Built on the MC388 series platform, it features a 5 mm cutting diameter, a 1 mm corner radius, and a TiAlSiN PVD coating that extends tool life in high-heat, high-speed cutting environments. With three right-hand helical flutes and a high helix style, it balances chip evacuation with surface finish across both roughing and finishing passes. The centercutting geometry allows plunge entry, giving machinists flexibility in toolpath strategy. This tool is intended for use with a standard toolholder and fits shops running precision CNC milling operations.\u003c\/p\u003e\n\u003cp\u003eThe 7254996 is suited for milling steel and hard materials in production and job-shop environments. Its extended-reach geometry, with a 21 mm reach length, provides clearance in deep-pocket and wall-clearance scenarios where a standard-length tool would make contact with the workpiece or fixture. The coarse pitch and right-hand cutting direction are optimized for conventional and climb milling on CNC machining centers. The straight-cylindrical shank with h6 tolerance ensures a secure, repeatable grip in collet-style and hydraulic toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlSiN PVD coating resists heat and wear in steel and hard material cutting\u003c\/li\u003e\n  \u003cli\u003e1 mm corner radius reduces stress concentration at cutting corners and improves edge life\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 21 mm provides clearance for deep-pocket milling operations\u003c\/li\u003e\n  \u003cli\u003eFine grain solid carbide substrate maintains rigidity and edge sharpness at elevated feeds\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with right-hand flute direction for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard collet, hydraulic, or shrink-fit toolholders accepting a 6 mm straight-cylindrical shank.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tools. Verify shank seating depth and runout with a dial indicator before beginning a production run. Do not exceed the tool manufacturer's recommended cutting parameters for speed, feed, and depth of cut when machining hard materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5 mm (0.1969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13 mm (2.4016 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 57 mm (approximately 2.24 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 21 mm (0.5120 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlSiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSubstrate Material\u003c\/strong\u003e: Solid Carbide, Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MC388\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.56 x 0.47 x 0.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: WALTER-PROTOTYP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7254996\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67907303342386,"sku":"7254996","price":143.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92c4d630a867c00572c363f2b154d046.jpg?v=1791176791","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-7254996-corner-radius-end-mill-5mm-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
