Built from high speed steel with a coated finish, this bit features a 130-degree faceted drill point and a web-thinned, tapered web configuration that reduces thrust and improves centering. The right-hand spiral flute design promotes efficient chip evacuation. At 0.147 inches (wire size 26) in diameter, the short screw machine length provides added rigidity compared to jobber-length bits, making it well suited for precision drilling in tight spaces or on screw machine setups.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in metalworking applications where close-tolerance, high-cycle drilling is required. Its 5xD flute-to-diameter ratio and stub-length profile make it a practical choice for production environments including CNC machining centers, turret lathes, and manual drill press work on ferrous and non-ferrous stock. Machinists and tool-and-die professionals working with steel and aluminum will find the web-thinned point especially useful for starting holes cleanly without a center punch on softer materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 26 diameter: 0.147 inches with a tolerance of +0 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e130-degree faceted drill point for aggressive cutting on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces entry thrust and improves hole quality\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length adds rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for consistent chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-shank drill chucks.

Ensure the workpiece is securely clamped before drilling. This bit does not support coolant-through operation, so apply cutting fluid externally when drilling steel or stainless steel to manage heat. Follow applicable machine shop safety procedures and equipment manufacturer guidelines for spindle speeds and feed rates appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.147 inches (Wire Size 26 \/ 3.73 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\u003eDrill Point Angle\u003c\/strong\u003e: 130 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eSeries\u003c\/strong\u003e: 1100\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\u003eWeight\u003c\/strong\u003e: 0.015 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: 8595373\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752699003186,"sku":"8595373","price":47.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d250c1a1d57dcbd0fe6010f0bcf43bb0.jpg?v=1788929810","url":"https:\/\/voomisupply.com\/products\/osg-8595373-screw-machine-drill-bit-0-147-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
