It measures 0.124 inches (3.15 mm) in diameter with a 140-degree split point and an overall length of approximately 2.91 inches (74 mm). The 2-flute spiral design with R-thinned web reduces thrust and improves chip evacuation. Coolant-through capability supports extended tool life in production environments. This bit is intended for use by machinists and tool room technicians working with precision metal components requiring tight tolerances and consistent hole quality.\u003c\/p\u003e\n\u003cp\u003eThe OSG 8665315 is suited for screw machine operations, CNC drilling, and short-hole drilling applications in production or job shop settings. Its compact screw machine length provides added rigidity compared to jobber-length bits, making it appropriate for close-tolerance work. Primary workpiece materials include steel, stainless steel, cast iron, titanium, and titanium alloys. The 3xD flute-to-diameter ratio supports chip clearing in interrupted or continuous cuts across these material groups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces entry force and improves self-centering on hard metals\u003c\/li\u003e\n  \u003cli\u003eR-thinned, tapered web lowers axial thrust during drilling\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for heat management in production runs\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute with straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0 to -0.018 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, cast iron, titanium, and titanium alloy workpieces.

Secure the straight-cylindrical shank fully in a precision drill chuck or collet before operation and verify runout is within acceptable limits for the application. Carbide bits are brittle — avoid side loads, sudden feed changes, or interrupted cuts without appropriate feed and speed parameters for the workpiece material. Engage coolant-through supply before initiating the cut when using internal coolant capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.124 inches (3.15 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74 mm (approximately 2.91 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 19 mm (approximately 0.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Titanium, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1000 to 0.1500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 8665315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728986308914,"sku":"8665315","price":122.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2eb0072ff612055705bfaa4bcea4c71d.jpg?v=1788698442","url":"https:\/\/voomisupply.com\/products\/osg-8665315-solid-carbide-screw-machine-drill-bit-0-124-in","provider":"Voomi Supply","version":"1.0","type":"link"}
