Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. The 130-degree faceted point geometry promotes accurate entry and reduces walking on flat surfaces. With an overall length of 52 millimeters and a flute length of 20 millimeters, this short-length bit offers increased rigidity compared to jobber-length alternatives. It is suited for CNC machining centers, drill presses, and turret lathes where stub-length tooling is preferred. Machinists and toolroom technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis drill bit is appropriate for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length format makes it a practical choice for high-speed production environments where chatter and deflection must be minimized. The web-thinned, tapered web configuration reduces thrust requirements and improves chip evacuation. It fits standard straight-cylindrical shank tool holders with a 4.00 mm shank diameter, common in both manual and CNC setups. The 5xD flute-to-diameter ratio supports efficient chip clearance in moderately deep holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating extends tool life and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003e130-degree faceted point for accurate positioning and clean entry on metal workpieces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces axial thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides added rigidity versus standard jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute geometry compatible with conventional drill press and CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.018 mm ensures consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in straight-cylindrical shank tool holders; compatible with steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces as specified by the manufacturer for OSG Series 1100.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove this bit with the spindle fully stopped and the machine isolated from power. Secure the shank fully in the chuck or collet to the recommended grip depth before operation. Verify spindle speed and feed rate against manufacturer recommendations for the specific workpiece material. Inspect the cutting edge and TiN coating for wear or chipping before each use; a damaged edge should not be run in production.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.56 mm (0.1402 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 52 mm (2.0472 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 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\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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 -0.018 mm\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: 0.01 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: 8595356\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738656014642,"sku":"8595356","price":47.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2882ef1fe598206ec666eb082076d472_7ae0bd88-e11e-40ec-8164-11808cfd66a9.jpg?v=1788802402","url":"https:\/\/voomisupply.com\/products\/osg-8595356-screw-machine-drill-bit-3-56-mm-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
