Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction compared to uncoated bits. The bit measures 0.173 inches (wire size 17) in diameter with a 120-degree faceted point angle and a fast spiral flute geometry. Overall length is approximately 2.677 inches (68 mm) with a flute length of approximately 0.945 inches (24 mm). The straight-cylindrical shank measures approximately 0.236 inches (6 mm) in diameter. This bit is suited for machinists, toolroom technicians, and production drilling operators working with tight-tolerance applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length format  -  shorter than a jobber bit  -  provides added rigidity and accuracy in drill press, CNC, and manual machine tool setups. Web-thinned construction with a parallel web configuration reduces thrust force at the point, which is especially useful when working with harder alloys or when hole-start precision matters. It is sold individually and is appropriate for production shops and toolrooms requiring consistent, repeatable results.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiN coating extends cutting life and reduces heat buildup during drilling\u003c\/li\u003e\n  \u003cli\u003e120-degree faceted point angle for clean entry on steel and aluminum\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces drilling thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides greater rigidity than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, CNC machining centers, and manual machine tools accepting a straight-cylindrical shank.

Secure the shank fully in a compatible chuck before operation and confirm the bit is centered and locked before starting the spindle. Always wear appropriate eye protection and follow the machine manufacturer's speed and feed recommendations for the workpiece material. Do not exceed the bit's rated operating parameters or use the bit for hand-drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 17\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1730 inches\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: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.945 inches (24 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.677 inches (68 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.236 inches (6 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 8595439\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739877867826,"sku":"8595439","price":54.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0b1513757be27a22b44356ff2c4eaab.jpg?v=1788819958","url":"https:\/\/voomisupply.com\/products\/osg-8595439-screw-machine-drill-bit-0-173-in-wire-17-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
