Built from vanadium high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in demanding production environments. The bit measures 7.7 mm in diameter (0.3031 inch decimal equivalent) with an overall length of 119 mm (approximately 4.69 inches) and a flute length of 75 mm (approximately 2.95 inches). The S-thinned point reduces thrust force and improves self-centering at entry. Licensed machinists, tool-and-die technicians, and maintenance professionals reach for this bit in both manual and CNC drilling setups.\u003c\/p\u003e\u003cp\u003eThe OSG 62577 is suited for drilling blind holes, cross holes, and through holes in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The 120-degree point angle and regular spiral geometry make it a practical general-purpose choice across a wide range of shop and field applications. The straight-cylindrical shank with an 8 mm shank diameter seats securely in standard drill chucks and collet holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium high speed steel construction for toughness and heat resistance\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eS-thinned point improves self-centering and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003e120-degree point angle suited for drilling steel, stainless steel, and aluminum\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular-spiral, two-flute design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with straight-cylindrical shank for secure chuck seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting an 8 mm straight-cylindrical shank.

Always set spindle speed appropriate to the workpiece material and bit diameter — consult a speeds-and-feeds reference for the specific material being drilled. Coolant through is not supported on this bit; apply cutting fluid externally when drilling steel or stainless steel to manage heat. Inspect the cutting edges for wear before each use and replace when chipping or excessive dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.7 mm (0.3031 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 119 mm (approximately 4.69 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 75 mm (approximately 2.95 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 120 degrees\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 -0.022 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: 0.085 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: 62577\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730203574578,"sku":"62577","price":86.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e423ce07c9d4a94e93058857fc46990_92c64c36-6079-4dfa-a30d-8c91ae4b083e.jpg?v=1788713287","url":"https:\/\/voomisupply.com\/products\/osg-62577-jobber-drill-bit-7-7mm-hss-tin-coated","provider":"Voomi Supply","version":"1.0","type":"link"}
