It features a solid carbide construction with a TiAlN (titanium aluminum nitride) coating that extends tool life in abrasive and high-heat applications. The 140-degree web-thinned point reduces thrust, improves chip evacuation, and aids self-centering on entry. At 5.512 inches overall length with a 2.953-inch flute length, this is a stub-length format that maximizes rigidity and minimizes deflection. The straight cylindrical shank measures 0.5781 inches in diameter, matching the bit diameter for direct chuck mounting. Two regular spiral flutes handle chip removal efficiently, and coolant-through capability supports high-speed production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for cutting stainless steels and other difficult-to-machine metals where tool rigidity and heat resistance are critical. The screw machine length format is well suited for CNC machining centers, drill presses, and manual machine tools in shop environments where short overall length reduces runout and chatter. It fits applications in manufacturing, fabrication, and maintenance where precision hole quality in tough alloys is required. The 3xD flute-to-diameter ratio supports accurate hole geometry without the deflection risk of longer jobber-length tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for maximum rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and extends tool life in stainless steel and high-alloy workpieces\u003c\/li\u003e\n  \u003cli\u003e140-degree R-thinned web point reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed and high-feed production drilling\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length format minimizes deflection compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flutes for predictable chip flow and evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and machine tool spindles accepting a 0.5781-inch straight cylindrical shank.

Ensure the chuck or collet is rated for the shank diameter before seating the bit. Coolant-through setups require proper coolant pressure and flow to the spindle before commencing a cut. Do not use this bit in hand-held drills; it is intended for rigid machine tool 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: 37\/64 inch (0.5781 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\u003ePoint Type\u003c\/strong\u003e: Web-Thinned (R-Thinned)\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: 5.512 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.953 inches (2-61\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5781 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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steels\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: 4500365\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747623174450,"sku":"4500365","price":353.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d8319725d5b0482f96152af99bf8741.jpg?v=1788883632","url":"https:\/\/voomisupply.com\/products\/accupro-4500365-screw-machine-drill-bit-37-64-inch-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
