Built from solid carbide and coated with a multilayer TiAlN finish at the tip, it delivers extended tool life under demanding cutting conditions. The bit features a 140-degree point angle for reduced thrust and self-centering entry, a 2-flute regular spiral configuration, and an overall length of 4.2126 inches (107.00 mm). The straight cylindrical shank measures 0.5512 inches (14.00 mm) in diameter. This bit is installed by machinists, tool-and-die specialists, and maintenance technicians working with CNC machining centers, drill presses, and screw machines.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for stub-length drilling operations where rigidity and minimal deflection are priorities. The 3xD flute-to-diameter ratio supports chip evacuation in short-hole applications. It carries a maximum drilling depth of 1.6929 inches (43.00 mm), making it appropriate for through-holes and blind holes in production environments. The Series B041A-CPG designation places it within a family of solid carbide stub drills conforming to DIN 6537K specification. Right-hand cutting direction is standard. Applications include general metalworking, precision component manufacturing, and high-volume production drilling where tool consistency and dimensional accuracy are required.\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 at the tip extends tool life under heat and abrasion\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n  \u003cli\u003eStub (screw machine) length design maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration supports chip flow and cutting stability\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 a DIN 6537K-compliant stub drill for use in standard straight-shank toolholders and collet chucks accepting a 14.00 mm shank diameter. Compatible with CNC machining centers, drill presses, and screw machines configured for right-hand cutting tools in the 0.5000 to 0.6000 inch drill bit size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the machine powered down and locked out per applicable OSHA lockout\/tagout procedures. Verify the toolholder collet or chuck is rated for the 14.00 mm straight shank before seating the bit. Do not exceed the rated maximum drilling depth of 43.00 mm to avoid tool breakage or workpiece damage. Inspect the cutting edge and coating condition before each use; carbide tooling is brittle and should not be dropped or struck against hard surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13.50 mm (0.5315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 107.00 mm (4.2126 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 60.00 mm (2.3622 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.00 mm (1.6929 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14.00 mm (0.5512 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45.00 mm (1.7717 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 2.33 mm (0.0916 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\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\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 Length Type\u003c\/strong\u003e: Stub (Screw Machine)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches (-0.018 to 0.000 mm)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 4150328\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733183299890,"sku":"4150328","price":238.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/832118eb378b2cd19816ae74ed7126ac.jpg?v=1788752472","url":"https:\/\/voomisupply.com\/products\/kennametal-4150328-screw-machine-drill-bit-13-50mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
