It features a 5.50 mm diameter, a 140-degree split point angle, and a TiAlN (titanium aluminum nitride) coating that improves heat resistance and extends tool life at elevated cutting speeds. The overall length is 3.228 inches (82.00 mm), with a flute length of 1.732 inches (44.00 mm) and a 6 mm straight cylindrical shank. The 2-flute regular spiral design with R-thinned web promotes efficient chip evacuation. This bit is installed and used by machinists, toolroom technicians, and precision metalworking tradespeople.\u003c\/p\u003e\n\u003cp\u003eThe 4500137 is rated for primary use in stainless steel, a material class that demands sharp geometry, rigid substrates, and effective coating to resist work hardening and heat buildup at the cutting edge. The 140-degree point angle reduces thrust force on entry and improves centering without a separate spotting operation in many setups. Coolant-through capability supports high-pressure through-spindle coolant delivery, making this bit well suited for CNC machining centers and production drilling environments where thermal management is critical. The 5xD flute-to-diameter ratio provides adequate chip clearance for moderate-depth holes in the stainless steel range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves oxidation resistance and extends tool life at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree proprietary point angle reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-pressure through-spindle coolant delivery\u003c\/li\u003e\n  \u003cli\u003eR-thinned web reduces chisel-edge contact and lowers axial cutting force\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for standard CNC and manual drill press setups\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance replacement jobber drill for CNC machining centers, drill presses, and manual machines equipped with a collet or chuck accepting a 6 mm straight shank. Primary workpiece material rating is stainless steel; the solid carbide substrate and TiAlN coating also support use in other ferrous and hard alloy materials at appropriate cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with carbide tooling requirements. Secure the straight shank in a precision collet or drill chuck rated for the intended spindle speed before use. Carbide is brittle compared to high-speed steel  -  avoid side loading, interrupted cuts without verified setup rigidity, or dropping the tool on hard surfaces. When using through-spindle coolant, confirm coolant pressure and flow rate are within the machine and toolholder specification before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.50 mm (0.2165 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\u003ePoint Type\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 44.00 mm (1.732 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 82.00 mm (3.228 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 0.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 4500137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740799828274,"sku":"4500137","price":122.05,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b84f143b0563e1a5c4294bb61d0c33bb.jpg?v=1788827492","url":"https:\/\/voomisupply.com\/products\/accupro-4500137-solid-carbide-jobber-drill-5-50-mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
