Accupro 95168281 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 95168281 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 0.2500 inch mill diameter with a 0.0150 inch corner radius, a 4-flute spiral geometry, and a stub-length 0.3750 inch length of cut. The AlTiN coating provides thermal resistance and wear protection, making this tool well-suited for dry or semi-dry cutting in ferrous and hard materials. Right-hand cutting and right-hand flute direction are standard. The variable helix and centercutting capability allow for plunge entry and improved chip evacuation. This end mill is used by machinists and CNC operators in job shops, tool rooms, and production environments.

The 95168281 is built for use in CNC machining centers and manual knee mills handling ferrous metals, stainless steels, and hardened materials where corner radii are required to reduce stress concentrations at part features. The stub length configuration provides rigidity in tight setups. With a 1/4 inch shank diameter, it fits standard collet systems and end mill holders commonly found in light to medium-duty machining setups. A single-end design means the tool is replaced rather than reversed when worn.

Key Features

• Solid micrograin carbide construction for wear resistance and edge retention
• AlTiN coating extends tool life in high-heat cutting conditions
• 0.0150 inch corner radius reduces corner chipping and part stress risers
• Variable helix flute geometry improves chip flow and reduces chatter
• Centercutting design permits direct plunge entry
• Right-hand cut, right-hand spiral single-end configuration

Compatibility

Designed for use in standard 1/4 inch collet chucks and end mill holders on CNC machining centers and manual milling machines requiring a stub-length corner radius end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and power is locked out before installing or removing tooling. Seat the shank fully into the collet or holder to the recommended gauge line and torque the retention system per the tool holder manufacturer specification. Inspect the cutting edges for chips or coating damage before use.
