Accupro 313192 Corner Radius End Mill 3/8 in Solid Carbide

Product Description

The ACCUPRO 313192 is a single-end, corner radius end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide, it delivers the hardness and wear resistance required for demanding cuts in ferrous and non-ferrous materials. The ZrN (zirconium nitride) coating reduces friction and extends tool life at elevated cutting temperatures. With a 3/8 inch mill diameter, a 1 inch length of cut, and a 0.020 inch corner radius, this tool produces smooth floor finishes while protecting corners from chipping. It is installed and operated by machinists and CNC tool-and-die professionals.

This end mill is suited for milling slots, pockets, and contours where a small corner radius is required to reduce stress concentration at part edges. The centercutting geometry allows plunge entry directly into workpiece material without pre-drilling. Right-hand flute direction and right-hand cutting direction make it compatible with standard vertical machining centers and manual knee mills. Its regular length profile keeps it rigid during high-helix cuts at 45 degrees, minimizing deflection in tight-tolerance applications.

Key Features

• Micrograin solid carbide construction for high hardness and edge retention
• ZrN coating reduces friction and extends tool life in dry and semi-dry cutting conditions
• 0.020 inch corner radius protects workpiece edges and reduces stress risers
• 45-degree helix angle improves chip evacuation and surface finish quality
• Centercutting design allows direct plunge milling without pre-drilled entry points
• Single-end, 2-flute configuration suited for slotting and pocket milling in harder materials

Compatibility

Designed as an OEM-style replacement and standard tooling option for 3/8 inch collets and tool holders used in vertical machining centers and manual milling machines accepting right-hand cutting end mills.

Installation Notes

This tool is installed by machinists and CNC operators using a 3/8 inch collet, end mill holder, or shrink-fit toolholder. Ensure the machine spindle is fully stopped and locked before loading or unloading the tool. Verify collet runout is within acceptable tolerance before beginning a cut, as excessive runout accelerates wear on carbide tooling. Follow shop-specific feeds, speeds, and depth-of-cut parameters appropriate to the workpiece material.
