Built from XPM high-speed steel with a V-coating finish, it features a 130-degree split-point (R-Thinned) tip that self-centers on entry and reduces thrust force. The straight-cylindrical shank measures 8 millimeters in diameter, and the overall length is 75 millimeters with a 31-millimeter flute length. The 2-flute, regular-spiral geometry promotes efficient chip evacuation in both through and blind-hole applications. Licensed machinists, tool-and-die techs, and maintenance professionals working on steel and alloy components are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in steel, alloy steel, cast iron, and nickel alloys, covering ISO material codes P, K, S, and H. Typical applications include blind-hole drilling, cross-hole operations, pilot drilling, and self-centering entry cuts. The tapered web configuration and R-Thinned point reduce walking on hard surfaces without requiring a center punch. It is sold individually and fits standard drill chucks and CNC tool holders accepting a straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eXPM high-speed steel construction with V-coating for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e130-degree R-Thinned split point self-centers on contact and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral geometry supports efficient chip evacuation in blind and cross-hole drilling\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds rigidity while maintaining cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and CNC tool holders\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement — suitable for dry or external coolant setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, cast iron, and nickel alloy workpieces.

Secure the straight-cylindrical shank fully in the chuck to the correct depth before engaging the spindle. Inspect the cutting edges and coating for wear or chipping before each use — a damaged tip will compromise hole tolerances and can break under load. Follow shop safety protocols and applicable machine guarding requirements when operating rotating tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches \/ 6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 31 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: XPM High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: V\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Nickel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering, Pilot Drilling\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: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 8608635\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736814387506,"sku":"8608635","price":71.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/208eda2cb2259917ce99375544f7ed0d.jpg?v=1788780674","url":"https:\/\/voomisupply.com\/products\/osg-8608635-jobber-length-drill-bit-1-4-inch-xpm","provider":"Voomi Supply","version":"1.0","type":"link"}
