Built from solid carbide and coated with a multilayer TiAlN finish at the tip, this bit delivers hardness and heat resistance suited for high-speed or production drilling. It features a 140-degree standard point angle for reduced thrust and cleaner entry, a 5.40 mm cutting diameter, and a right-hand spiral flute configuration. With an overall length of 66.00 mm and a straight cylindrical shank, it fits standard drill chucks and tool holders. Machinists and tool-and-die professionals are the primary users of this type of bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for stub-length drilling operations where rigidity and minimal deflection are priorities. The 3xD flute-to-diameter ratio and tapered web configuration make it well suited for through-hole and blind-hole work in ferrous metals, alloys, and similar hard materials on CNC machining centers, drill presses, and screw machines. The Series B041A-CPG designation places it within a defined family of solid carbide stub drills conforming to DIN 6537K specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and long tool life in hard-material drilling\u003c\/li\u003e\n  \u003cli\u003eTiAlN multilayer coating at tip reduces heat buildup and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle lowers entry thrust and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003eStub length design minimizes deflection in short-reach drilling setups\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks without modification\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-production drill bit for use in CNC machining centers, screw machines, and drill presses accepting a 6.00 mm straight shank.

Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the straight shank fully into the collet or chuck and verify runout is within acceptable limits before commencing drilling. Do not exceed the maximum recommended drilling depth of 20.00 mm for this stub-length configuration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.40 mm (0.2126 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN Multilayer (TiN Tip)\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: 28.00 mm (1.1024 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\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 (0.0354 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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.012 to 0.000 mm (-0.0005 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: B041A-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: 0.05 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: 4150216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750959546674,"sku":"4150216","price":96.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/027550a92e9fb7c9c67a753ee7e2e1a8_7de54806-e5ef-4f3c-8f71-9687edc16d1f.jpg?v=1788920832","url":"https:\/\/voomisupply.com\/products\/kennametal-4150216-screw-machine-drill-bit-5-40mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
