Built to Series M40CO standards, this bit features a 135-degree split point for fast penetration and reduced walking, a web-thinned tapered web for lower thrust requirements, and a right-hand spiral flute for efficient chip evacuation. At 0.2812 inches (9\/32 inch) in diameter, it is sized for precision hole work in metals including stainless steel, tool steel, and other hard alloys. Licensed machinists, tool and die workers, and maintenance mechanics commonly use this bit in production and maintenance drilling applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in screw machine operations, CNC drilling, and bench drill press work where a shorter flute length and stubby overall length improve rigidity and reduce deflection. The straight-cylindrical shank seats securely in standard drill chucks and quick-change holders. Its cobalt construction and M40CO material grade make it a reliable choice when high-speed steel bits wear prematurely on hard or work-hardening materials. The 2.5xD flute-to-diameter ratio supports chip clearance in shorter hole depths typical of screw machine work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt M40CO construction for drilling hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces bit walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web decreases drilling resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine length provides added rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and quick-change tooling\u003c\/li\u003e\n\u003cli\u003eMeets ANSI specification standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production-use drill bit for applications requiring a 9\/32 inch diameter screw machine length bit in the 0.2500 to 0.3000 inch drill bit size range, compatible with standard drill chucks and screw machine tooling setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove drill bits only after the machine spindle has come to a complete stop and the machine is powered down or locked out per applicable OSHA lockout\/tagout procedures. Ensure the straight-cylindrical shank is fully seated and the chuck is tightened securely before operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this bit does not support coolant-through delivery. Inspect the cutting edges and split point for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 9\/32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2812 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M40CO\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5996015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699825541426,"sku":"5996015","price":17.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fc5f6262074872d44705f45fbae1b7_d3c9561d-6701-410d-839e-49a185a03e60.jpg?v=1788381624","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996015-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
