It measures 4.20 mm in diameter with a 140-degree split point and a TiAlN (titanium aluminum nitride) coating that improves heat resistance and extends tool life at higher cutting speeds. The overall length is 2.91 inches with a flute length of 1.42 inches. The straight cylindrical shank measures 6 mm and seats directly into standard drill chucks or collets. This drill is built for professional machinists, tool-and-die shops, and CNC operators who need consistent, repeatable hole quality in production environments.\u003c\/p\u003e\u003cp\u003eThis drill is rated for primary use in stainless steel, where tool deflection, heat buildup, and edge wear are common failure points for lesser tooling. The 5xD flute-to-diameter ratio and regular spiral flute geometry support consistent chip evacuation in both manual and CNC drilling operations. Coolant-through capability allows internal coolant delivery for extended run times and improved hole finish in deep or interrupted cuts. The R-thinned web reduces entry thrust, which is especially useful when drilling work-hardened or austenitic stainless grades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating increases surface hardness and thermal protection at the cutting edge\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point geometry reduces entry thrust and walking\u003c\/li\u003e\n\u003cli\u003eR-thinned web improves penetration in stainless steel and other tough alloys\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 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 jobber drill for CNC machining centers, drill presses, and manual machines equipped with standard straight-shank toolholders or collet chucks accepting a 6 mm shank. Primary workpiece material rating is stainless steel; the TiAlN coating also supports use in other ferrous and heat-resistant alloys.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with cutting tool setup and speeds-and-feeds selection. Secure the shank fully in the collet or chuck before operation and verify runout does not exceed acceptable tolerances for the application. Always follow machine guarding protocols and wear appropriate eye protection. Consult the machine and toolholder manufacturer specifications for recommended RPM and feed rates for carbide tooling in stainless steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.20 mm (0.1654 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm (2.91 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm (1.42 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\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: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: 4500150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741647995186,"sku":"4500150","price":123.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e9fb7fc51607edc26c68bab393ec376.jpg?v=1788832713","url":"https:\/\/voomisupply.com\/products\/accupro-4500150-solid-carbide-jobber-drill-4-20-mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
