Built from vanadium high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in demanding drilling applications. The 1\/8 inch (3.18 mm) diameter bit features a 130-degree S-thinned point that improves self-centering performance and reduces the thrust force required to start a hole. At 68 mm overall length with a 36 mm flute length, it fits standard drill chucks and CNC toolholders with a straight cylindrical 4 mm shank. Manufactured under OSG Series 1600 to a diameter tolerance of +0 to -0.018 mm, this bit is suited for machinists, fabricators, and trade professionals who require consistent, repeatable results.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for drilling into steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. It handles blind holes, cross holes, through-hole drilling, and self-centering applications. The regular spiral flute geometry and right-hand cut make it compatible with standard drill presses, hand drills, and CNC machining centers. It is well suited for HVAC fabricators, plumbers, electricians, and metalworking shops that drill sheet metal, structural steel, and aluminum extrusions on a daily basis.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVanadium high speed steel construction for toughness in interrupted cuts and hard materials\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces heat buildup and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003e130-degree S-thinned point promotes self-centering and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eTapered web with regular spiral flute efficiently evacuates chips from blind and through holes\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without modification\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0 to -0.018 mm supports consistent hole sizing in precision work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials.

Power down and lock out the drill press or CNC spindle before changing bits. Use appropriate cutting fluid or coolant for stainless steel and harder steel alloys to manage heat; this bit does not support coolant-through delivery. Inspect the cutting edge and TiN coating condition before each use and replace if chipping or coating wear is visible.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches \/ 3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 68 mm (approximately 2.68 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36 mm (approximately 1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm (approximately 0.157 inches)\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: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: S-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium 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\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: 1600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 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: 8597318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727758655794,"sku":"8597318","price":43.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44770626c88e0371f5e7ff7ab0b6cdea.jpg?v=1788681844","url":"https:\/\/voomisupply.com\/products\/osg-8597318-jobber-drill-bit-1-8-inch-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
