It features a 4.60 mm diameter, a 140-degree standard point angle, and a multilayer TiAlN coating applied at the tip to extend tool life and reduce heat buildup at the cutting zone. The overall length is 66.00 mm (2.5984 inches) with a straight cylindrical shank diameter of 6.00 mm. This bit belongs to the Series B041A-CPG and is manufactured to DIN 6537K specification. It is installed and used by machinists, tool-and-die technicians, and CNC operators working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for short-reach drilling applications where rigidity and accuracy are priorities over depth. The stub-length body reduces deflection and improves hole location accuracy in CNC machining centers, drill presses, and screw machines. A maximum drilling depth of 17.00 mm and a flute-to-diameter ratio of 3xD make it appropriate for through-holes and shallow blind holes in ferrous metals, cast iron, stainless steel, and similar materials. The right-hand cutting direction and regular spiral flute support standard chip evacuation in conventional drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust force and improves centering on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eTiAlN tip coating extends tool life by reducing heat transfer into the cutting edge\u003c\/li\u003e\n  \u003cli\u003eStub-length body minimizes deflection for tighter hole tolerances in high-cycle production drilling\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration strengthens the core and improves drill stability\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 6537K specification for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production-use drill bit in the KENNAMETAL Series B041A-CPG. Fits standard straight-shank tool holders and drill chucks accepting a 6.00 mm shank diameter. Suitable for use in CNC machining centers, manual drill presses, and screw machine setups where stub-length carbide drills are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight cylindrical shank fully and evenly in the tool holder or drill chuck and verify runout before beginning a cut. Do not use this bit without coolant or cutting fluid in applications where workpiece material hardness or feed rates generate elevated cutting temperatures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.60 mm (0.1811 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 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\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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.76 mm (0.0299 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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (Tip)\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: -0.012 to 0.000 mm (-0.0005 to 0.0000 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\u003ePackage Dimensions\u003c\/strong\u003e: 7.0 x 0.8 x 0.8 inches\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: 4150203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739159494962,"sku":"4150203","price":100.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bee3f9638d7491ce019436ff8411b83.jpg?v=1788810515","url":"https:\/\/voomisupply.com\/products\/kennametal-4150203-screw-machine-drill-bit-4-60mm","provider":"Voomi Supply","version":"1.0","type":"link"}
