Built from solid carbide with a TiAlN (titanium aluminum nitride) coating, this bit is designed to handle abrasive and hard materials where standard high-speed steel tooling falls short. The 140-degree split point reduces walking and lowers thrust requirements at entry. With a 95 mm flute length and 142 mm overall length, this bit reaches deeper than a jobber-length drill while maintaining rigidity. The straight cylindrical shank measures 10 mm in diameter, seating securely in standard drill chucks and tool holders. Coolant-through capability supports high-speed production drilling.\u003c\/p\u003e\u003cp\u003eThis drill bit is primarily used in machining applications targeting stainless steel and other difficult-to-machine materials. The R-thinned web and 8xD flute-to-diameter ratio support efficient chip evacuation in deep-hole operations. Typical installations include CNC machining centers and manual drill presses in job shops, fabrication facilities, and production environments where tool life and hole quality are critical. Machinists and tooling specialists select this bit for interrupted cuts, gummy alloys, and applications where tool geometry directly affects surface finish and dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high hardness and heat resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life and supports dry or minimal-lubrication cutting\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces entry thrust and minimizes workpiece deformation\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels coolant directly to the cutting edge for deep-hole operations\u003c\/li\u003e\n\u003cli\u003eR-thinned web improves chip flow and reduces cutting force\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with straight cylindrical shank fits standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and drill presses equipped with standard straight-shank toolholders accepting a 10 mm shank diameter.

Ensure the machine spindle is fully stopped and locked out before installing or removing the bit. Solid carbide tooling is brittle and should not be dropped or used in setups with excessive runout, as chipping or breakage can result. Verify that coolant-through passages are clear and that the machine tool holder provides sufficient clamping force for the shank diameter before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9 mm (0.3543 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 142 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 95 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral, 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\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-to-Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel\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: 4500505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732509524274,"sku":"4500505","price":227.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bab7da54e4ceb169089df8816063a83c.jpg?v=1788743780","url":"https:\/\/voomisupply.com\/products\/accupro-4500505-taper-length-drill-bit-9mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
