It measures 0.1232 inches (3.13 mm) in diameter with an overall length of 1.969 inches (50.00 mm) and a straight-cylindrical shank diameter of 0.157 inches (4.00 mm). The bit is manufactured from high speed steel with a coated finish, features a 130-degree faceted drill point, and incorporates a web-thinned, tapered web configuration for reduced thrust and improved chip evacuation. Two spiral flutes with a 5xD flute-to-diameter ratio handle material removal efficiently.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and repair drilling in shop and field environments. Its screw machine length profile makes it ideal for use in CNC machining centers, drill presses, and hand-operated equipment where a short, rigid bit reduces deflection. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The Series 1100 designation places it within OSG's high-performance tooling lineup, making it a go-to choice for machinists, tool and die technicians, and maintenance professionals working with ferrous and non-ferrous metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1232 inch (3.13 mm) diameter with tolerance of +0 to -0.018 mm for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e130-degree faceted drill point reduces walking and improves entry 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\u003eScrew machine length for maximum rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with two spiral flutes for efficient chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Ensure the workpiece is securely clamped and the spindle speed is set to a value appropriate for the workpiece material and bit diameter. Use cutting fluid or coolant appropriate to the workpiece material to maximize tool life; note this bit does not support coolant-through delivery. Inspect the drill point for wear or chipping before each use and replace if cutting edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1232 inches (3.13 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.969 inches (50.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.709 inches (18.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.157 inches (4.00 mm)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eWeight\u003c\/strong\u003e: 0.015 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: 8595313\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737458639154,"sku":"8595313","price":40.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93971c7e855b2124ffb33eb9cdeab9f3.jpg?v=1788788818","url":"https:\/\/voomisupply.com\/products\/osg-8595313-screw-machine-drill-bit-0-1232-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
