It features a 3\/16 inch (0.1875 inch decimal) diameter, a 140-degree web-thinned point, and a solid carbide construction with a TiAlN coating for extended tool life and heat resistance. The overall length is 3.543 inches with a 1.575-inch flute length and a straight cylindrical shank measuring 0.2344 inches in diameter. Designed for a 3xD flute-to-diameter ratio, this bit delivers controlled chip evacuation and consistent hole quality. It is suited for use in CNC machining centers, drill presses, and production environments where precision and durability are required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in stainless steels, making it a practical choice for fabrication shops, mechanical contractors, and machinists working with corrosion-resistant alloys. The screw machine length profile keeps the tool short and rigid, reducing deflection during entry. Coolant-through capability allows shops running high-pressure coolant systems to extend tool life and maintain tight tolerances on deep or interrupted cuts. Right-hand cutting direction is standard for conventional spindle rotation setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiAlN coating for heat and wear resistance in stainless steel applications\u003c\/li\u003e\n  \u003cli\u003e140-degree web-thinned point reduces thrust and improves self-centering on tough materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with high-pressure through-spindle coolant systems\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides rigidity and minimizes deflection in short-reach applications\u003c\/li\u003e\n  \u003cli\u003e3xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance replacement-style drill bit for use in standard straight-shank drill chucks and collet systems across CNC machining centers, drill presses, and similar equipment.

Ensure the machine spindle is fully stopped and locked out before changing or seating the bit. Confirm shank diameter compatibility with the chuck or collet before tightening to manufacturer-specified clamping torque for that workholding system. When using coolant-through capability, verify that the machine spindle supports through-spindle coolant delivery before engaging high-pressure flow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.543 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2344 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\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\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: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4500305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734721495346,"sku":"4500305","price":145.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d724311a3e3f332bb5e48fe5e6f8924d.jpg?v=1788765958","url":"https:\/\/voomisupply.com\/products\/accupro-4500305-screw-machine-drill-bit-3-16-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
