Built to DIN 6537K specification, it features a 140-degree standard point angle and a multilayer TiAlN coating at the tip for heat and wear resistance in demanding drilling applications. The straight cylindrical shank measures 6.00 mm (0.2362 inches) in diameter. Overall length is 66.00 mm (2.5984 inches). The two-flute, right-hand spiral design with a tapered web provides efficient chip evacuation and stable cutting action. Coolant-through capability is included, supporting extended tool life in deep or high-cycle drilling operations. Licensed machinists and CNC operators are the primary installers and users of this bit.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for precision metal-cutting applications where a short, rigid drill body is required. The stub length format reduces deflection in screw machine, turret lathe, and CNC machining center setups. The TiAlN tip coating makes it well suited for drilling alloy steels, stainless steels, cast iron, and similar ferrous materials at elevated surface speeds. The coolant-through design supports both flood and high-pressure through-spindle coolant delivery, making it appropriate for production drilling environments where cycle times and tool life are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in high-speed cutting\u003c\/li\u003e\n\u003cli\u003e140-degree point angle for self-centering entry and reduced thrust in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN multilayer tip coating extends tool life in abrasive and ferrous materials\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with through-spindle and flood coolant systems\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length minimizes deflection for accurate, repeatable hole placement\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification for dimensional consistency and machine compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification solid carbide stub drill for use in screw machines, CNC lathes, and machining centers with straight-shank toolholding systems accepting a 6.00 mm (0.2362 inch) shank diameter.

Ensure the spindle and machine are fully powered down and locked out before loading or changing tooling. Secure the straight shank firmly in a collet or drill chuck rated for the shank diameter before operation. Verify coolant-through passages are clear and that coolant pressure is set to the machine specification before running at full cycle speed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2130 inches\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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 Length\u003c\/strong\u003e: 28.00 mm (1.1024 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: 20.00 mm (0.7874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.90 mm (0.0355 inches)\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: -0.0005 to 0.0000 inches (-0.012 to 0.000 mm)\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: Yes\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: 0.05 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: 4151141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735008870706,"sku":"4151141","price":124.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_ed69d061-b653-4fd1-9853-a2ca35137269.jpg?v=1788769148","url":"https:\/\/voomisupply.com\/products\/kennametal-4151141-drill-bit-size-3-solid-carbide-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
