Built from cobalt high speed steel with a titanium nitride (TiN) coating, this bit handles demanding materials that standard HSS tooling struggles with. It measures 23\/64 inches (0.3594 inches decimal) in diameter with a 3-9\/16 inch overall length and a 130-degree split point for fast penetration and reduced walking. The shorter screw machine length body provides increased rigidity compared to jobber-length bits, making it well-suited for CNC machining centers, turret lathes, and drill presses.\u003c\/p\u003e\u003cp\u003eThis bit is intended for professional machinists and tooling technicians working in production and job-shop environments. The cobalt HSS construction and TiN coating extend tool life when drilling hardened steel, alloy steel, and other ferrous metals. The straight cylindrical shank fits standard drill chucks without requiring collets or adapters. With a 3xD flute-to-diameter ratio and a 1-3\/4 inch flute length, it is optimized for shorter-reach, high-rigidity setups typical in screw machine and turret operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction resists heat and wear in steel and alloy steel drilling\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with R-thinned web for fast engagement and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eScrew machine length body (3-9\/16 inches OAL) delivers greater rigidity than jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with tapered web configuration for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank (0.375 inches diameter) fits standard three-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, CNC machining centers, turret lathes, and screw machines equipped with standard straight-shank drill chucks.

Secure the straight shank firmly in the chuck to the full grip depth before operation. Use appropriate cutting fluid or coolant for steel drilling to manage heat buildup, as this bit does not support through-coolant delivery. Inspect the cutting edges before each use and replace the bit if chipping or wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 23\/64 inches (0.3594 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 9.13 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-9\/16 inches (3.5433 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches (44 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: Steel, Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.095 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10359405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748344496434,"sku":"10359405","price":123.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e4ad1ed67bcade735ea9664a8980f20.jpg?v=1788892729","url":"https:\/\/voomisupply.com\/products\/osg-10359405-screw-machine-drill-bit-23-64-in-cobalt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
