Built to DIN 6537K standards, it features an 8.20 mm cutting diameter, a 140-degree point angle for self-centering on curved or angled surfaces, and a multilayer TiAlN coating for extended tool life at elevated cutting temperatures. Coolant-through capability supports chip evacuation and heat management during deep cuts. With an overall length of 3.5039 inches and a straight cylindrical shank, this bit mounts in standard drill chucks and collet systems without special adapters.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for high-speed drilling operations on ferrous and non-ferrous metals, stainless steel, and hardened alloys in CNC machining centers, drill presses, and screw machine setups. The stub length design increases rigidity and reduces deflection in short-reach applications. It is commonly installed by machinists, tool-and-die tradespeople, and CNC operators working in production environments where consistent hole diameter tolerance is critical. The 2-flute regular spiral configuration promotes efficient chip flow in through-hole and blind-hole drilling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eTiAlN multilayer coating (TiN tip) extends tool life in ferrous metal applications\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle self-centers and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design flushes chips and controls heat at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration maintains strength along the flute length\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures dimensional interchangeability with other DIN-standard tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement drill bit in the KENNAMETAL Series B051A-CPG.

Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Verify chuck or collet runout before securing the shank to maintain diameter tolerance at the cutting edge. When using coolant-through capability, confirm coolant pressure and flow rate are appropriate for the application before beginning the drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.20 mm (0.3228 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\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\u003eOverall Length\u003c\/strong\u003e: 89.00 mm (3.5039 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47.00 mm (1.8504 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.00 mm (1.3780 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm (1.5748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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: -0.015 to 0.000 mm (-0.0006 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\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.5 inches (L) x 1.5 inches (W) x 1.5 inches (H)\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: 4151177\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740349497650,"sku":"4151177","price":180.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff093885ce5e245f584cc2c706f18eec.jpg?v=1788824479","url":"https:\/\/voomisupply.com\/products\/kennametal-4151177-carbide-drill-bit-8-20mm-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
