Accupro 12183341 Corner Radius End Mill 5/8in 4 Flute Carbide

Product Description

The ACCUPRO 12183341 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/8 inch diameter with a 0.03 inch corner radius, delivering controlled edge geometry that reduces chipping and extends tool life compared to square-end alternatives. The 4-flute, right-hand spiral configuration provides efficient chip evacuation and a smooth surface finish. With a 3 inch length of cut and 6 inch overall length, this is classified as an extra-long tool suited for deep-cavity and extended-reach milling applications. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.

This end mill is appropriate for milling steel, alloys, and similar ferrous and non-ferrous materials where a radiused corner profile is required to reduce stress concentrations in part geometry. The centercutting design allows for plunge entry, making it versatile for slotting, profiling, and pocketing operations. The bright uncoated finish is typical for general-purpose machining where coatings are not required or where post-coat regrinding is anticipated. The extra-long configuration is well suited to deep-cavity mold work, die making, and fixturing applications where standard-length tooling cannot reach.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in demanding cuts
• 0.03 inch corner radius reduces stress risers and edge chipping on finished workpiece geometry
• 4-flute right-hand spiral design balances chip load and surface finish in full-slot and peripheral milling
• Centercutting capability allows direct plunge entry without a pre-drilled pilot hole
• Extra-long 6 inch overall length with 3 inch length of cut for deep-cavity and extended-reach applications
• Bright uncoated finish suitable for general-purpose use and compatible with regrinding services

Compatibility

Designed as an OEM-style solid carbide corner radius end mill compatible with standard 5/8 inch ER, side-lock, or hydraulic toolholders used on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with tool holding and runout requirements. Ensure the toolholder is clean and free of debris before seating the shank, and confirm proper torque on the retention mechanism per the toolholder manufacturer's specifications. Verify spindle runout is within acceptable limits before engaging the cut, as excessive runout accelerates wear on carbide tooling. Always follow applicable shop safety protocols and machine guarding requirements when changing tooling.
