At 3.30 mm in diameter with a 130-degree S-thinned point, it self-centers reliably and reduces thrust when entering harder workpiece materials. The two-flute spiral design with a tapered web configuration evacuates chips efficiently during blind-hole and through-hole operations. With an overall length of 68.00 mm and a 4.00 mm straight-cylindrical shank, this bit seats securely in standard drill chucks and collet holders. Machinists and tool-and-die professionals working in production or maintenance environments will find this Series 1600 bit suited to a range of drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for use on steel and stainless steel as well as non-ferrous materials including aluminum, aluminum alloy, and aluminum silicate. Typical applications include blind-hole drilling, cross-hole drilling, and self-centering entry cuts in both manual and CNC drilling operations. The TiAlN coating improves heat resistance at the cutting edge, making it a practical choice for dry or minimal-lubrication machining environments where tool life under elevated temperatures is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.30 mm diameter with a diameter tolerance of +0 to -0.018 mm for consistent fit in close-tolerance work\u003c\/li\u003e\n  \u003cli\u003e130-degree S-thinned point reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating increases surface hardness and heat resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003eVanadium high speed steel substrate provides toughness across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral with tapered web for effective chip evacuation in blind and cross-hole drilling\u003c\/li\u003e\n  \u003cli\u003e4.00 mm straight-cylindrical shank fits standard drill chucks and collet systems without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on primary workpiece materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate.

Before mounting or changing the bit, ensure the machine spindle is fully stopped and locked out per applicable safety procedures. Seat the shank fully and evenly in the chuck or collet before tightening to prevent runout. Do not exceed the recommended speed and feed parameters for the workpiece material and machine type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.30 mm (0.1299 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: S-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 68.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: S-Thinned\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\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\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: 0.025 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: 6253311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739013611826,"sku":"6253311","price":38.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16ddf913045f8e2c30c1beb34bb4e1b8_81fe84c8-3375-4f97-8f02-2499d6366e18.jpg?v=1788807978","url":"https:\/\/voomisupply.com\/products\/osg-6253311-jobber-drill-bit-3-30-mm-tialn-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
