Sized at 0.358 inches (Letter T) in diameter with a 135-degree split point, it delivers fast starts without a center punch and reduces thrust when drilling tough stock. The M42 cobalt alloy construction resists heat buildup, making it a reliable choice for professionals who push bits hard in production or maintenance environments. It is right-hand cut with a regular spiral flute and a straight-cylindrical shank, ready for use in standard drill chucks and screw machine setups.\u003c\/p\u003e\u003cp\u003eThis bit is built for machinists, maintenance technicians, and metalworking tradespeople working with hard ferrous and non-ferrous materials. The screw machine length format — shorter than jobber length — provides added rigidity and reduced deflection in turret lathes, screw machines, and drill presses. It suits production drilling applications where repeatability and bit life in hard stock are priorities. The 2.5xD flute-to-diameter ratio supports chip evacuation in short, controlled cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt alloy construction handles hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point starts on contact without center punching and reduces axial thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration improves cutting efficiency and chip clearance\u003c\/li\u003e\n\u003cli\u003eScrew machine length body adds rigidity and limits deflection compared to jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 2.5xD flute ratio supports chip evacuation in short-stroke drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length cobalt drill bit for use in drill presses, turret lathes, CNC screw machines, and hand-held drilling equipment accepting a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or maintenance technician familiar with metalworking equipment and safe drilling practices. Secure the workpiece before operation and confirm the chuck or collet is properly tightened to prevent shank slippage. Avoid running cobalt bits dry on hard materials — use appropriate cutting fluid to extend bit life and prevent heat damage to the cutting edge. Inspect the split point for damage before each use; a chipped or deformed point will affect hole location accuracy and increase thrust.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.358 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: T\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 Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: M42 Cobalt\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: 3.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.75 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, Web-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M42CO\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: 0.083 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: 5996532\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694741193010,"sku":"5996532","price":29.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/691739fe851d894f4ec47cb5cae18c43_cebf724f-bf65-431f-a899-f9775555acb9.jpg?v=1788327904","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996532-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
