Built from vanadium high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced heat buildup during drilling. The bit measures 0.3386 inches (8.60 mm) in diameter with a 3.5433-inch overall length and a 120-degree, 4-facet point that improves centering accuracy and reduces walking on entry. The web-thinned, parallel web configuration lowers thrust requirements. This bit is suited for machinists, tool and die professionals, and maintenance technicians working with tight-tolerance bore applications.\u003c\/p\u003e\n\u003cp\u003eThe OSG 61586 is rated for use on aluminum, carbon steel, high nickel alloy, stainless steel, and titanium workpieces. Its screw machine length — shorter than jobber length — improves rigidity and reduces deflection in drill press, CNC, and turret lathe setups. The straight cylindrical shank seats in standard drill chucks and collet holders with a 0.3937-inch shank diameter. It is well suited for production environments where tool consistency and hole quality are critical across multiple workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting life compared to uncoated HSS\u003c\/li\u003e\n  \u003cli\u003eVanadium high speed steel substrate handles interrupted cuts and hard alloys\u003c\/li\u003e\n  \u003cli\u003e120-degree, 4-facet point geometry improves self-centering and reduces thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web lowers axial cutting forces\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body increases rigidity over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for drilling aluminum, carbon steel, high nickel alloy, stainless steel, and titanium.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Apply cutting fluid or coolant appropriate to the workpiece material to manage heat, as this bit does not support through-coolant delivery. Confirm shank seating depth and runout before beginning production cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3386 inches (8.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5433 inches (90.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 40.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: 4 Facet\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\u003eTool Material\u003c\/strong\u003e: Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel 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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Aluminum, Carbon Steel, High Nickel Alloy, Stainless Steel, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 61586\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733712601394,"sku":"61586","price":79.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68ac15d5db1d746e157973e3c012395b.jpg?v=1788758686","url":"https:\/\/voomisupply.com\/products\/osg-61586-screw-machine-drill-bit-0-3386-in-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
