Accupro 12181531 Corner Radius End Mill 3/4 in 2 Flute

Product Description

The ACCUPRO 12181531 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 3/4-inch diameter with a 0.010-inch corner radius and a 1-1/2-inch length of cut, making it well suited for finishing passes that require a controlled edge break or slight radius on part features. The micrograin carbide construction provides wear resistance and edge retention at elevated cutting speeds. With 2 flutes and a right-hand spiral flute direction, this single-end centercutting tool handles both slotting and peripheral milling. Machinists and CNC operators rely on this geometry for light to medium material removal with consistent dimensional accuracy.

This end mill fits standard CNC machining centers, vertical mills, and manual knee mills equipped with an ER or straight-shank collet system accepting a 3/4-inch shank. It is appropriate for use in ferrous and non-ferrous materials where a corner radius profile is required to reduce stress concentration on workpiece edges. The bright, uncoated finish makes it a practical choice for applications where coating compatibility is a concern or where regrinding is planned. Overall length of 4 inches provides adequate reach for most general-purpose setups without excessive tool overhang.

Key Features

• 0.010-inch corner radius for controlled edge break on finished surfaces
• Micrograin solid carbide construction for extended tool life and edge retention
• Centercutting design allows plunge entry directly into the workpiece
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Right-hand cut, right-hand spiral geometry compatible with standard CNC spindle rotation
• Bright, uncoated finish suitable for regrinding or coating-sensitive applications

Compatibility

Designed for use in CNC machining centers and manual mills with collet or chuck toolholding systems that accept a 3/4-inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or toolholder to the minimum recommended insertion depth and torque the retention nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
