Built to DIN 6537K standards, this Size 29 (0.1360 inch) bit features a 140-degree point angle that promotes accurate entry and reduces thrust force in hard or abrasive workpiece materials. The TiN-coated tip extends edge life under high-cycle conditions. With a 2-flute regular spiral geometry and a tapered web configuration, chip evacuation stays consistent across the 0.7874-inch flute length. Machinists and tool-and-die professionals specify this series for short-hole drilling where rigidity and dimensional accuracy are critical.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for CNC machining centers, drill presses, and screw machines operating on ferrous metals, hardened steels, cast iron, and similar materials where solid carbide tooling is preferred over high-speed steel. The straight cylindrical shank measures 0.2362 inches in diameter and 1.4173 inches in length, providing positive grip in standard collet chucks and drill holders. Its stub-length geometry minimizes deflection in short-reach applications. Series B041A-CPG is specified for production drilling where consistent hole tolerances and tool life are required across high-volume runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eTiN coating on tip extends cutting-edge life under repeat-cycle conditions\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral with tapered web promotes efficient chip flow\u003c\/li\u003e\n\u003cli\u003eStub-length design maximizes stiffness and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inches ensures consistent hole sizing\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for standardized dimensional control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production tooling option within the KENNAMETAL Series B041A-CPG screw machine length drill line.

Ensure the collet or chuck is clean and undamaged before seating the straight shank to maintain runout tolerances. Do not exceed the maximum drilling depth of 0.5512 inches per pass without confirming chip clearance and coolant strategy for the specific workpiece material. Refer to KENNAMETAL cutting data recommendations and shop-floor speeds-and-feeds guidelines for optimal tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 29\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1360 inches\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: TiN (Tip)\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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5512 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4409 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0221 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\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\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: 4150183\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732333560114,"sku":"4150183","price":82.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32c8cee59bc330dfbc7229e89df28d80.jpg?v=1788741733","url":"https:\/\/voomisupply.com\/products\/kennametal-4150183-drill-bit-size-29-solid-carbide-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
