Built from solid carbide and coated with TiAlN, it holds up under the heat and abrasion generated when cutting stainless steel and other hard alloys. The 140-degree split point reduces walking at entry and lowers the thrust needed to start the cut. With a flute length of approximately 2.24 inches and an overall length of approximately 3.74 inches, this bit fits standard drill chucks and CNC setups running straight-shank tooling. Coolant-through capability makes it well suited for automated machining environments where chip evacuation and heat management are critical.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for metalworking applications where tool life and hole quality in tough materials are priorities. Its R-thinned web reduces cutting resistance, making it a practical choice for production drilling in stainless steel, hardened alloys, and similar ferrous materials. The spiral flute geometry promotes consistent chip removal in both manual and CNC-controlled operations. Machinists and toolroom technicians working in manufacturing, fabrication, and precision machining shops are the primary installers and users of this bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life under high-heat cutting conditions\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces entry walking and thrust requirements\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation in automated setups\u003c\/li\u003e\n\u003cli\u003eR-thinned web lowers cutting resistance at the drill center\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use taper length drill bit for applications requiring a 13\/64 inch straight-shank carbide bit with a 140-degree point and coolant-through capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Secure the straight shank firmly in a compatible chuck or collet before operation and verify that runout is within acceptable limits for the application. When using the coolant-through feature, confirm that the machine spindle and toolholder are set up to deliver coolant at adequate pressure. Do not use carbide drills in hand-held drilling operations, as carbide is brittle and susceptible to breakage from lateral loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 13\/64 inches (0.2031 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\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\u003eFlute Length\u003c\/strong\u003e: 57 mm (approximately 2.24 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 95 mm (approximately 3.74 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 Length to Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4500463\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732348436786,"sku":"4500463","price":190.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c7976ee3e7b45e15a54f2490aa352f4.jpg?v=1788741905","url":"https:\/\/voomisupply.com\/products\/accupro-4500463-taper-length-drill-bit-13-64-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
