Accupro 95172650 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 95172650 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1/4 inch diameter, a 0.0600 inch corner radius, and four flutes with variable index and variable helix geometry. The AlCrTiN PVD coating provides thermal and wear resistance in demanding cutting environments. With a 3/4 inch length of cut and 2.5 inch overall length, this single-end, centercutting tool handles slotting, profiling, and finishing passes in harder materials. It is installed and operated by machinists and CNC programmers working with vertical or horizontal machining centers.

This end mill is suited for ferrous and hardened materials where a corner radius profile is required to improve corner strength and reduce chipping on the workpiece. The long flute configuration and micrograin carbide substrate support stable cutting at higher speeds and feeds. Typical applications include die and mold work, aerospace components, and precision part manufacturing where controlled corner geometry is critical to part specification.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlCrTiN PVD coating rated for high-heat cutting in ferrous and hardened materials
• Variable index and variable helix flute geometry reduces harmonic vibration during cutting
• 0.0600 inch corner radius for improved edge strength and workpiece corner integrity
• Centercutting capability allows plunge entry into the workpiece
• Right-hand cut and right-hand spiral flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 1/4 inch straight cylindrical shank with h6 shank diameter tolerance.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder runout and collet torque specifications per the machine manufacturer guidelines. Verify TIR does not exceed 0.0044 inch at the cutting edge before beginning a production run. Ensure the spindle is fully stopped and the machine is in a safe locked-out state before inserting or removing the tool. Do not use this end mill beyond its rated length of cut of 3/4 inch to avoid deflection and premature tool failure.
