Built from XPM high-speed steel with a V coating, it delivers increased wear resistance and longer tool life compared to standard HSS bits. The 130-degree split point reduces walking and allows immediate penetration without a center punch. With an overall length of 2.68 inches and a straight-cylindrical shank diameter of 0.2362 inches, this short-length bit is designed for rigid setups in drill presses, CNC machines, and screw machine operations where stub rigidity reduces deflection and improves hole accuracy.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling in steel, alloy steel, cast iron, and nickel alloys. Its screw machine length profile makes it a practical choice for tight-clearance drilling stations, turret lathes, and automatic screw machines where a standard-length bit would lack the required rigidity. It is also used in manual and CNC drill press operations where controlled chip evacuation and consistent hole tolerance are priorities. The 3xD flute-to-diameter ratio supports efficient chip removal in short-hole applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eXPM high-performance high-speed steel construction for extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eV coating increases surface hardness and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003e130-degree standard point with R-thinned web reduces thrust and eliminates drill walk\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eScrew machine length (3xD) provides maximum rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with tapered web for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling in steel, alloy steel, cast iron, and nickel alloy workpieces.

Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always set spindle speed and feed rate appropriate to the workpiece material and bit diameter before engaging the cut. Inspect the cutting edges and coating for wear or chipping before each use and replace the bit if the point geometry is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 11\/64 inches (4.37 mm \/ 0.1719 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: XPM High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: V Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.68 inches (68 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, R-Thinned\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 (3xD)\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 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Nickel Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 8608437\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754530832690,"sku":"8608437","price":75.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/241f39173ff81004d2dc41c4b9916a96.jpg?v=1788946358","url":"https:\/\/voomisupply.com\/products\/osg-8608437-screw-machine-drill-bit-11-64-inch-xpm","provider":"Voomi Supply","version":"1.0","type":"link"}
