Built from solid carbide and coated with TiAlN (titanium aluminum nitride), this bit handles elevated cutting temperatures without sacrificing edge integrity. The 140-degree split point angle combined with R-thinned web geometry reduces thrust force and improves centering on entry. At 107.00 mm overall length and a 14.00 mm diameter (0.5512 decimal inch), this is a compact, rigid tooling choice suited for CNC machining centers, drill presses, and production environments where hole accuracy and tool life are critical. Installed by machinists and toolroom technicians in metalworking and fabrication shops.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed primarily for stainless steel applications, where carbide substrate hardness and TiAlN coating lubricity provide a meaningful advantage over high-speed steel alternatives. The 3xD flute-to-diameter ratio and 60.00 mm flute length support chip evacuation in blind and through-hole configurations. Coolant-through capability makes it compatible with high-pressure coolant systems, extending tool life in continuous production runs. The straight-cylindrical shank seats securely in standard drill chucks and collet holders without special adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in stainless steel and difficult alloys\u003c\/li\u003e\n\u003cli\u003eTiAlN coating reduces friction and extends tool life at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree special point angle with R-thinned web for reduced entry thrust and accurate hole placement\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with high-pressure internal coolant systems\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry with 3xD ratio promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard collet chucks and drill holders\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 straight-shank collet or drill chuck toolholders accepting a 14.00 mm shank diameter. Primary workpiece material is stainless steel; the carbide substrate and TiAlN coating also support use in other ferrous and difficult-to-machine alloys. Conforms to DIN specification standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine in a full stop and lockout-tagout procedures in place. Ensure the collet or chuck bore matches the 14.00 mm shank diameter before tightening. When using the coolant-through feature, verify that coolant pressure and flow rate are within the machine spindle specifications before initiating the cut. Inspect the cutting edge for chipping or wear before each production run, as carbide tools can fail suddenly rather than gradually when pushed beyond their design envelope.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 14.00 mm (0.5512 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 107.00 mm (4.2126 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 60.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14.00 mm (0.5512 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4500425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738559775026,"sku":"4500425","price":303.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/795c41156a07cdab669a91657f6b76e8_b3845e06-037d-486f-8b0b-7d411227cd9b.jpg?v=1788801016","url":"https:\/\/voomisupply.com\/products\/accupro-4500425-14mm-carbide-drill-bit-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
