It measures 4.40 mm (0.1732 inches) in diameter with an overall length of 74.00 mm (2.9134 inches) and a flute length of 36.00 mm (1.4173 inches). The 140-degree split point geometry reduces walking and thrust requirements, making it well suited for harder alloys. A TiAlN (Titanium Aluminum Nitride) coating provides heat resistance and extends tool life in high-speed applications. This drill is installed and operated by machinists, tool-and-die makers, and maintenance technicians working in metal fabrication and production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered primarily for stainless steel and other hard ferrous and non-ferrous alloys where heat buildup and tool wear are the primary concerns. The 5xD flute-to-diameter ratio, right-hand spiral flute configuration, and R-thinned web reduce cutting resistance and improve chip evacuation. The straight cylindrical shank with a 6 mm diameter fits standard drill chucks and collet systems. Coolant-through capability makes it compatible with CNC machining centers and drill presses equipped with through-spindle coolant delivery, supporting deeper hole applications with reduced recutting of chips.\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 improves thermal resistance and extends cutting tool life\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle reduces drill walk and axial thrust\u003c\/li\u003e\n\u003cli\u003eR-thinned web lowers cutting force and improves point strength\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports deep-hole drilling with through-spindle coolant systems\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to DIN specification standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance replacement jobber drill for applications in stainless steel and similar hard workpiece materials; fits standard drill chucks and collet holders accepting a 6 mm straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Ensure the spindle is fully stopped and the machine is de-energized or locked out before mounting or removing the drill bit. Confirm the chuck or collet is properly sized for the 6 mm shank and that runout is within acceptable limits before operation. When using coolant-through capability, verify the machine spindle and toolholder are rated and configured for through-coolant delivery before applying cutting fluid pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.40 mm (0.1732 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm (2.9134 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\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\u003eCoating\/Finish\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\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\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 Designation\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: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4500148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743922454834,"sku":"4500148","price":119.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7f2bae741c8fa943fa9de5bb615ef31.jpg?v=1788851338","url":"https:\/\/voomisupply.com\/products\/accupro-4500148-solid-carbide-jobber-drill-4-40-mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
