Accupro 95170365 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 95170365 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard alloy materials. Built on the VS Series platform, it features a 3/16-inch (0.1875 inch) cutting diameter and a 0.0300-inch corner radius that reduces stress concentration at the cutting edge, extending tool life in demanding applications. The 4-flute geometry with variable index and variable helix minimizes chatter and improves surface finish at higher feed rates. An AlCrTiN PVD coating provides thermal resistance and hardness at elevated cutting temperatures. Licensed machinists and CNC programmers specify this tool for finish milling, slotting, and profiling operations where edge integrity matters.

This end mill is suited for use on CNC machining centers and manual knee mills running ferrous alloys, stainless steels, hardened steels, and similar difficult-to-machine materials. The centercutting design allows both plunge and peripheral cutting. With a 5/16-inch length of cut and a 2-inch overall length, it is configured for short-reach applications where rigidity and runout control are priorities. The 3/16-inch straight cylindrical shank with h6 tolerance ensures accurate seating in precision collets and end mill holders.

Key Features

• 0.0300-inch corner radius reduces edge chipping and extends tool life in hard materials
• AlCrTiN PVD coating provides high-temperature hardness and oxidation resistance
• Variable index and variable helix geometry suppress vibration and chatter
• Centercutting capability allows direct plunge entry without pre-drilling
• Micrograin solid carbide construction delivers consistent edge sharpness
• Right-hand cut, right-hand flute spiral for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-specification solid carbide corner radius end mill for CNC machining centers and manual mills accepting a 3/16-inch straight cylindrical shank with h6 tolerance and standard collet or end mill holder tooling.

Installation Notes

Installation should be performed by qualified machinists following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully in a clean, undamaged collet or end mill holder and torque the retention nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before commencing cuts, as the maximum TIR for this tool is 0.0058 inches.
