It features a 5.00 mm diameter solid carbide construction with a TiAlN coating, delivering heat and wear resistance needed for tough materials. The 140-degree web-thinned point geometry reduces thrust force and improves centering accuracy at entry. With an overall length of 66.00 mm and a 6.00 mm straight cylindrical shank, this bit fits standard drill chucks and collet holders. It is designed for machinists and tooling professionals working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling stainless steels and other difficult-to-machine materials where tool life and hole quality are critical. The screw machine length format provides added rigidity compared to jobber length bits, making it a practical choice for CNC machining centers, drill presses, and manual machines where shorter stick-out is preferred. The coolant-through design supports internal coolant delivery for improved chip evacuation and thermal management during high-cycle operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and rigidity in stainless steel applications\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal and oxidation resistance at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e140-degree web-thinned point reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant or through-spindle coolant delivery\u003c\/li\u003e\n\u003cli\u003eScrew machine length format increases rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting with regular spiral flute for efficient chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance replacement or direct-fit drill bit for use in standard straight-shank drill chucks and collet systems accepting a 6.00 mm shank diameter, per DIN specification, in the 5.00 mm to 6.50 mm drill bit size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed and operated by qualified machinists or tooling technicians familiar with cutting tool safety practices. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet runout is within acceptable tolerance before use, as excessive runout accelerates wear on carbide tooling. When using the coolant-through feature, confirm the spindle coolant system is compatible and set to the appropriate flow rate for the material being drilled.\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: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 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\u003ePoint Type\u003c\/strong\u003e: Web-Thinned (R-Thinned)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ASSC140-TA-CL\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: 4500337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750736494898,"sku":"4500337","price":99.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6cae5d7f459129b028ff9a1bb562f00.jpg?v=1788919148","url":"https:\/\/voomisupply.com\/products\/accupro-4500337-screw-machine-drill-bit-5mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
