It features a 0.54 mm diameter (0.0213 decimal inch), a 150-degree faceted point, and a Titanium Nitride (TiN) coating over a High-Speed Steel body. The TiN coating increases surface hardness and reduces friction, extending tool life compared to uncoated HSS. The web-thinned, tapered web design reduces thrust and improves chip evacuation. At 38 mm overall length (approximately 1.496 inches), this stub-length bit provides rigidity and runout control for close-tolerance holes. It is installed by machinists, tool-and-die professionals, and precision fabricators.\u003c\/p\u003e\u003cp\u003eThe OSG 8595054 is designed for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials. The screw machine length format suits CNC machining centers, drill presses, and turret lathes where short, rigid tooling is required. With a 3.00 mm straight-cylindrical shank (0.1181 decimal inch), it fits standard collet chucks and drill chucks across a wide range of machines. The 5xD flute-to-diameter ratio and regular spiral geometry support chip clearing in short-depth holes typical of screw machine and production drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.54 mm diameter with tolerance of +0 to -0.014 mm for close-tolerance work\u003c\/li\u003e\n\u003cli\u003eTitanium Nitride (TiN) coating for improved wear resistance and reduced friction\u003c\/li\u003e\n\u003cli\u003e150-degree faceted point reduces walking and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers thrust and aids chip evacuation\u003c\/li\u003e\n\u003cli\u003eHigh-Speed Steel construction rated for high-performance drilling grades\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 3.00 mm shank fits standard collets and chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification screw machine length drill bit suitable for use in CNC machining centers, drill presses, and turret lathes accepting a 3.00 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists familiar with cutting tool setup and machine tool operation. Confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter before starting. Secure the shank fully in the collet or chuck and verify runout before cutting. Never exceed the rated speed or force the bit through the workpiece, as micro-diameter bits are susceptible to breakage under side load or excessive feed pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.54 mm (0.0213 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38.00 mm (1.496 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.50 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: 150 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\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: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eSeries\u003c\/strong\u003e: 1100\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, 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\u003eWeight\u003c\/strong\u003e: 0.005 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: 8595054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730083971378,"sku":"8595054","price":47.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0005731bdc401de563a4fd2b2c09e36.jpg?v=1788711488","url":"https:\/\/voomisupply.com\/products\/osg-8595054-screw-machine-drill-bit-0-54mm-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
