Built from powdered metal (XPM) with a TiCN V-coating, it delivers extended tool life and reduced heat buildup when cutting through steel, cast iron, high-temperature alloys, and hardened materials. The 130-degree split point with R-thinned tip and X-thinned web reduces thrust force and improves centering without a pilot hole. At 0.85 mm in diameter and 38.00 mm overall length, this bit is designed for precision small-diameter work in production and maintenance environments. It is installed and operated by machinists, tool-and-die professionals, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit fits screw machine length applications where a shorter, stiffer tool reduces deflection and improves hole accuracy. It is suited for drilling steel, cast iron, high-temperature alloys, and hardened materials in both manual and CNC setups. The straight cylindrical shank measures 3.00 mm in diameter, making it compatible with standard collets and drill chucks in that size range. The regular spiral flute and tapered web configuration promote efficient chip evacuation in short-hole drilling scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePowdered metal (XPM) construction for high-performance cutting in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiCN V-coating reduces friction and extends tool life in ferrous and high-temp alloy applications\u003c\/li\u003e\n\u003cli\u003e130-degree drill point with R-thinned tip for self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eX-thinned web with tapered configuration lowers cutting resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine length (3xD flute ratio) provides rigidity and minimizes deflection in small-diameter drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for standard chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard collets and drill chucks accepting a 3.00 mm straight cylindrical shank.

Power down and lock out the machine before changing tooling. Use appropriate cutting fluid or coolant for the workpiece material, noting this bit does not support through-coolant delivery. Inspect the cutting edge and coating for wear or chipping before each use, especially when drilling hardened materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.85 mm (0.0335 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38.00 mm (1.4961 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.00 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\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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Powdered Metal (XPM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN V-Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: 1900\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, Cast Iron, High-Temp Alloy, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 8608085\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728057237810,"sku":"8608085","price":51.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb3bbc1959dc85e71fb4a12871360de2.jpg?v=1788687199","url":"https:\/\/voomisupply.com\/products\/osg-8608085-screw-machine-drill-bit-0-85-mm-130-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
