Built to DIN specification, it features a 140-degree split point with UR-thinning to reduce thrust and improve entry on tough workpieces. The TiAlN coating adds thermal resistance and hardness, extending tool life in abrasive and heat-generating cuts. At 19\/64 inch (0.2969 inch) diameter with a 3-3\/8 inch overall length, this bit is sized for general jobber-length drilling applications. Machinists and tool-and-die professionals are the primary users. It is sold individually.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use on hardened materials including hardened steels and similar abrasive workpieces. The slow spiral flute geometry is selected specifically for these applications, managing chip evacuation in materials that generate fine, packed chips. The straight 3\/8 inch shank fits standard drill chucks and collet systems on CNC machining centers, drill presses, and manual mills. It is not designed for coolant-through applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with UR-thinning reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry optimized for chip control in hardened and abrasive workpieces\u003c\/li\u003e\n\u003cli\u003eStraight 3\/8 inch shank for broad compatibility with standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eDIN specification construction for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and manual milling machines equipped with standard drill chucks or collet systems accepting a 3\/8 inch straight shank.

Ensure the shank is fully seated and the chuck or collet is torqued to the machine manufacturer's specification before operation. This bit is not rated for coolant-through use; apply cutting fluid externally as appropriate for the workpiece material. Inspect the cutting edge and TiAlN coating for wear or chipping before each use, as carbide tooling is brittle and should not be used if chipped.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/64 inch (0.2969 inch)\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\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary (UR-Thinned)\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: 1.7813 inches (1-25\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches (3-3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\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: 0.13 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: 4500040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737186468146,"sku":"4500040","price":132.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/894b3bfd0f8330c2552b68dca1f25dd9.jpg?v=1788785362","url":"https:\/\/voomisupply.com\/products\/accupro-4500040-jobber-drill-19-64-inch-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
