At 11\/64 inches (0.1719 inches) in diameter, it features a 140-degree split point for aggressive penetration and reduced walking on entry. The TiAlN coating provides thermal resistance and extended tool life at elevated cutting speeds. Coolant-through capability makes it well-suited for deep-hole applications where chip evacuation and heat management are critical. This bit runs right-hand cutting with a regular spiral flute and is manufactured to ISO specification. Machinists and toolroom technicians working in production or maintenance environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in stainless steel and other hard or abrasive workpiece materials where standard high-speed steel tooling falls short. The TiAlN coating handles the heat generated when cutting austenitic stainless grades. The 5xD flute-to-diameter ratio provides adequate flute length for chip clearance in moderate-depth holes. At 3-15\/16 inches overall length with a 1-3\/4-inch flute length, it fits standard drill chucks and CNC toolholders with a 15\/64-inch straight cylindrical shank. The R-thinned web reduces thrust requirements and helps maintain accuracy in harder materials.\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 for thermal protection and extended cutting life\u003c\/li\u003e\n  \u003cli\u003e140-degree proprietary point angle with R-thinned web reduces thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and heat control in deep holes\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with 5xD ratio balances chip flow and flute strength\u003c\/li\u003e\n  \u003cli\u003eISO specification designation for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in stainless steel workpieces as the primary application material.

Ensure the spindle and workpiece are secured before operation and that the correct spindle speed and feed rate for solid carbide tooling in the target material are confirmed before cutting. Use appropriate cutting fluid or coolant supply when running the coolant-through feature to maximize tool life and chip evacuation. Do not run solid carbide drills in hand-drill applications or unsupported setups, as carbide is brittle and susceptible to breakage under lateral loading.\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: 11\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1719 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: Proprietary\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (Decimal Inch)\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (Inch)\u003c\/strong\u003e: 3-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (Decimal Inch)\u003c\/strong\u003e: 3.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Inch)\u003c\/strong\u003e: 15\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2344 inches\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 4500187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741007380786,"sku":"4500187","price":150.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cc85dc9c867804c00034ddcd66fda34.jpg?v=1788828843","url":"https:\/\/voomisupply.com\/products\/accupro-4500187-jobber-drill-bit-11-64-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
