Built from solid carbide and coated with TiAlN (titanium aluminum nitride), this bit delivers superior heat and wear resistance compared to standard HSS tooling. It features a 17.00 mm diameter, a 140-degree split point angle, and a right-hand spiral flute with R-thinned web geometry. The TiAlN coating allows sustained cutting speeds in abrasive and high-temperature environments. Machinists and tool-and-die professionals select this bit for precision work requiring tight tolerances and consistent hole quality.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in CNC machining centers, drill presses, and manual milling operations where controlled, accurate drilling is required. Its primary workpiece material rating is stainless steel, making it well suited for fabrication shops, aerospace component work, and industrial manufacturing environments where stainless alloys are common. The straight-cylindrical shank provides secure chuck engagement across standard toolholding setups. The screw machine length (stub) configuration offers increased rigidity over jobber-length bits, reducing deflection in deep-entry situations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for maximum rigidity and tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating increases surface hardness and heat resistance for extended cutting performance\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eR-thinned web reduces cutting resistance and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for heat management in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral geometry optimized for stainless steel and other difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003eDIN specification designation ensures dimensional conformance to international standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for primary use in stainless steels.

Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation to prevent runout. Always verify spindle speed and feed rate recommendations for carbide tooling in the specific workpiece material before cutting. Coolant-through capability should be used when available to maximize tool life and manage heat in stainless steel applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 17.00 mm (0.6693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 123.00 mm (4.8425 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 73.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 18.00 mm (0.7087 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\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\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\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-to-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\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 4500444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746868003122,"sku":"4500444","price":507.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/795c41156a07cdab669a91657f6b76e8_2dc93dbe-d808-470c-80c9-e20edb4a7771.jpg?v=1788874170","url":"https:\/\/voomisupply.com\/products\/accupro-4500444-drill-bit-17mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
