Built from solid carbide with a multilayer TiAlN coating and a TiN tip, it delivers extended tool life in hard and abrasive materials. The 140-degree split-point geometry reduces thrust and improves centering without a pilot hole. At 2.2835 inches overall length with a 0.5118-inch flute length, this stub-length format maximizes rigidity in short-reach drilling applications. Coolant-through capability supports chip evacuation and thermal control in high-cycle or deep-hole scenarios. Licensed HVAC techs, machinists, and tool-room professionals handling tight-tolerance work will recognize the DIN 6537K specification as a reliable benchmark.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for stub-length drilling operations where rigidity and runout control are priorities. The straight cylindrical shank at 4.00 mm (0.1575 inches) diameter seats cleanly in standard drill chucks and collet holders. The 3xD flute-to-diameter ratio and regular spiral flute design handle chip flow efficiently in through-hole and blind-hole applications. Maximum drilling depth is 10.00 mm (0.3937 inches), making it appropriate for shallow, precision bores in metalworking, tooling, and component manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating with TiN tip for extended tool life and heat resistance\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and temperature management\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration maintains core strength across the flute length\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-compatible stub-length drill bit conforming to DIN 6537K, Series B051A-CPG, for use in standard drill chucks and collet systems accepting a 4.00 mm straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or toolroom technicians familiar with carbide tooling handling procedures. Ensure the machine spindle is fully stopped and power is locked out before seating or removing the bit. Carbide is brittle — avoid side loading, interrupted cuts beyond rated parameters, or dropping the bit on hard surfaces. Verify coolant flow is active before engaging the cut when using the through-coolant feature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.10 mm (0.0827 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 Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.33 mm (0.0130 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Multilayer TiAlN with TiN Tip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches (-0.014 to 0.000 mm)\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\u003eSeries\u003c\/strong\u003e: B051A-CPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 4148810\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727263695154,"sku":"4148810","price":124.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c62274822371b51de2599c21d06dd17.jpg?v=1788675638","url":"https:\/\/voomisupply.com\/products\/kennametal-4148810-2-10mm-carbide-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
