Built to DIN 6537K specification, it features a 4.00 mm diameter, a 140-degree standard point angle, and a multilayer TiAlN coating applied at the tip for extended tool life and heat resistance at elevated cutting speeds. The overall length is 66.00 mm, with a 6.00 mm straight cylindrical shank. Two regular spiral flutes evacuate chips efficiently. This bit is suited for use in CNC machining centers, drill presses, and screw machine setups where a rigid, short-body drill is required for accurate, high-feed-rate hole-making.\u003c\/p\u003e\u003cp\u003eThe 4150193 is intended for stub-length drilling in production machining environments, including automotive, aerospace, and general metalworking shops. Its compact flute length of 24.00 mm and maximum drilling depth of 17.00 mm make it appropriate for shallow, high-tolerance holes in ferrous and non-ferrous materials. The right-hand cutting direction and tapered web configuration improve centering and reduce walking on entry. This drill belongs to KENNAMETAL Series B041A-CPG and covers the 3.50 mm to 5.00 mm drill bit size range within that series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance for extended production runs\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust force and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating enhances heat resistance and surface hardness at the cutting edge\u003c\/li\u003e\n\u003cli\u003eStub flute length (24.00 mm) and short OAL (66.00 mm) minimize deflection in close-tolerance setups\u003c\/li\u003e\n\u003cli\u003eTapered web design improves self-centering and chip flow\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures consistent dimensional standards for toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series B041A-CPG stub-length carbide drill for use in standard straight-shank toolholders accepting a 6.00 mm shank diameter.

Ensure the spindle and toolholder are powered down and fully stopped before inserting or removing the bit. Confirm the 6.00 mm shank seats fully and is clamped securely in a compatible collet or chuck before operation. Coolant-through is not supported on this model; use external coolant or cutting fluid appropriate to the workpiece material and cutting speed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 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\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: 17.00 mm (0.6693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.66 mm (0.0258 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\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\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\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\u003eWeight\u003c\/strong\u003e: 0.44 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: 4150193\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728474767666,"sku":"4150193","price":82.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4650f02fedae9b362718feea34a4493.jpg?v=1788691798","url":"https:\/\/voomisupply.com\/products\/kennametal-4150193-carbide-drill-bit-4mm-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
