Built from high speed steel with a coated finish, this bit features a 120-degree faceted point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at entry. The straight-cylindrical shank measures 8.00 millimeters in diameter, and the overall length is 81.00 millimeters (approximately 3.19 inches). A two-flute spiral design with a regular spiral type delivers consistent chip clearing during through-hole and blind-hole operations. This bit is sold individually and suited for production drilling environments where tool consistency and dimensional accuracy matter.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length — shorter than jobber length — improves rigidity and reduces deflection in drill press, turret lathe, and CNC machining center setups. It is a strong fit for machine shops, maintenance facilities, and production lines where compact drill length and a 5xD flute-to-diameter ratio are preferred for controlled chip flow in tight spindle arrangements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.3051 inch (7.75 mm) cutting diameter with a tolerance of plus 0 to minus 0.022 mm\u003c\/li\u003e\n\u003cli\u003e120-degree faceted point angle with web-thinned tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for wear resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine length with 5xD flute ratio for improved rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral configuration for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut; coolant-through feature not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Secure the shank fully in a drill chuck or collet before operation and verify chuck key removal before powering the spindle. Always wear appropriate eye protection and follow the machine manufacturer speed and feed recommendations for the workpiece material. Inspect the cutting edge for chipping or wear before each use and replace the bit if the edge is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3051 inches (7.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 81.00 mm (approximately 3.19 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 37.00 mm (approximately 1.46 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\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: plus 0 to minus 0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\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: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 8595775\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730840125746,"sku":"8595775","price":88.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2882ef1fe598206ec666eb082076d472_569c09ed-c5bc-4eb2-8452-70dd2375a8e4.jpg?v=1788723683","url":"https:\/\/voomisupply.com\/products\/osg-8595775-screw-machine-drill-bit-0-3051-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
