Sized at Letter S (0.3480 inches diameter), it features a 140-degree split-point geometry and a multilayer TiAlN coating that extends tool life in abrasive and hard-material applications. The straight cylindrical shank measures 0.3937 inches in diameter, and the overall length is 3.5039 inches. Coolant-through capability supports high-speed drilling operations where heat management is critical. This bit is installed by machinists and tool-and-die professionals on CNC machining centers and drill presses.\u003c\/p\u003e\u003cp\u003eThe 4054510 is suited for short-reach drilling applications where rigidity and runout control matter. The stub flute length of 1.8504 inches and a maximum drilling depth of 1.3780 inches make it appropriate for through-hole and blind-hole work in close-tolerance setups. The 3xD flute-to-diameter ratio and tapered web configuration help with chip evacuation in steel, cast iron, and similar ferrous materials. This bit conforms to DIN 6537K specification, making it a recognized standard in precision machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter S diameter (0.3480 inches) with a tolerance of +0.006 to +0.021 mm for close-tolerance drilling\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating increases heat resistance and extends tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed, high-feed drilling operations\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank (0.3937 inches) fits standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and multi-spindle machines accepting straight-shank drill bits in the 0.3000 to 0.3500 inch diameter range, per DIN 6537K specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or chuck bore matches the 0.3937-inch shank diameter before seating the bit. When using coolant-through capability, confirm the machine coolant system is properly pressurized and that the coolant path is clear before starting the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3480 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5039 inches (89.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.8504 inches (47.00 mm)\u003c\/li\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.3780 inches (35.00 mm)\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5748 inches (40.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0591 inches (1.50 mm)\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 by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN (Multilayer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.3000 to 0.3500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B976A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.156 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: 4054510\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739103920434,"sku":"4054510","price":236.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ade34d285a5cf22b9beea0fa6c5f1095.jpg?v=1788809447","url":"https:\/\/voomisupply.com\/products\/kennametal-4054510-drill-bit-letter-s-0-348-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
