Built to DIN specification, it features a 140-degree split point geometry with UR-thinned web for reduced entry force and a TiAlN coating that extends tool life under high heat and abrasion. The straight-cylindrical shank measures 6 mm in diameter and seats securely in standard drill chucks or collet holders. With an overall length of 2.835 inches (72 mm) and a 5.00 mm cutting diameter, it is sized for precision work in CNC machining centers, drill presses, and handheld power tools used in tool-and-die, aerospace, and general metalworking applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for machining hardened steels and difficult ferrous alloys where elevated cutting temperatures are a concern. The slow spiral flute design promotes chip control in tough materials, reducing built-up edge and heat concentration at the cutting zone. The 4xD flute-to-diameter ratio and 1.260-inch (32 mm) flute length are appropriate for moderate-depth holes in workpieces requiring tight positional tolerance. This is a single-piece precision cutting tool intended for use by machinists and toolroom technicians working to close tolerances.\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\u003e140-degree split point with UR-thinned web for fast entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal and oxidation resistance at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry promotes chip evacuation and reduces heat buildup in tough alloys\u003c\/li\u003e\n\u003cli\u003eDIN specification compliance ensures dimensional consistency for tool presetting and CNC use\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, straight-cylindrical shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and rotary toolholders accepting a 6 mm straight-cylindrical shank.

Seat the shank fully into the chuck or collet and verify runout before cutting. Coolant-through is not supported on this tool; apply external coolant or cutting fluid appropriate to the workpiece material when required. Inspect the cutting edges for chipping or wear before each use, as carbide tooling is brittle and can fracture if operated under excessive lateral load or interrupted cuts without proper feed and speed parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.00 mm (0.1969 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 72.00 mm (2.835 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 32.00 mm (1.260 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm straight-cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Slow Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeb Thinning\u003c\/strong\u003e: UR-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials\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\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: 4500074\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730646761778,"sku":"4500074","price":57.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b7302f789315a2bd8bbe44d2ec81f40.jpg?v=1788720793","url":"https:\/\/voomisupply.com\/products\/accupro-4500074-carbide-jobber-drill-5mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
