Built to DIN 6537K specification, it features a 6.10 mm cutting diameter, a 140-degree split point for accurate starting and reduced thrust, and a multilayer TiAlN coating at the tip to extend tool life at elevated cutting temperatures. The straight-cylindrical shank measures 8.00 mm in diameter and seats securely in standard chucks and collets. This bit is suited for production drilling environments where cycle time and tool longevity are priorities.\u003c\/p\u003e\u003cp\u003eThis drill bit is used in CNC machining centers, drill presses, and screw machines handling ferrous and non-ferrous metals, stainless steels, cast iron, and hardened alloys. Its stub-length body and 3xD flute-to-diameter ratio make it well suited for short-reach, rigid setups where runout must be minimized. Coolant-through capability supports high-speed production drilling with through-spindle coolant systems, improving chip evacuation and thermal management at the cutting zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating extends cutting life under high heat conditions\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports through-spindle coolant for deep-hole chip evacuation\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional consistency and interchangeability\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds core strength and reduces cutting forces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series B051A-CPG stub-length carbide drill bit for use in standard straight-shank chucks and collets accepting an 8.00 mm shank diameter, in CNC and manual drilling applications requiring a 6.10 mm bore diameter per DIN 6537K.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the collet or chuck and verify runout with a dial indicator before production use. When using coolant-through capability, confirm that spindle coolant pressure and flow rate are within the machine tool manufacturer's recommended range before drilling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.10 mm (0.2402 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\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\u003eOverall Length\u003c\/strong\u003e: 79.00 mm (3.1102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm (1.3386 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 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: 24.00 mm (0.9449 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.02 mm (0.0402 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.015 to 0.000 mm (-0.0006 to 0.0000 inches)\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: 0.08 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: 4151149\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749117362482,"sku":"4151149","price":159.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/366d4104940bc2e26e3ea3661c2c6ea4.jpg?v=1788902277","url":"https:\/\/voomisupply.com\/products\/kennametal-4151149-solid-carbide-stub-drill-bit-6-10mm","provider":"Voomi Supply","version":"1.0","type":"link"}
