Accupro 95168669 Corner Radius End Mill 3/4in 4 Flute

Product Description

The ACCUPRO 95168669 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and high-hardness materials. It features a 3/4 inch cutting diameter with a 0.1200 inch corner radius, a 4-flute right-hand spiral configuration, and an AlTiN coating that extends tool life in high-heat cutting environments. The overall length is 4 inches with a 1-5/8 inch length of cut. Variable helix geometry reduces chatter and improves surface finish. This is a single-end, centercutting tool suited for machinists and toolroom operators running CNC mills or manual vertical mills.

This end mill is well suited for slotting, profiling, and contouring operations where a radiused corner is required to reduce stress concentrations or match a part geometry. The micrograin carbide substrate and AlTiN coating make it a strong choice for cutting alloy steels, stainless steels, and hardened materials in both shop and production environments. The 3/4 inch shank diameter mates directly with standard ER or side-lock toolholders at that bore size.

Key Features

• 0.1200 inch corner radius reduces stress risers and matches radiused pocket geometry
• AlTiN coating provides oxidation resistance and extended tool life in ferrous materials
• 4-flute variable helix design minimizes chatter and improves surface finish
• Centercutting geometry allows plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate for rigidity and edge retention
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard 3/4 inch bore toolholders used in CNC machining centers and manual vertical mills requiring a corner radius end mill configuration.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the toolholder and torque the retention mechanism to the toolholder specification. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates edge wear on carbide tooling.
