Built to DIN specification, it features a 140-degree split point with R-thinned web geometry that reduces thrust and improves chip evacuation on entry. The TiAlN coating extends tool life in high-heat applications. At 3.20 mm (0.1260 inches) in diameter with a 2.5984-inch overall length, this drill fits standard straight-shank toolholding systems on CNC machining centers and manual drill presses. It is specified for machinists, toolmakers, and production shops running precision drilling operations in stainless steel and similarly tough alloys.\u003c\/p\u003e\u003cp\u003eThe 4500160 is rated for stainless steel as its primary workpiece material, making it a go-to choice for shops drilling 300-series or 400-series stainless, hardened alloys, and high-nickel materials where heat buildup and work hardening are concerns. The coolant-through design channels cutting fluid directly to the cutting edge, reducing thermal stress and extending run life in deep-hole applications. A 5xD flute-to-diameter ratio provides adequate chip clearance in moderate-depth holes typical of production fixture and component work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard, abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and reduces built-up edge in stainless and high-alloy steels\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eR-thinned web reduces chisel-edge contact and lowers feed force requirements\u003c\/li\u003e\n\u003cli\u003eCoolant-through capability delivers fluid directly to the cutting zone for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute in regular configuration for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in straight-shank toolholders and drill chucks accepting a 6 mm shank diameter. Suitable for CNC machining centers, drill presses, and milling machines equipped for coolant-through tooling. Primary application is stainless steel; also applicable to other high-hardness ferrous alloys within the 3.00 mm to 4.00 mm drill size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine fully powered down and the spindle locked. Verify shank runout after seating in the holder, as carbide drills are sensitive to concentricity issues that can cause premature breakage. Coolant-through connections should be confirmed and flow tested before production runs. Handling carbide tooling requires care to avoid impact or dropping, which can cause chipping of the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.20 mm (0.1260 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 (1.1024 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\u003ePoint 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\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 4500160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740939157810,"sku":"4500160","price":120.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30e23f14797f3e863903dbdb78cfc864.jpg?v=1788828488","url":"https:\/\/voomisupply.com\/products\/accupro-4500160-jobber-drill-3-20mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
