Built from vanadium high speed steel and finished with a TiN (titanium nitride) coating, it offers extended tool life and reduced friction at the cutting edge. The 130-degree, 4-facet point geometry with web thinning promotes accurate hole entry and reduces thrust force. At 46.00 mm overall length with a 14.00 mm flute length, this compact stub-style bit is suited for CNC machining centers, drill presses, and manual operations where rigidity and precision matter.\u003c\/p\u003e\u003cp\u003eThis drill bit is used in production machining and maintenance environments where shorter, stiffer tooling is preferred over jobber-length bits. The 2.55 mm diameter and straight cylindrical shank make it compatible with standard collet chucks and drill chucks. Its regular spiral flute geometry handles chip evacuation in a range of materials including mild steel, stainless, and aluminum alloys. The 5xD flute-to-diameter ratio keeps the tool body rigid in short-reach applications. This bit is typically run by machinists, tool and die technicians, and maintenance mechanics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting edge life compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003e130-degree 4-facet point with web thinning for accurate hole entry and lower thrust\u003c\/li\u003e\n\u003cli\u003eVanadium high speed steel construction for durability in ferrous and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides increased rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for positive chip removal\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard collet and drill chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit suitable for use in standard drill chucks and collet systems accepting a 3.00 mm straight shank.

Secure the shank fully in the chuck or collet before operation and verify runout before beginning a cut. Always follow machine manufacturer guidelines for spindle speed and feed rate for the workpiece material. Eye protection and appropriate chip guarding are required during use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.55 mm (0.1004 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 46.00 mm (1.811 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: 4 Facet\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\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\u003eTool Material\u003c\/strong\u003e: Vanadium 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Non-Ferrous\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: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 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: 8595255\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746879734066,"sku":"8595255","price":37.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2882ef1fe598206ec666eb082076d472_ddb69251-549f-4d68-80d0-ed73e3124889.jpg?v=1788874283","url":"https:\/\/voomisupply.com\/products\/osg-8595255-screw-machine-drill-bit-2-55mm-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
