Designed for demanding material removal in hardened workpieces, it features a TiAlN coating that extends tool life at elevated cutting temperatures. The slow spiral flute geometry promotes chip control in tough materials where standard flute designs struggle. A UR-thinned web reduces thrust requirements and improves center cutting performance. This drill is intended for use by machinists and tooling professionals in production or job-shop environments where carbide tooling is standard practice.\u003c\/p\u003e\u003cp\u003eThe 4500105 is suited for drilling hardened materials in precision machining applications. The straight cylindrical shank with a 0.5000-inch diameter seats in standard drill chucks or collet-style tool holders. With a flute-to-diameter ratio of 4xD, it handles moderate depth drilling without excessive deflection. The DIN specification designation ensures dimensional consistency for tooling setups that require standardized drill geometry. This bit is sold individually and is appropriate for both CNC and manual machine setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened material applications\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal and oxidation resistance at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle reduces thrust and improves entry in hard workpieces\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute design promotes controlled chip evacuation in tough materials\u003c\/li\u003e\n\u003cli\u003eUR-thinned web for reduced drilling resistance and improved center cutting\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length carbide drill for use in hardened materials; fits any drill chuck or collet holder accepting a 0.5000-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this drill bit should be performed by a qualified machinist following standard tooling practices. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the chuck or collet and verify runout before beginning a cut. Coolant-through capability is not present on this tool, so external coolant or cutting fluid application should be used where the workpiece material and machine setup allow.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.4040 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\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Slow 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\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: UR-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Specialized\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: 4500105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738292322610,"sku":"4500105","price":231.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f9be60fdcbec22799e652af3a6b5bdb.jpg?v=1788797823","url":"https:\/\/voomisupply.com\/products\/accupro-4500105-jobber-drill-letter-y-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
