Built from M42 cobalt high-speed steel with a gold oxide coating, it delivers strong heat and wear resistance under sustained cutting loads. The 135-degree split point reduces walking on initial contact and lowers required thrust force. A parabolic flute geometry promotes efficient chip evacuation, making it well-suited for deep-hole drilling in tough workpiece materials. The straight-cylindrical shank seats directly in standard three-jaw chucks without an adapter.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for professional metalworking and fabrication trades where tight tolerances and reliable performance in hard or abrasive materials are required. Primary workpiece materials include cast iron, non-ferrous metals, stainless steel, and carbon steel. With a 1-inch flute length and a 2-inch overall length, it fits close-quarters drilling situations common in production and maintenance environments. It runs right-hand cut and requires no coolant-through capability from the spindle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for extended tool life in stainless steel, cast iron, and hard alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and entry thrust on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design accelerates chip removal and reduces heat buildup in the cut zone\u003c\/li\u003e\n  \u003cli\u003eGold oxide finish provides lubricity and additional surface hardness\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration lowers cutting resistance at the tip\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks — no bushing required\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to -0.0005 to 0.0000 inches for consistent, accurate hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting a 0.0670-inch straight-cylindrical shank.

Meets ASME B94.11M and DIN 338 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck and verify runout before starting the cut. Match spindle speed to the workpiece material and bit diameter — cobalt bits tolerate higher speeds than standard HSS but still require appropriate feeds to avoid tip overheating. When drilling stainless steel or hardened alloys, use a cutting fluid to extend tool life. Inspect the split point for chipping between uses; a damaged tip reduces hole accuracy and increases the risk of bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2075\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338\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: C16553\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700417364274,"sku":"C16553","price":17.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af56549fd77705b85ec1bd925bd937bd.jpg?v=1788390084","url":"https:\/\/voomisupply.com\/products\/cleveland-c16553-jobber-drill-bit-wire-51-cobalt-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
