Accupro 95169778 Corner Radius End Mill 1/4 in 7 Flute

Product Description

The ACCUPRO 95169778 is a solid carbide corner radius end mill designed for precision milling operations in demanding machining environments. It features a 1/4 inch diameter with a 0.020 inch corner radius and a 1/2 inch length of cut, making it well suited for finishing passes and contour work where controlled edge geometry is critical. The 7-flute design increases chip load capacity and improves surface finish at higher feed rates. An AlCrTiN coating provides thermal resistance and wear protection, extending tool life in ferrous and hardened materials. Overall length is 2 inches with a 1/4 inch straight cylindrical shank.

This end mill is used in CNC milling applications across job shops, tool rooms, and production machining facilities. It is appropriate for finish milling of slots, pockets, and profiles where a corner radius is required to reduce stress concentration and meet part geometry tolerances. The non-centercutting design means it is intended for side milling and peripheral cuts rather than plunge entry. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle setups.

Key Features

• 7-flute solid carbide construction for high feed rates and improved surface finish
• AlCrTiN coating for thermal and wear resistance in ferrous and hardened materials
• 0.020 inch corner radius reduces edge chipping and stress concentration at corners
• 38-degree helix angle promotes efficient chip evacuation during peripheral milling
• Non-centercutting design suited for side milling and profile operations
• Micrograin carbide grade for edge retention in tight-tolerance work

Compatibility

Designed as an OEM-style replacement and production end mill for CNC machining centers accepting a 1/4 inch straight cylindrical shank toolholder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the toolholder collet or end mill holder is clean and free of debris before seating the shank. Verify spindle speed, feed rate, and depth of cut parameters are appropriate for the workpiece material before engaging the cut. Do not use this tool for plunge cutting, as it is a non-centercutting design.
