It measures 17\/64 inches (0.2656 inches) in diameter with an overall length of 4.2969 inches and a flute length of 2.2031 inches. The 140-degree point angle provides aggressive cutting geometry suited for hard and abrasive materials. A TiAlN coating adds thermal resistance and surface hardness, extending tool life in high-speed or dry-cutting operations. This bit is sized at a 5xD flute-to-diameter ratio and features R-thinned web geometry to reduce thrust and improve chip evacuation. Machinists and tool-and-die professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe 4500181 is built for drilling stainless steel and similarly hard ferrous and non-ferrous alloys. Its right-hand spiral flute and straight cylindrical shank make it compatible with standard drill chucks and CNC toolholders. Coolant-through capability supports high-pressure coolant delivery for deep-hole applications where heat buildup and chip packing are concerns. Typical use cases include precision hole-making in fabrication shops, production machining environments, and maintenance operations where stainless steel or high-alloy workpieces are common.\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 improves thermal performance and extends tool life in high-speed applications\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces walking and suits flat or curved entry surfaces on hard stock\u003c\/li\u003e\n  \u003cli\u003eR-thinned web reduces cutting thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-pressure internal coolant delivery\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard CNC and manual drill press setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank drill chucks and CNC toolholders accepting a 0.2656-inch (17\/64 inch) shank diameter.

Ensure the machine spindle and chuck are fully powered down and locked out before inserting or removing the bit. Verify chuck runout is within acceptable limits before cutting  -  solid carbide is brittle and sensitive to lateral loading from misaligned toolholding. When using coolant-through capability, confirm the machine spindle and coolant system are rated for through-spindle delivery before pressurizing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 17\/64 inches (0.2656 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.2969 inches (109.14 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.2031 inches (55.96 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2656 inches (17\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\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\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\u003eCoating\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: 4500181\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742345232690,"sku":"4500181","price":173.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7997eee5755abe00c1a67c6f471b0cdc.jpg?v=1788836891","url":"https:\/\/voomisupply.com\/products\/accupro-4500181-jobber-drill-17-64-in-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
