It measures 9\/64 inches (0.1406 inches decimal) in diameter with a 3-5\/8 inch overall length and a 140-degree split-point geometry. The TiAlN coating improves heat resistance and tool life when cutting hard materials. A straight cylindrical shank provides secure chuck retention, and the R-thinned web reduces thrust and improves chip evacuation. Licensed machinists, tool-and-die shops, and maintenance technicians working with stainless steel and other tough alloys are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in stainless steel and is suited for CNC machining centers, drill presses, and hand-held drilling operations where dimensional accuracy and finish quality are critical. The 5xD flute-to-diameter ratio and regular spiral flute design support consistent chip clearing in deep-hole applications. Coolant-through capability makes it compatible with through-spindle coolant setups common in production machining environments. The 15\/64 inch shank diameter fits standard drill chucks and collet systems used in both manual and automated machine tool setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating enhances heat resistance and extends tool life at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces walking and improves entry accuracy on hard workpieces\u003c\/li\u003e\n  \u003cli\u003eR-thinned web lowers drilling thrust and promotes cleaner chip formation\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with through-spindle coolant delivery systems\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute for standard CNC and manual drill applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance replacement jobber drill for applications in stainless steel and similarly hard alloys. Fits any standard drill chuck or collet accepting a 15\/64 inch (0.2344 inches decimal) straight shank.

Ensure the machine spindle is fully stopped and the chuck or collet is properly torqued before beginning a drilling operation. When using with through-spindle coolant, confirm that coolant pressure and flow rate are within the machine tool manufacturer's specifications. Carbide bits are brittle compared to high-speed steel  -  avoid lateral loading or prying, as this can cause chipping or fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Inch)\u003c\/strong\u003e: 9\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches (3.6250 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-47\/64 inches (1.7344 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/64 inches (0.2344 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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: 0.17 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: 4500189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744324452658,"sku":"4500189","price":152.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d7c61843d81a29a60aad6eb289512d0.jpg?v=1788855719","url":"https:\/\/voomisupply.com\/products\/accupro-4500189-solid-carbide-jobber-drill-9-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
