Built to DIN 6537K standards, this 2.60 mm diameter bit features a 140-degree point angle for reduced thrust and improved centering on entry. The multilayer TiAlN coating on the tip extends tool life in abrasive and high-temperature cutting conditions. With an overall length of 58.00 mm and a flute length of 17.00 mm, the compact stub geometry provides maximum rigidity and reduced deflection in CNC and manual drill press setups. Installed by machinists and tool-and-die professionals working in close-tolerance production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for short-depth drilling operations where rigidity matters more than reach. The 3xD flute-to-diameter ratio and tapered web configuration support chip evacuation in steel, cast iron, and similar ferrous workpiece materials. The straight cylindrical shank, measuring 4.00 mm in diameter and 28.00 mm in length, seats securely in standard collets and drill chucks without modification. Maximum drilling depth is 12.00 mm, making this bit appropriate for shallow, precision holes in production runs, fixture work, and component manufacturing. The right-hand cutting direction and regular spiral flute geometry are compatible with standard spindle rotation on most machine tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in production drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n  \u003cli\u003eTiAlN tip coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures dimensional consistency for replacement use\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration promotes chip clearing in blind and through-hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production cutting tool in the KENNAMETAL Series B041A-CPG. Fits standard straight-shank collets and drill chucks accepting a 4.00 mm shank diameter. Suitable for use on CNC machining centers, drill presses, and manual machine tools with right-hand spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and CNC operators. Power down and lock out the spindle before changing tooling. Seat the shank fully in the collet or chuck and verify runout before beginning a production run. Solid carbide tooling is brittle and should not be used in applications with significant lateral loading or interrupted cuts beyond the tool's rated capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.60 mm (0.1024 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 58.00 mm (2.2835 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 17.00 mm (0.6693 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 28.00 mm (1.1024 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 12.00 mm (0.4724 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: 0.42 mm (0.0164 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\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\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\u003eFlute-to-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\u003c\/strong\u003e: TiAlN (Tip)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches (-0.014 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\u003eWeight\u003c\/strong\u003e: 0.02 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: 4151652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742229430578,"sku":"4151652","price":95.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/027550a92e9fb7c9c67a753ee7e2e1a8_242245f6-fe87-41f4-8ef9-8f11018bc62b.jpg?v=1788836039","url":"https:\/\/voomisupply.com\/products\/kennametal-4151652-screw-machine-drill-bit-2-60mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
