It measures 12.00 mm in diameter with an overall length of 119.00 mm and a flute length of 71.00 mm. The 140-degree proprietary point geometry reduces thrust and improves centering at entry. A TiAlN (titanium aluminum nitride) coating provides thermal resistance and extended tool life at elevated cutting speeds. The slow-spiral, two-flute design promotes chip evacuation in deep-hole applications. This drill is suited for use by machinists and tool-and-die professionals working with CNC machining centers and conventional drill presses.\u003c\/p\u003e\u003cp\u003eThe 4500128 is built for production and job-shop environments where carbide tooling is required to maintain hole tolerances and surface finish in hard or abrasive workpiece materials such as cast iron, hardened steel, and high-temp alloys. The straight cylindrical shank with a 12 mm shank diameter fits standard drill chucks and collet systems without modification. The UR-thinned web reduces cutting resistance and supports consistent performance at the rated flute-to-diameter ratio of 4xD. This drill ships individually and is sold as a single unit.\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 increases surface hardness and thermal stability at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle for improved self-centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eSlow-spiral two-flute geometry promotes chip flow in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eUR-thinned web lowers cutting force at the chisel edge\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide jobber drill conforming to DIN specification, suitable for use in CNC machining centers, drill presses, and multi-spindle setups accepting a 12 mm straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with carbide tooling. Secure the shank fully in a matched collet or chuck before operation and verify runout before cutting. Carbide tooling is brittle — avoid side loading, interrupted cuts without proper setup, or hand-tightening in undersized holders. Follow machine manufacturer guidelines for spindle speed and feed rate for the workpiece material and drill diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12.00 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 119.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 4xD\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\u003ePoint Type\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: UR-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4500128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727182430514,"sku":"4500128","price":205.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4213e8f125b1c4bc518e46935904a178_d22e42b8-2dd9-4b1f-8d6e-bc611848f4a3.jpg?v=1788674425","url":"https:\/\/voomisupply.com\/products\/accupro-4500128-solid-carbide-jobber-drill-12mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
