It is manufactured from solid carbide and coated with TiAlN (titanium aluminum nitride) for extended tool life and heat resistance at elevated cutting speeds. The bit measures 35\/64 inches (0.5469 inches) in diameter with a 140-degree web-thinned point that reduces entry force and improves centering on hard materials. Overall length is 5.276 inches with a 2.756-inch flute length. The straight cylindrical shank and right-hand spiral flute design make it compatible with standard drill chucks and CNC toolholders. This bit is suited for machine shops, fabrication facilities, and production environments.\u003c\/p\u003e\n\u003cp\u003eThe 4500371 is rated for use on stainless steels as its primary workpiece material, making it a go-to choice when drilling 300- and 400-series stainless in production or maintenance settings. The screw machine length (stub) body provides added rigidity compared to jobber-length bits, which reduces deflection and chatter during deep or interrupted cuts. The 3xD flute-to-diameter ratio supports efficient chip evacuation in short-to-medium-depth holes. Coolant-through capability allows internal coolant delivery directly to the cutting zone, extending tool life and improving chip flushing in CNC machining center applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and extends tool life at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree R-thinned web point reduces thrust force and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the cutting edge\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body minimizes deflection for improved hole accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand 2-flute regular spiral geometry for efficient chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drilling machines equipped with standard straight-shank toolholders; primary rated workpiece material is stainless steel per series ASSC140-TA-CL specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is intended for use by machinists and CNC operators in a machine tool environment. Secure the straight shank firmly in a drill chuck or collet toolholder before operation and verify runout before beginning a cut. Always engage coolant-through flow before contact with the workpiece when using the internal coolant feature. Do not use this bit in hand-held drills; it is designed for rigid machine setups only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 35\/64 inches (0.5469 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.276 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.756 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Web-Thinned (R-Thinned)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ASSC140-TA-CL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727097364786,"sku":"4500371","price":321.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/350c9d611cbf6028256a7afcacff2526.jpg?v=1788673261","url":"https:\/\/voomisupply.com\/products\/accupro-4500371-drill-bit-35-64-in-140-deg-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
