Built from high speed steel with a coated finish, it measures 0.1457 inches (3.70 mm) in diameter with a 130-degree faceted point angle optimized for drilling into steel, stainless steel, aluminum, and aluminum alloys. The two-flute spiral design with a web-thinned, tapered web configuration reduces thrust and improves chip evacuation. This bit is installed by machinists, tool-and-die professionals, and maintenance technicians working on precision drilling applications where stub-length rigidity is required.\u003c\/p\u003e\n\u003cp\u003eThe OSG 61537 is suited for screw machine operations, CNC drilling setups, and bench drill applications requiring a short, rigid drill bit. Its straight-cylindrical shank is compatible with standard drill chucks and collet systems. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The 5xD flute-to-diameter ratio provides stability at depth while keeping the tool compact for close-tolerance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1457 inch (3.70 mm) diameter with a tight tolerance of +0 to -0.018 mm for precision fitment\u003c\/li\u003e\n  \u003cli\u003e130-degree faceted point angle reduces walking and improves centering on hard materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting thrust and extends tool life\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for wear resistance\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral design promotes efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drill chucks and collet holders accepting a 4.00 mm (approximately 0.157 inch) straight-cylindrical shank.

Secure the straight-cylindrical shank firmly in the chuck or collet before operation to prevent runout. Use appropriate cutting fluid or lubricant when drilling steel or stainless steel to manage heat buildup. Inspect the cutting edges and point before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1457 inches (3.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 52.00 mm (approximately 2.047 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 mm (approximately 0.787 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 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: Faceted\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: 61537\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51751217955122,"sku":"61537","price":42.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed03d96f7ad153ec9b1ea4429f9619f3.jpg?v=1788922311","url":"https:\/\/voomisupply.com\/products\/osg-61537-screw-machine-drill-bit-0-1457-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
