Built to DIN 6537K specifications, it features a 2.30 mm (0.0906 inch) diameter with a 140-degree split point for accurate entry and reduced thrust. The multilayer TiAlN coating at the tip extends tool life in ferrous and non-ferrous materials. With an overall length of 58.00 mm (2.2835 inches) and a straight cylindrical shank of 4.00 mm (0.1575 inch) diameter, this bit is suited for CNC machining centers, drill presses, and screw machine operations where rigidity and repeatability are critical.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in precision machining applications including production drilling, screw machine work, and short-hole drilling operations. The stub length geometry increases rigidity over jobber-length equivalents, making it well suited for tight setups and high-feed-rate drilling in machine shops and manufacturing environments. It is typically installed and used by machinists and CNC operators working with metal components requiring tight hole tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle for precise entry and reduced walking\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating at tip for extended tool life and heat resistance\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length at 58.00 mm OAL for improved rigidity in short setups\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production drill bit in the KENNAMETAL B041A-CPG series, suited for standard drill chucks and collets accepting a 4.00 mm straight shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a compatible drill chuck or collet system; ensure the shank is fully seated and secured before operation. Power down or de-energize the machine and engage all safety locks before changing tooling. Handle carbide tooling carefully to avoid chipping the cutting edge during setup. Follow applicable machine tool manufacturer guidelines and shop safety procedures when operating at rated speeds and feeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.30 mm (0.0906 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 58.00 mm (2.2835 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13.00 mm (0.5118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 28.00 mm (1.1024 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.36 mm (0.0143 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 (Tip)\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: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.014 to 0.000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B041A-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4151645\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727127052594,"sku":"4151645","price":94.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b02913eab3783d3aa8c6c1d389efaf7f.jpg?v=1788673788","url":"https:\/\/voomisupply.com\/products\/kennametal-4151645-screw-machine-drill-bit-2-30mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
