Built from M42 high-performance cobalt steel, it delivers the heat resistance and edge retention needed for drilling hard and abrasive materials. The parabolic flute geometry accelerates chip evacuation and reduces heat buildup during deep drilling. At 5.125 inches overall length with a 3.750-inch flute length, this drill fits standard jobber-length applications in machine shops, fabrication, and maintenance environments. Right-hand cutting direction. Straight-cylindrical shank at 0.3970 inches diameter seats securely in standard drill chucks and collets.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance drilling in cast iron, non-ferrous metals, stainless steel, and carbon steel. The web-thinned, tapered web construction reduces thrust requirements at entry, making it practical for hand-held drilling operations as well as CNC and manual drill press setups. The TiN coating provides additional surface hardness and lubricity, extending tool life in interrupted cuts and abrasive workpieces. It is a common choice for sheet metal shops, HVAC fabricators, plumbing contractors, and industrial maintenance technicians working with hard or challenging materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and decreases thrust at entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast, efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTiN coating adds surface hardness and extends cutting life\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces drill pressure in hard materials\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 338 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling cast iron, non-ferrous metals, stainless steel, and carbon steel; fits standard drill chucks and collets accepting a 0.3970-inch straight-cylindrical shank.

Secure the shank fully in the chuck or collet before operation and confirm concentricity. Use appropriate cutting fluid or coolant for the workpiece material to manage heat, particularly when drilling stainless steel. Do not exceed the rated cutting parameters for the machine and workpiece combination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3970 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.125 inches (130.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.750 inches (95.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3970 inches (10.08 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3752 inches (34.93 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\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\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: 0.024 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: C15672\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693275775282,"sku":"C15672","price":49.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f17a95740d972c69b0b9fa89d8b48f0_6e55c9c1-96f7-422a-bd5f-531c7bba1f2c.jpg?v=1788310035","url":"https:\/\/voomisupply.com\/products\/cleveland-c15672-cobalt-jobber-drill-bit-letter-x","provider":"Voomi Supply","version":"1.0","type":"link"}
