Built from solid carbide and coated with TiAlN (titanium aluminum nitride), it delivers heat resistance and extended tool life in applications where standard HSS bits fall short. The 140-degree split point reduces walking and improves chip evacuation at entry. With a 3.00 mm cutting diameter, 0.1181 decimal inch equivalent, and an overall length of 62.00 mm (2.44 inches), this is a compact, rigid bit suited for CNC machining centers, drill presses, and screw machine operations. Machinists, toolroom techs, and production floor operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is optimized for stainless steels and other work-hardening alloys where cutting edge integrity is critical. The screw machine length design keeps the bit short and stiff, minimizing deflection in tight setups or multi-spindle machines. Coolant-through capability supports high-speed operations where internal flushing extends tool life and improves hole quality. The straight-cylindrical shank at 6.00 mm (0.2362 inches) fits standard collets and drill chucks across most CNC and manual setups. The flute-to-diameter ratio is 3xD, and the web is R-thinned for reduced thrust force at entry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in stainless steel and hard alloys\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e140-degree special point geometry reduces entry walking and improves chip flow\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed, high-feed drilling operations\u003c\/li\u003e\n\u003cli\u003eR-thinned web reduces axial thrust and lowers entry force\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length minimizes deflection in close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers, screw machines, and drill presses equipped with standard collet or drill chuck toolholding that accepts a 6.00 mm straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet bore size matches the 6.00 mm shank before tightening. Use manufacturer-recommended cutting speeds and feeds for solid carbide tooling in stainless steel; exceeding rated parameters will damage the coating and cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 62.00 mm (2.44 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 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: Special\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\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: 0.13 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: 4500361\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731908952370,"sku":"4500361","price":98.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/795c41156a07cdab669a91657f6b76e8_74208f7e-abc2-4fa7-a902-f5b31a8823dd.jpg?v=1788736424","url":"https:\/\/voomisupply.com\/products\/accupro-4500361-screw-machine-drill-bit-3-00-mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
