Part of the MC251 series, it carries a TiAlN (PVD) coating under the proprietary WK40RC material grade designation. The 6mm mill diameter pairs with a 0.50mm corner radius to reduce chipping at the cutting edge during both roughing and finishing passes. With a variable helix flute geometry and extended reach design, this single-end head is built for situations where tool rigidity and chip evacuation are both critical. It mounts to compatible straight-cylindrical toolholders and is manufactured to h9 mill diameter and h5 shank diameter tolerances.\u003c\/p\u003e\u003cp\u003eThis end mill head is suited for machining stainless steel and high-temperature alloys in precision manufacturing environments. The extended reach and 13mm length of cut make it applicable in pocketing, contouring, and profiling operations where clearance is limited. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups. It is intended for use with compatible toolholders and is appropriate for shops running aerospace, medical, or industrial component work where tight tolerances and difficult materials are routine.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN PVD coating (WK40RC grade) for heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eVariable helix flute geometry promotes chip evacuation and reduces chatter during cut\u003c\/li\u003e\n\u003cli\u003e0.50mm (0.0390 inch) corner radius reduces edge chipping on stainless steel and superalloy workpieces\u003c\/li\u003e\n\u003cli\u003eExtended reach design with 21mm reach length for clearance in deep-pocket applications\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, supporting plunge and ramp entry moves\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, single end configuration for standard CNC milling spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with straight-cylindrical toolholders compatible with a 6mm shank diameter. Catalog reference MC251-06.0-A4B100. Primary workpiece materials are stainless steel (ISO material code M) and superalloys and titanium (ISO material code S).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician following the toolholder manufacturer's clamping specifications. Ensure the toolholder collet or chuck bore is clean and free of debris before seating the shank. Confirm runout is within acceptable limits using a dial indicator before beginning the cut. Do not exceed the rated reach depth without verifying adequate tool rigidity for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 6.00mm (0.2360 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13.00mm (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.50mm (0.0390 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 57.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 21.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (PVD)  -  WK40RC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Variable Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium (ISO Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MC251\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.053 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-PROTOTYP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6814324\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67912175386930,"sku":"6814324","price":140.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df3633bd7cd1c3dae5736f37ad514091.jpg?v=1791228733","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-6814324-corner-radius-end-mill-6mm-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
