At 1\/2 inch in diameter with a 5-inch overall length and a 140-degree proprietary point angle, this bit is built for aggressive penetration with minimal walking at entry. The TiAlN (titanium aluminum nitride) coating extends tool life in high-heat cutting environments. A UR-thinned web reduces thrust requirements at the point. Right-hand cutting with a slow spiral flute geometry makes it well-suited for chip evacuation in tough, dense workpieces. Installed by machinists and tool-and-die tradespeople using CNC or manual drilling equipment.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in hardened materials including tool steel, hardened alloy steels, and similarly abrasion-resistant workpieces where a specialized carbide substrate and wear-resistant coating are required. The slow spiral flute design controls chip flow in materials that produce short, brittle chips. The straight cylindrical shank at 1\/2 inch diameter seats directly into standard drill chucks or collet-style toolholders without adapters. It is a single-unit item suited for both production and maintenance machining applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in hardened-material drilling\u003c\/li\u003e\n\u003cli\u003eTiAlN coating resists oxidation and extends cutting edge life at elevated temperatures\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle reduces thrust and centers accurately on entry\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry optimized for short-chip, hard-material applications\u003c\/li\u003e\n\u003cli\u003eUR-thinned web lowers axial cutting force at the drill point\u003c\/li\u003e\n\u003cli\u003eStraight 1\/2-inch shank fits standard chucks and collet toolholders directly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use carbide jobber drill for machining operations involving hardened materials.

Ensure the spindle and toolholder are clean and free of debris before seating the shank. Carbide tooling is brittle — avoid side loads, interrupted cuts without appropriate feed parameters, or dropping the bit on hard surfaces. Confirm spindle speed and feed rate are appropriate for the workpiece hardness before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.500 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.0625 inches (3-1\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches (1\/2 inch)\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 4500101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731798524210,"sku":"4500101","price":248.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88c458a44a09209f0783eb6430db45fe.jpg?v=1788735053","url":"https:\/\/voomisupply.com\/products\/accupro-4500101-jobber-drill-1-2-in-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
