Measuring 7\/64 inch (0.1094 inch) in diameter with a 140-degree split-point geometry, it delivers fast penetration and self-centering entry without a pilot hole. The multilayer TiAlN coating applied at the tip extends tool life in demanding materials. At 2.28 inches overall length with a 0.158-inch straight cylindrical shank, this bit is sized for use in CNC machining centers, screw machines, and short-reach drilling setups. Coolant-through capability supports chip evacuation and heat control in deep-hole cycles. Right-hand cut, two-flute spiral design with a tapered web rounds out the construction. Installation is performed by qualified machinists and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThis stub-length drill bit is designed for precision drilling in metalworking environments where rigidity and accuracy are critical. The reduced overall length compared to standard jobber bits minimizes deflection, making it well suited for tight-tolerance holes in ferrous and non-ferrous metals. Typical applications include automated screw machine work, CNC turning centers, and VMC fixture drilling. The DIN 6537K specification ensures dimensional consistency for production environments where tool interchangeability matters. Maximum drilling depth is 0.47 inches (12.00 mm), appropriate for the 3xD flute-to-diameter ratio of this series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in metalworking applications\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle for fast, self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eTiAlN multilayer coating at tip extends tool life in abrasive and high-temperature cuts\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and thermal management\u003c\/li\u003e\n  \u003cli\u003eStub length (2.28 inches OAL) minimizes deflection for tighter hole tolerances\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for production-grade dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the KENNAMETAL B051A-CPG series, designed for use in screw machines, CNC machining centers, and short-reach drilling fixtures requiring a 7\/64 inch diameter, straight-shank stub-length solid carbide drill bit conforming to DIN 6537K.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the spindle and workpiece are fully stopped and machine is powered down or in a safe state before changing tooling. Confirm shank diameter compatibility with the collet or chuck prior to seating the bit. When using coolant-through capability, verify coolant pressure and flow rate are set according to the machine tool specification before initiating a cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.28 inches (58.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.67 inches (17.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.47 inches (12.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.158 inches (4.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.10 inches (28.00 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\u003eDrill Point Length\u003c\/strong\u003e: 0.018 inches (0.45 mm)\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\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\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\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\u003eWeight\u003c\/strong\u003e: 0.02 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: 4148853\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750754976050,"sku":"4148853","price":124.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5607e17dfee06ced60a8fa8e2cf89999.jpg?v=1788919395","url":"https:\/\/voomisupply.com\/products\/kennametal-4148853-screw-machine-drill-bit-7-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
