It features a 140-degree split point with UR-thinned web geometry that reduces entry force and helps center the drill without a pilot hole. The TiAlN coating provides thermal resistance and extended tool life in high-heat cutting environments. At 5.50 mm (0.2165 inches) in diameter and 75.00 mm (2.9528 inches) overall length, it runs in a straight-cylindrical shank measuring 6 mm and is suited for CNC machining centers and manual drill presses alike. Installation is handled by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis bit is optimized for hardened materials including hardened steels, tool steels, and similar ferrous workpieces where conventional HSS tooling loses edge life quickly. The slow spiral flute geometry and 4xD flute-to-diameter ratio help evacuate chips efficiently in deep-hole applications while maintaining rigidity. It follows DIN specification standards and is packaged as a single unit. Typical applications include precision hole work in mold and die, aerospace component machining, and general metalworking shops requiring consistent performance on tough substrates.\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 applications\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides high-temperature oxidation resistance and extended cutting life\u003c\/li\u003e\n  \u003cli\u003e140-degree proprietary point with UR-thinned web reduces thrust force and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute design promotes chip control and stability in hard, abrasive workpieces\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eMeets DIN specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide jobber drill for use in standard drill chucks and collet systems accepting a 6 mm straight shank, suitable for CNC and manual machining setups targeting hardened material applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit should be installed by a qualified machinist following standard tooling setup procedures for carbide cutting tools. Ensure the spindle is fully stopped and the machine is powered off before changing tooling. Carbide is brittle — avoid side loading, interrupted cuts without proper support, or impacts that can chip the cutting edge. Confirm correct spindle speed and feed rate for the target material hardness before engaging the cut; no coolant-through capability is present on this tool, so adequate external coolant or dry-cutting conditions appropriate to TiAlN-coated carbide should be observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.50 mm (0.2165 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75.00 mm (2.9528 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 35.00 mm (1.3780 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials\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: 0.17 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: 4500070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734280634674,"sku":"4500070","price":60.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6bcd6d54470baf43b7bb993366f9ab.jpg?v=1788762246","url":"https:\/\/voomisupply.com\/products\/accupro-4500070-jobber-drill-5-50mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
