Accupro 2500533 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 2500533 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled corner radius profile. With a 3/16 inch (0.1875 inch) diameter and a 0.010 inch corner radius, this single-end, center-cutting tool is built for high-performance material removal in ferrous and hardened materials. The AlCrTiN coating provides thermal resistance and extended tool life at elevated cutting speeds. A 38-degree variable index helix and chipbreaker geometry reduce chatter and improve chip evacuation. Machinists and tool-and-die professionals working on CNC machining centers are the primary users of this tool.

This end mill is suited for slot milling, profiling, and finishing passes in applications where a defined corner radius is required to reduce stress concentration in machined parts. The 4-flute, right-hand cutting and right-hand flute configuration makes it appropriate for general-purpose milling in steel, stainless, and similar materials. The 5/8 inch length of cut (LOC) and 2-1/2 inch overall length (OAL) support reach into moderate-depth pockets and channels. The micrograin carbide substrate maintains edge integrity under demanding cut conditions.

Key Features

• AlCrTiN coating for high heat resistance and extended tool life
• 0.010 inch corner radius reduces stress risers in finished parts
• Chipbreaker geometry improves chip flow and reduces cutting forces
• Variable index flute spacing minimizes harmonic vibration and chatter
• Center-cutting design allows direct plunge entry
• Micrograin solid carbide substrate for sharpness retention

Compatibility

Designed as an OEM-style replacement and standard-fitment end mill for CNC machining centers and manual mills accepting a 3/16 inch straight shank toolholder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the collet or toolholder. Confirm runout with a dial indicator after clamping to avoid premature edge wear. Follow the machine tool manufacturer guidelines for speed and feed parameters appropriate to the workpiece material and depth of cut.
