Built from M42 cobalt high-speed steel and coated with TiAlN for extended tool life, this 5\/16-inch diameter bit features a 135-degree split point that reduces walking and lowers thrust force on entry. The parabolic flute geometry promotes aggressive chip evacuation, making it well suited for deep-hole drilling in hard or abrasive materials. Licensed machinists, maintenance mechanics, and trade professionals performing precision drilling on cast iron, stainless steel, and similar ferrous metals will find this bit a reliable production-grade choice.\u003c\/p\u003e\n\u003cp\u003eThe C16997 fits standard jobber-length drilling tasks in both handheld and machine-mounted applications. Its straight-cylindrical shank is compatible with standard drill chucks and toolholders. Primary workpiece materials include cast iron and stainless steel, making it appropriate for HVAC, plumbing, and general mechanical work where hardened or work-hardening alloys are encountered. The 4.5-inch overall length and 3-3\/16-inch flute length accommodate typical through-hole and moderate-depth drilling scenarios without requiring extensions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction provides heat resistance and hardness retention at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating reduces friction and extends cutting edge life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point minimizes walk-out and reduces required feed pressure at entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile improves chip evacuation for cleaner holes and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web maintains core strength while lowering cutting resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 standards for dimensional accuracy and performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit compatible with standard 3-jaw drill chucks and machine toolholders accepting a 5\/16-inch straight-cylindrical shank.

Power down the drill press or deenergize the tool before changing bits. Do not force the bit through the workpiece; allow the split point and feed rate to control cutting speed. Cutting fluid is recommended when drilling stainless steel to manage heat, though this bit does not have coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt (M42 Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless 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: -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2075A\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: C16997\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51691287413042,"sku":"C16997","price":55.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/623cbae05e0a5cc2d3a40d440b2a3831_aca818ba-73bb-4145-83af-39b94f9383c1.jpg?v=1788282741","url":"https:\/\/voomisupply.com\/products\/cleveland-c16997-cobalt-drill-bit-5-16-in-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
