It carries a 0.0150-inch corner radius on a 1\/4-inch diameter cutter with five flutes and a 38-degree helix angle, delivering a balance of surface finish and material removal rate in a single-end configuration. The TiAlN\/THL dual coating, designated WJ30TF in the Walter proprietary system, provides thermal resistance and wear protection in high-speed cutting environments. Licensed machinists and CNC operators specify this tool for roughing and finishing passes where edge integrity on difficult alloys is critical.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 1\/4-inch straight-cylindrical shank toolholders with an h6 shank diameter tolerance, making it compatible with collet chucks, hydraulic holders, and shrink-fit systems commonly found in CNC machining centers. The 3\/4-inch length of cut and 2-1\/2-inch overall length suit it for shallow-to-moderate-depth pockets, profiling, and contouring operations on steel and ferrous alloys. The 1.3976-inch reach length provides clearance for light-depth work on stepped or offset features. This tool is part of the Walter MA230.A-5-R-C series and is cataloged under manufacturer number MA230.6.35A5D038E-WJ30TF.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and exotic alloy cutting\u003c\/li\u003e\n\u003cli\u003eTiAlN\/THL (WJ30TF) coating provides high-temperature oxidation resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eFive-flute geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eh6 shank tolerance ensures precise fit in collet and hydraulic toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills with 1\/4-inch straight-cylindrical collet or hydraulic toolholders.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended insertion depth in the toolholder and torque the collet nut or clamping mechanism per the toolholder manufacturer's specifications. Verify runout with a dial indicator after clamping before initiating a cutting program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.3976 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\/THL (WJ30TF)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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\u003eCentercutting\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Cast Iron (K), Stainless Steel (M), Superalloys and Titanium (S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MA230.A-5-R-C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Catalog Number\u003c\/strong\u003e: MA230.6.35A5D038E-WJ30TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.39 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: 8415105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67916220563762,"sku":"8415105","price":140.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a22927176a1132bb011937421d910391_f9bcec99-4947-41ee-bbf2-696522acd394.jpg?v=1791256823","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-8415105-corner-radius-end-mill-1-4in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
