Sized at wire gauge 32 (0.1160 inches decimal equivalent), it features a 140-degree standard point angle for self-centering entry and reduced thrust. The multilayer TiAlN coating at the tip extends tool life in abrasive and hard materials. With an overall length of 2.2835 inches (58.00 mm) and a flute length of 0.6693 inches (17.00 mm), this stub-length bit delivers maximum rigidity and minimized deflection in close-tolerance work. It is manufactured to DIN 6537K specification.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for CNC machining centers, drill presses, and screw machines operating in production environments. The stub length format is preferred when drilling short-depth holes requiring tight dimensional control, particularly in ferrous metals, hardened steels, cast iron, and similar difficult-to-machine materials. The straight cylindrical shank at 0.1575 inches (4.00 mm) diameter seats securely in standard drill chucks and collets. Maximum drilling depth is 0.4724 inches (12.00 mm). Typical users include machinists and CNC operators in general manufacturing and job shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides superior hardness and heat resistance compared to high-speed steel\u003c\/li\u003e\n  \u003cli\u003eTiAlN tip coating extends cutting edge life in abrasive and high-temperature drilling conditions\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle reduces thrust and improves self-centering on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eStub length design maximizes rigidity and minimizes deflection for close-tolerance hole quality\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration and regular spiral flutes support efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 6537K specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for use in CNC machining centers, drill presses, and screw machines equipped with drill chucks or collets accepting a 0.1575-inch straight cylindrical shank. Belongs to KENNAMETAL Series B041A-CPG.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or CNC operators familiar with cutting tool setup and safe machine operation. Ensure the machine spindle is fully stopped and locked out before inserting or removing the drill bit from the chuck or collet. Verify chuck or collet runout is within acceptable tolerances prior to drilling, as excessive runout accelerates wear on carbide tooling. Do not exceed the maximum drilling depth of 0.4724 inches without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1160 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: TiAlN (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\u003eOverall Length\u003c\/strong\u003e: 2.2835 inches (58.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.6693 inches (17.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1575 inches (4.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1024 inches (28.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.4724 inches (12.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0187 inches (0.47 mm)\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\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\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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches\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\u003eSeries\u003c\/strong\u003e: B041A-CPG\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: 23241635\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: 4151661\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731016581426,"sku":"4151661","price":94.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8936a991ddf49b382c80c943c63c1d12.jpg?v=1788725898","url":"https:\/\/voomisupply.com\/products\/kennametal-4151661-drill-bit-size-32-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
