Built from solid carbide with a coated finish, this bit delivers the rigidity and heat resistance needed when working through tough workpiece materials. It features a 29\/64 inch (0.4531 inch) diameter, a 140-degree drill point angle, and a right-hand spiral flute configuration. Coolant-through capability supports chip evacuation and thermal management during extended cuts. The R-thinned web reduces cutting force at entry while the tapered web configuration maintains bit strength throughout the flute length. Licensed tradespeople and precision machining technicians rely on this geometry for accurate, consistent hole production.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production environments requiring stub-length rigidity and tight diameter tolerances. The Series 6500 design targets high-performance applications in steel, alloy steel, cast iron, titanium, and titanium alloy. The 3xD flute-to-diameter ratio and screw machine length body make it well-matched to CNC machining centers, drill presses, and turret lathes where short-reach setups minimize deflection. The straight-cylindrical shank seats cleanly in standard drill chucks and collet systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and thermal stability in ferrous and titanium materials\u003c\/li\u003e\n\u003cli\u003e140-degree split-point geometry reduces walking and lowers required thrust force at entry\u003c\/li\u003e\n\u003cli\u003eR-thinned web configuration decreases chisel edge length and improves chip flow\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole and high-speed operations\u003c\/li\u003e\n\u003cli\u003eCoated finish extends tool life when machining abrasive or work-hardening alloys\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.027 mm supports close-tolerance hole production\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drilling applications involving steel, alloy steel, cast iron, titanium, and titanium alloy workpieces.

Ensure the spindle and workpiece are fully secured before engaging the cut. When using coolant-through capability, confirm the machine spindle and toolholder are rated for internal coolant delivery before activating coolant flow. Inspect the bit for chipping or wear before each use, as carbide is brittle and should not be used if the cutting edge is damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 29\/64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.4531 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 11.51 mm\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 58.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 120.00 mm (4.72 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.355 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.95 inches L x 0.65 inches W x 0.6 inches H\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: 650045211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747592143154,"sku":"650045211","price":317.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_2b66b9a6-9bd1-45a9-8a6c-f9fd4bfc41b6.jpg?v=1788883071","url":"https:\/\/voomisupply.com\/products\/osg-650045211-screw-machine-drill-bit-29-64-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
