Built from solid carbide and coated with a multilayer TiAlN finish at the tip, this bit delivers extended tool life in hardened steels, cast iron, and other abrasive workpiece materials. It features a 140-degree point angle for reduced thrust and improved centering, a 2-flute regular spiral configuration, and a straight cylindrical shank measuring 6.00 mm in diameter. Overall length is 62.00 mm (2.4409 inches). The tapered web construction adds rigidity while maintaining chip evacuation. Coolant-through capability is supported, making it well-suited for automated or CNC machine tool setups where through-spindle coolant is available.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in screw machine operations, CNC machining centers, and production drilling applications where tight tolerances and repeatability are required. With a drill diameter of 3.40 mm (0.1339 inches) and a maximum drilling depth of 14.00 mm (0.5512 inches), it fits applications calling for stub-length rigidity over extended reach. The B051A-CPG series designation confirms this is a production-grade carbide stub drill built to DIN 6537K standards. Machinists, toolroom technicians, and CNC operators in metalworking shops are the primary installers and users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high wear resistance in ferrous and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN multilayer coating at the tip extends tool life under elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces axial thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with through-spindle coolant delivery systems\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds core strength while supporting chip flow\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a production-grade stub-length drill bit for use in CNC machining centers, screw machines, and any machine tool spindle accepting a 6.00 mm straight cylindrical shank.

Ensure the machine spindle is fully powered down and locked out before inserting or removing the bit from the tool holder. Verify shank seating and runout with appropriate gauging before initiating a cut. Do not exceed the rated maximum drilling depth of 14.00 mm per pass without confirmed chip clearance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.40 mm (0.1339 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 62.00 mm (2.4409 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 mm (0.7874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\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\u003eDrill Point Length\u003c\/strong\u003e: 0.55 mm (0.0218 inches)\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\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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 Multilayer (Tip)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches (-0.012 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: B051A-CPG\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: 0.04 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4151107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731080905010,"sku":"4151107","price":124.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_f6fd1924-240c-4bd6-a5b2-3f0dd8dec9f6.jpg?v=1788726739","url":"https:\/\/voomisupply.com\/products\/kennametal-4151107-screw-machine-drill-bit-3-40mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
