Built to DIN 6537K standards, it features a 140-degree split point for accurate entry and reduced thrust, a multilayer TiAlN coating at the tip for extended tool life under heat, and coolant-through capability to maintain cutting performance in deep-hole and high-speed applications. At 11\/64 inch (0.1719 inch) diameter with a 2.5984-inch overall length, this stub-length bit offers increased rigidity over jobber-length equivalents. Licensed HVAC, mechanical, and industrial machinists working with CNC or manual screw machine setups will find this bit suited to tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in screw machine and production drilling operations where stub-length rigidity is required. The straight cylindrical shank at 0.2362 inch (6.00 mm) diameter is compatible with standard drill chucks and collet systems. The regular spiral flute geometry handles chip evacuation efficiently in through-coolant setups. A maximum drilling depth of 0.6693 inch (17.00 mm) makes this appropriate for short, precise bores in metal workpieces typical of automated machining cycles. It is sold individually and is suited to shops running Series B051A-CPG tooling programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance beyond high-speed steel alternatives\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces walking and lowers axial thrust on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design channels fluid directly to the cutting zone for heat control and chip flushing\u003c\/li\u003e\n  \u003cli\u003eTiAlN tip coating extends cutting life in ferrous and hard alloy materials\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures dimensional consistency and interchangeability\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration and regular spiral flutes support efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification stub drill for use in CNC machining centers, screw machines, and manual drill presses equipped with chucks or collets accepting a 0.2362-inch straight cylindrical shank.

Ensure the machine spindle and chuck or collet are clean and properly tightened before running. Verify coolant-through supply pressure and flow are appropriate for the machine before engaging the cut. Do not exceed the rated maximum drilling depth of 0.6693 inch per cycle without retracting for chip clearance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/64 inch (0.1719 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5984 inches (66.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.9449 inches (24.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6693 inches (17.00 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: 0.0283 inches (0.72 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\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\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\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: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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: B051A-CPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 4151124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51752104984882,"sku":"4151124","price":125.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/98e3d212a774fdc8126cd95ec9f444cc.jpg?v=1788925872","url":"https:\/\/voomisupply.com\/products\/kennametal-4151124-screw-machine-drill-bit-11-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
