Built from M42 cobalt steel and finished with a Titanium Nitride (TiN) coating, this bit handles hardened steel, stainless, cast iron, and other abrasive metals that standard HSS bits cannot handle reliably. It measures 12 mm (0.4724 inches) in diameter with an overall length of 5.945 inches and a flute length of 3.976 inches. The 135-degree split point starts on contact without walking or requiring a center punch. Machinists, tool-and-die workers, and maintenance mechanics specify this bit for demanding production and repair applications.\u003c\/p\u003e\u003cp\u003eThe C16722 is suited for use in both CNC machining centers and manual drill presses. Its parabolic flute geometry improves chip evacuation and allows higher feed rates compared to standard spiral flutes, reducing heat buildup and extending tool life. The straight-cylindrical shank accepts standard drill chucks without adapters. This bit is a practical choice for fabrication shops, maintenance facilities, and industrial job sites drilling into steel, alloy steel, and similar hard materials where drill longevity and hole accuracy are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTitanium Nitride (TiN) coating reduces friction and extends cutting life\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering start without walking\u003c\/li\u003e\n\u003cli\u003eParabolic flute design improves chip clearance and allows higher feed rates\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust force required during drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks directly\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 specification for consistent jobber-length geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement or production-use drill bit for applications requiring a 12 mm or 0.4724-inch diameter hole in steel, stainless steel, cast iron, and similar hard materials.

Secure the shank fully in the chuck jaws before operation and verify chuck key is removed before starting the machine. Use appropriate cutting fluid or coolant for the material being drilled to preserve coating and edge life. Inspect the cutting edges for wear or chipping before each use and replace when the bit no longer starts cleanly or produces oversized holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.945 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.976 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C16722\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51692989612338,"sku":"C16722","price":89.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19bc05f89cf7d8a968f073e341cddb4c.jpg?v=1788305879","url":"https:\/\/voomisupply.com\/products\/cleveland-c16722-cobalt-drill-bit-12mm-tin-coated","provider":"Voomi Supply","version":"1.0","type":"link"}
