flute cutting edge drills true, round holes and provides maximum step control\u003c\/li\u003e \u003cli class=\"is-root\"\u003eLaser etched sizes inside flute for easy and permanent hole size identification\u003c\/li\u003e \u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\u003ctable border=\"0\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eType: \u003c\/td\u003e \u003ctd\u003eHole Enlarging\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDrill Diameter Measurement System: \u003c\/td\u003e \u003ctd\u003eImperial\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eLetter\/Wire Size: \u003c\/td\u003e \u003ctd\u003e#21\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMinimum Hole Diameter: \u003c\/td\u003e \u003ctd\u003e13\/16\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMaximum Hole Diameter: \u003c\/td\u003e \u003ctd\u003e1-3\/8\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eNumber of Steps: \u003c\/td\u003e \u003ctd\u003e10\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eStep Depth: \u003c\/td\u003e \u003ctd\u003e1\/8\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eNumber of Hole Sizes: \u003c\/td\u003e \u003ctd\u003e10\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eNumber of Flutes: \u003c\/td\u003e \u003ctd\u003e1\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eShank Size: \u003c\/td\u003e \u003ctd\u003e7\/16\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eShank Type: \u003c\/td\u003e \u003ctd\u003e3-Flat\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePoint Type: \u003c\/td\u003e \u003ctd\u003eSpeedPoint®\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCutting Edge Material: \u003c\/td\u003e \u003ctd\u003eHSS\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMaterial: \u003c\/td\u003e \u003ctd\u003eHSS\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFinish: \u003c\/td\u003e \u003ctd\u003eBright\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eApplicable Materials: \u003c\/td\u003e \u003ctd\u003eAluminum, Brass, Copper, Laminates, Plastic and Stainless Steel\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e\n                \u003c!-- snippet location product_description --\u003e","brand":"Irwin Vise-Grip","offers":[{"title":"Default Title","offer_id":48296557281579,"sku":"10221","price":93.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0481\/1833\/3590\/files\/Irwin_Unibit_10221__96749.1689743703.jpg?v=1711595930","url":"https:\/\/www.urbanindustrialproducts.com\/products\/irwin-10221-unibit-21-hss-10-step-drill-bit","provider":"UrbanIndustrialProducts.com","version":"1.0","type":"link"}
