Accupro 95170930 Corner Radius End Mill 3/8 in Zrn

Product Description

The ACCUPRO 95170930 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide and coated with ZrN (Zirconium Nitride), it delivers extended tool life and heat resistance in demanding cutting applications. The 3/8-inch diameter cutter features a 3-flute, right-hand spiral geometry with a 37-degree helix angle and a 0.015-inch corner radius that reduces chipping at part edges. Centercutting capability allows plunge entry directly into the workpiece. Installed by machinists and CNC operators in job shops, tool rooms, and production environments.

This end mill is suited for finish and semi-finish milling of ferrous and non-ferrous metals where edge integrity and surface quality are priorities. The stub-length-of-cut design at 1/2 inch promotes rigidity, reducing deflection in tight-tolerance applications. The single-end, 3/8-inch shank fits standard ER and end mill holders common on vertical machining centers and manual knee mills. The 4-inch overall length provides clearance for most standard setups without excessive overhang.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention
• ZrN coating reduces friction and extends tool life in steel and stainless applications
• 0.015-inch corner radius reduces stress concentration and edge chipping on finished parts
• 3-flute, right-hand cut with 37-degree helix for efficient chip evacuation
• Centercutting design enables direct plunge milling without pre-drilled entry
• Stub length of cut (1/2 inch) maximizes rigidity and minimizes deflection

Compatibility

Designed for use in standard 3/8-inch end mill holders and ER collet chucks on CNC machining centers and manual vertical mills requiring a single-end corner radius tool.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before tool changes. Secure the shank in a properly sized collet or end mill holder to the torque specification listed by the toolholder manufacturer. Avoid excessive overhang beyond the holder to maintain the rigidity gains provided by the stub-length geometry.
