Manufactured from HSS-CO 8% cobalt alloy (M42 grade), it delivers higher heat resistance and edge retention than standard HSS tooling. The 3 mm diameter bit features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. A parabolic flute geometry promotes fast chip evacuation, keeping the cutting edge clear during deep-hole drilling. Black oxide coating provides corrosion resistance and mild lubricity. Overall length is 100 mm with a 2.756-inch flute length, and the straight cylindrical shank seats directly in standard drill chucks.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for machine shop, fabrication, and maintenance applications requiring tight tolerances and consistent performance across a wide range of materials. The web-thinned, tapered web configuration reduces thrust requirements when drilling harder stock. It is appropriate for use in CNC drilling centers, drill presses, and hand-held power tools where a 3 mm straight-shank bit fits the chuck. Licensed machinists, tool-and-die workers, pipefitters, and industrial maintenance technicians are the primary users. Diameter tolerance is held to +0.0000 to -0.0005 inches for close-tolerance hole applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHSS-CO 8% cobalt (M42) construction for superior heat resistance and wear life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers and reduces thrust load at entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry for aggressive chip evacuation during deep drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating resists corrosion and reduces friction\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel.

Secure the straight shank firmly in the drill chuck and verify concentricity before starting the cut. Apply appropriate cutting fluid when drilling stainless steel, tool steel, or nickel alloys to maintain edge life. Follow shop safety protocols and applicable OSHA machine-guarding requirements during setup and operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3 mm (0.1181 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.756 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3 mm (0.1181 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3386 inches (34 mm)\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\u003eTool Material\u003c\/strong\u003e: HSS-CO 8% (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 340, DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: C16808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51689752854834,"sku":"C16808","price":57.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/314291eb4ffc1e9afba9865633e46c7a_950498df-6913-444e-9f49-56c7188f7913.jpg?v=1788263846","url":"https:\/\/voomisupply.com\/products\/cleveland-c16808-3mm-cobalt-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
