Built from solid carbide with a coated finish, this bit delivers superior wear resistance and extended tool life compared to standard high-speed steel tooling. The 140-degree split point reduces thrust and improves centering accuracy on entry. At 0.1299 inches (3.30 mm) in diameter, it features a right-hand spiral flute design with a web-thinned, tapered web configuration for efficient chip evacuation. Coolant-through capability supports high-speed production environments where heat management is critical. Licensed machinists and tool-and-die professionals are the primary installers of this bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for cutting steel, alloy steel, cast iron, titanium, and titanium alloys — materials common in aerospace, automotive, and precision machining operations. The screw machine length profile (shorter overall length than jobber bits) provides increased rigidity and reduced deflection in CNC machining centers, drill presses, and turret lathes. The straight-cylindrical shank with a 4.00 mm (0.1575 inch) diameter is compatible with standard collet and chuck systems. The 3xD flute-to-diameter ratio suits through-hole and shallow-blind-hole work at production volumes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with coated finish for extended tool life in ferrous and titanium workpieces\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle for reduced entry thrust and improved self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed, high-feed production drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web (R-Thinned) reduces cutting force and chip packing\u003c\/li\u003e\n  \u003cli\u003eScrew machine length provides added rigidity and minimized deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eOSG Series 6500 high-performance designation for demanding material applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces.

Ensure the spindle and workholding are powered down and locked out before inserting or removing the bit from the chuck or collet. Solid carbide bits are brittle compared to high-speed steel — avoid side loading, interrupted cuts beyond the tool's rated capacity, or dropping the bit on hard surfaces. Verify coolant-through supply pressure and flow are correctly configured before initiating production runs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1299 inches (3.30 mm)\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 Length\u003c\/strong\u003e: 20.00 mm (0.787 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm (2.913 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\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, Alloy 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\u003eSeries\u003c\/strong\u003e: 6500\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: 0.03 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: 8690330\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737060868402,"sku":"8690330","price":145.51,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30a14012bcdc8d214b7ab7cb02a1c6c4.jpg?v=1788783760","url":"https:\/\/voomisupply.com\/products\/osg-8690330-screw-machine-drill-bit-0-1299in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
