Built from cobalt high speed steel with a titanium nitride coating, this bit handles steel and alloy steel with reduced heat buildup and extended tool life. The 130-degree split point geometry with R-thinned web reduces walking and lowers thrust requirements at entry. At 3-3\/8 inches overall length and 19\/64 inches (0.2969 inches) diameter, the stub-length body provides added rigidity compared to jobber-length bits, making it well-suited for drill press and CNC work where runout control matters. Licensed machinists, tool-and-die shops, and maintenance mechanics are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is sized for the 19\/64-inch diameter range and falls within the Series 1000 high-performance lineup. It is appropriate for drilling steel and alloy steel in production and job-shop environments. The straight-cylindrical shank at 0.375 inches diameter fits standard drill chucks and collet holders without modification. The 3xD flute-to-diameter ratio and 1-9\/16-inch flute length suit short, rigid setups such as screw machine turrets, CNC lathes, and vertical machining centers where stub-length tooling is specified. It is sold individually, making it practical for both replacement and first-time tooling builds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction for heat resistance in steel and alloy steel drilling\u003c\/li\u003e\n\u003cli\u003eTitanium nitride coating reduces friction and extends tool life in production use\u003c\/li\u003e\n\u003cli\u003e130-degree split point with R-thinned, tapered web for self-centering entry and lower thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body at 3-3\/8 inches OAL provides rigidity over jobber-length alternatives\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.375 inches diameter fits standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute regular spiral design for chip evacuation in through-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard drill chucks and collet holders accepting a 0.375-inch straight-cylindrical shank.

Secure the shank fully in the chuck or collet before operation and verify runout before production drilling. Always power down and lock out the machine before changing tooling. Do not exceed the recommended feed and speed ranges for the workpiece material and drill diameter as specified in the tooling manufacturer or shop reference guides.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 19\/64 inches (0.2969 inches \/ 7.54 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches (85.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-9\/16 inches (39.00 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\u003eDrill Point 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\/Finish\u003c\/strong\u003e: Titanium Nitride\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 10296905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754487808306,"sku":"10296905","price":80.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4f8db996dcc60ba717388db2bd1f166.jpg?v=1788945919","url":"https:\/\/voomisupply.com\/products\/osg-10296905-screw-machine-drill-bit-19-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
