Built to DIN 6537K specification, it features a 140-degree point angle and a multilayer TiAlN coating that extends tool life under demanding cutting conditions. The bit measures 0.0938 inches (3\/32 inches) in diameter with an overall length of 2.2835 inches (58.00 mm). It runs in a right-hand, regular spiral flute configuration and uses a straight cylindrical shank. This tool is intended for use by machinists and tool-and-die professionals in CNC and manual screw machine operations where stub-length rigidity is required.\u003c\/p\u003e\n\u003cp\u003eThe 4151646 fits applications requiring compact drill length and high radial stiffness, such as short-hole drilling in metals on screw machines, machining centers, and drill presses. The stub-length body reduces deflection at small diameters. The 3xD flute-to-diameter ratio supports chip evacuation in shallow holes. No coolant-through capability is present, so external coolant or dry cutting conditions apply. The Series B041A-CPG designation identifies the full product family within the KENNAMETAL catalog.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eTiAlN multilayer coating extends tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length reduces deflection compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration supports point strength and regrindability\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard ER collets and drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement within the KENNAMETAL Series B041A-CPG product family.

Ensure the spindle is fully de-energized and locked out before changing tooling. Seat the shank fully and concentrically in the collet or chuck to prevent runout at this small diameter. No coolant-through ports are present; direct external coolant flow to the cutting zone or verify suitability for dry cutting before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/32 inches (0.0938 inches)\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 Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0149 inches (0.38 mm)\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN Multilayer (TiN Tip)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 4151646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733105213746,"sku":"4151646","price":99.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acc644481df5fd573118b26c1ebdaf84.jpg?v=1788751416","url":"https:\/\/voomisupply.com\/products\/kennametal-4151646-screw-machine-drill-bit-3-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
