Accupro 95170094 Corner Radius End Mill 7/16 in 4 Flute

Product Description

The ACCUPRO 95170094 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hardened materials. The 7/16-inch diameter cutter features a 0.0200-inch corner radius, four flutes, and an AlCrTiN coating that provides high heat and wear resistance at elevated cutting speeds. With a 38-degree variable-index helix and right-hand flute direction, this end mill is built for stable, chatter-resistant cuts in demanding machining environments. It is a single-end, centercutting design, allowing plunge entry directly into the workpiece. Machinists and CNC operators working in job shops, tool rooms, and production environments will find this tool suited to finishing and semi-finishing passes on steel, stainless, and hardened alloys.

This end mill is used in vertical and horizontal milling applications where corner radius geometry is required to reduce stress concentrations at the base of a shoulder or pocket. The 5/8-inch length of cut and 2-1/2-inch overall length make it appropriate for shallow-to-medium depth pocketing and profiling operations. The micrograin carbide substrate combined with AlCrTiN coating supports dry or minimum-quantity lubrication machining strategies common in high-production environments.

Key Features

• AlCrTiN coating for extended tool life in high-temperature cutting conditions
• Solid micrograin carbide substrate for rigidity and edge retention
• 0.0200-inch corner radius reduces edge chipping and stress at pocket corners
• Variable index flute spacing minimizes chatter and vibration during aggressive passes
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand spiral for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 7/16-inch collet or end mill holders used in CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a properly sized collet or end mill holder and torque to the tool holder manufacturer's specification. Ensure the spindle and machine are fully powered down and locked out before changing tooling. Verify runout with a dial indicator after installation to confirm proper seating before initiating a cut.
