Built from solid carbide and finished with a multilayer TiAlN coating, this bit delivers the hardness and thermal resistance needed for tight-tolerance hole making in ferrous metals, cast iron, hardened steels, and similar materials. The 140-degree split-point geometry reduces thrust force and improves centering without a pilot hole. Overall length is 66.00 mm (2.5984 inches), with a right-hand spiral flute configuration and a straight cylindrical shank. Licensed machinists, tool-and-die techs, and CNC operators are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for screw machine operations, CNC machining centers, drill presses, and multi-spindle production setups where shorter flute length and maximum rigidity are priorities. The 4.20 mm cutting diameter and 6.00 mm shank diameter fit standard collets and drill chucks common to production floor equipment. Maximum drilling depth is 17.00 mm (0.6693 inches), consistent with its 3xD flute-to-diameter ratio. The Series B041A-CPG designation identifies this bit within the KENNAMETAL stub drill family, which is designed for precision work in tight axial clearance situations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating reduces friction and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle for reduced entry thrust and self-centering performance\u003c\/li\u003e\n  \u003cli\u003eStub (screw machine) length body minimizes deflection and improves hole straightness\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds core strength along the flute length\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard collet chucks and drill press quills\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement drill bit for production machining applications requiring a 4.20 mm diameter solid carbide stub drill with a straight shank, conforming to DIN 6537K. Fits standard 6.00 mm collet and drill chuck toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or CNC operators following standard toolholding procedures. Secure the shank fully within the collet or chuck to the recommended engagement depth before initiating the cut. Power down and de-energize the machine spindle before changing or inspecting tooling. Do not use this bit as a reamer or apply lateral force during drilling, as solid carbide is brittle under bending loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.20 mm (0.1654 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\u003eFlute Length\u003c\/strong\u003e: 24.00 mm (0.9449 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 17.00 mm (0.6693 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\u003eDrill Point Length\u003c\/strong\u003e: 0.69 mm (0.0272 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\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\u003eFlute By 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Multilayer TiAlN (TiN Tip)\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\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 Bit Size Range\u003c\/strong\u003e: 3.50 to 5.00 mm (0.1500 to 0.2000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: B041A-CPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 0.05 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: 4150197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740527624498,"sku":"4150197","price":96.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0ee9762c9a7034e14dc9828c7f7b47f.jpg?v=1788825693","url":"https:\/\/voomisupply.com\/products\/kennametal-4150197-screw-machine-drill-bit-4-20mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
