Built from solid carbide and coated with a multilayer TiAlN finish, this bit delivers heat resistance and wear life well beyond standard high-speed steel tooling. It measures 0.2656 inches (17\/64 inches) in diameter with a 140-degree point angle for aggressive, self-centering entry. The overall length is 4 inches (105 mm), and the flute length runs 2.6378 inches (67 mm). Licensed machinists, tool-and-die technicians, and production operators working in ferrous and hardened materials rely on this geometry for consistent, repeatable results.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited to CNC machining centers, drill presses, and manual mills where straight-shank tooling is required. The Series B053A-CPG designation places it in a product family optimized for taper-length reach in confined bores and deep-feature work. With a maximum drilling depth of 2.2441 inches (57 mm) and a flute-to-diameter ratio of 8xD, it handles moderate-to-deep hole cycles without excessive tool deflection. Coolant-through capability makes it well-matched to high-feed, high-spindle-speed programs where chip evacuation and thermal management are critical to surface finish and tool life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with multilayer TiAlN coating for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle for fast, self-centering penetration\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-feed cycles and deep-hole chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.3150 inches (8 mm) diameter for standard collet or chuck mounting\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute, right-hand cut, tapered web configuration per DIN 6537K\u003c\/li\u003e\n  \u003cli\u003eMaterial grade KC7325 for performance in a broad range of workpiece materials\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 within the KENNAMETAL B053A-CPG series, compatible with any straight-shank toolholder or drill chuck accepting an 8 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and serviced by qualified machinists or CNC setup technicians. Before changing or inspecting the bit, confirm the spindle is fully stopped and the machine is in an energy-isolated state per your facility lockout\/tagout procedure. Seat the straight shank fully in the collet or chuck and verify runout before beginning a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coolant configuration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B053A-CPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 17\/64 inches (0.2656 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KC7325\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multilayer TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (105 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.6378 inches (67 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches (8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.2441 inches (57 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0447 inches (1.14 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 8xD\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches (-0.015 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\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 4149652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744234864946,"sku":"4149652","price":279.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cd08b2d5d544bfb28965121c0413198_4bf8a96d-7958-4674-a43c-308904840263.jpg?v=1788855229","url":"https:\/\/voomisupply.com\/products\/kennametal-4149652-taper-length-drill-bit-17-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
