Accupro 12180644 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The ACCUPRO 12180644 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 3/4-inch diameter with a 0.0600-inch corner radius and 4 flutes arranged in a right-hand spiral with variable index geometry to reduce harmonic chatter. The AlTiN coating provides heat resistance and extended tool life in high-speed dry or near-dry cutting conditions. With a 40-degree helix angle and centercutting capability, this end mill handles both plunge and contour operations. Machinists and tool-and-die shops running CNC machining centers are the primary users.

This end mill suits applications in mold making, die finishing, and general precision machining where a blended corner radius is required to reduce stress concentrations in machined pockets and profiles. The 1-5/8-inch length of cut and 4-inch overall length provide adequate reach for most standard milling setups without excessive tool deflection. It is well suited to job shops and production environments running hardened steels, stainless, and titanium alloys where AlTiN coating performance is most effective.

Key Features

• 0.0600-inch corner radius blends sharp pocket corners to reduce part stress and improve tool life
• AlTiN coating supports high-speed cutting in ferrous alloys, stainless, and titanium with improved heat resistance
• Variable index flute spacing reduces chatter and vibration at elevated feed rates
• 40-degree helix angle promotes efficient chip evacuation and smooth surface finish
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate provides rigidity and edge retention at the 3/4-inch diameter

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining center applications requiring a 3/4-inch shank and 3/4-inch cutting diameter with a 0.0600-inch radius profile.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the 3/4-inch shank in a matching collet, end mill holder, or shrink-fit toolholder and verify runout before cutting. Power down and lock out the spindle before changing tooling per standard machine shop safety practice. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
