It features a 7.60 mm (0.2992 inch) diameter, a 140-degree proprietary point angle, and a TiAlN (titanium aluminum nitride) coating that extends tool life under heat and abrasion. The bit runs right-hand cutting with a regular spiral flute and an R-thinned web for improved chip evacuation and reduced thrust at entry. Overall length is 3.58 inches (91 mm) with a 2.09-inch (53 mm) flute length. A straight cylindrical shank at 8 mm diameter seats securely in standard drill chucks or collet holders. This drill is suited for machinists, tool-and-die shops, and precision fabricators working with tight tolerances.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for primary use in stainless steel and is classified as a high-performance grade tool. The 5xD flute-to-diameter ratio supports deeper drilling applications where chip packing is a concern. Coolant-through capability allows cutting fluid to be delivered directly to the cutting edge, which is critical when drilling stainless steel or other work-hardening alloys at production feed rates. The DIN specification designation confirms dimensional conformance to international tooling standards, making it compatible with standard toolholding systems found on CNC machining centers and drill presses.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends tool life at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle reduces walking and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eR-thinned web lowers thrust force and improves chip flow at the drill tip\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers fluid directly to the cutting zone for thermal management\u003c\/li\u003e\n\u003cli\u003eDIN-spec straight cylindrical shank fits standard chucks and collet toolholding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance jobber drill for use in CNC machining centers, drill presses, and manual mills equipped with standard collet or drill chuck toolholding accepting an 8 mm straight shank. Primary target workpiece material is stainless steel; the TiAlN coating and solid carbide substrate also support use in other hard or abrasive ferrous materials within the 7.00 mm to 8.00 mm drill size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill should be performed by a qualified machinist familiar with speeds, feeds, and toolholding practices for solid carbide tooling. Ensure the machine spindle and toolholder are clean and free of runout before seating the shank, as carbide is brittle and sensitive to lateral load. When enabling coolant-through operation, verify that the machine spindle and toolholder support internal coolant delivery at the required pressure. Follow the machine builder and tooling manufacturer guidelines for appropriate cutting parameters to avoid tool fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.60 mm (0.2992 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91 mm (3.58 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm (2.09 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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 Designation\u003c\/strong\u003e: DIN\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: 4500228\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737706168626,"sku":"4500228","price":136.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2192822720e70b6a31df7e37844b79b8.jpg?v=1788792556","url":"https:\/\/voomisupply.com\/products\/accupro-4500228-jobber-drill-7-60mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
