Accupro 95168569 Corner Radius End Mill 3/8 in 5 Flute

Product Description

The ACCUPRO 95168569 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous metals. It measures 3/8 inches in diameter with a 0.0200-inch corner radius and features five flutes in a right-hand spiral configuration with a variable helix for reduced chatter and improved chip evacuation. The AlTiN coating provides high heat resistance, making it well suited for dry or semi-dry cutting at elevated speeds. Overall length is 4 inches with a 1/2-inch length of cut. This tool is installed and operated by machinists and CNC tooling technicians working in precision manufacturing environments.

This end mill is used in machining centers and CNC milling machines where corner radius profiles are required to reduce stress concentrations at part features. The single-end, centercutting design allows for plunge entry as well as peripheral and slot milling. The extended reach configuration, with a reach length of 2.125 inches and a neck diameter of 0.3375 inches, makes it suitable for accessing deep or recessed features. Micrograin carbide construction supports high-speed cutting in hardened steels, stainless, and titanium alloys where tool life and dimensional consistency are critical.

Key Features

• 0.0200-inch corner radius reduces stress risers on finished part profiles
• AlTiN coating delivers high-temperature resistance for dry and high-speed cutting
• Variable helix flute geometry reduces harmonics and chatter during long-reach operations
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Extended reach at 2.125 inches with reduced neck diameter of 0.3375 inches for deep-feature access
• Micrograin solid carbide construction maintains edge integrity in difficult-to-machine materials

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC milling machine spindles accepting a 3/8-inch straight shank end mill holder or collet.

Installation Notes

Installation and tool changes must be performed by qualified machinists with the machine in a full stop and lockout-tagout procedures in place. Secure the 3/8-inch shank in a compatible collet, shrink-fit holder, or hydraulic chuck to the holder manufacturer's specified pull-out torque range. Inspect the cutting edges and coating for chips or wear before each use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.
