It measures 10.30 mm (0.4055 inches) in diameter with a 140-degree proprietary point angle engineered to reduce walking and improve entry accuracy on tough workpieces. The TiAlN (Titanium Aluminum Nitride) coating provides thermal resistance and extended tool life under high-speed cutting conditions. Overall length is 111.00 mm (4.3701 inches), with a 63.00 mm (2.4803 inches) flute length. Installed by machinists and tool-and-die professionals, this drill is suited for CNC and manual drilling operations where hardened steel or similar materials are encountered.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is optimized for hardened materials, where standard HSS tooling would fail prematurely. The slow spiral flute geometry reduces heat buildup and chip packing in difficult-to-machine workpieces. The straight cylindrical shank at 12 mm diameter fits standard drill chucks and collet systems. It is a right-hand cutting tool with a 4xD flute-to-diameter ratio and UR-thinned web, making it appropriate for precision production environments and job-shop applications requiring consistent hole quality in hardened stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened material drilling\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and extends cutting life at elevated speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree proprietary point angle reduces drill walk and improves hole entry accuracy\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute geometry minimizes heat buildup and controls chip evacuation\u003c\/li\u003e\n  \u003cli\u003eUR-thinned web reduces thrust force and improves cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eStraight 12 mm shank is compatible with standard chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in hardened materials; fits standard drill chucks and collet systems accepting a 12 mm straight cylindrical shank.

Ensure the machine spindle and chuck are fully stopped and locked out before mounting or removing the drill bit. Carbide tooling is brittle — avoid side loading, interrupted cuts without proper feed adjustments, or dropping the bit on hard surfaces. Verify spindle runout is within acceptable tolerance before use to prevent premature breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.30 mm (0.4055 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 111.00 mm (4.3701 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 63.00 mm (2.4803 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\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\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\u003eShank Diameter\u003c\/strong\u003e: 12 mm\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 4500109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731142082866,"sku":"4500109","price":169.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e09bb66ac268badadc2ab5252e0d519a.jpg?v=1788727466","url":"https:\/\/voomisupply.com\/products\/accupro-4500109-solid-carbide-jobber-drill-10-30-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
