Accupro 12181334 Corner Radius End Mill 1/4 in 2 Flute Carbide

Product Description

The ACCUPRO 12181334 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1/4 inch diameter cutting edge with a 0.045 inch corner radius, a 3/4 inch length of cut, and a 2-1/2 inch overall length. The 2-flute, right-hand spiral geometry supports efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides hardness and wear resistance suited for demanding cutting conditions. The bright/uncoated finish makes this tool appropriate for a range of general-purpose milling tasks. Licensed machinists and CNC operators are the primary users of this tool in job shop and production environments.

This end mill is used in vertical and horizontal milling machines as well as CNC machining centers for contouring, slotting, and profiling operations where a controlled corner radius is required. The centercutting design allows plunge entry directly into workpiece material. The 1/4 inch shank diameter fits standard collets and toolholders in that size range. A 40-degree helix angle promotes smooth cutting and helps reduce chatter during side milling passes. This tool is suited for use on ferrous and non-ferrous materials in both prototype and production runs.

Key Features

• 0.045 inch corner radius for consistent radiused edge profiles
• Micrograin solid carbide construction for hardness and edge retention
• 2-flute geometry with right-hand spiral for efficient chip removal
• Centercutting capability allows direct plunge entry
• 40-degree helix angle reduces chatter and improves surface finish
• Bright/uncoated finish suitable for general-purpose milling applications

Compatibility

Designed for use in standard 1/4 inch collets and toolholders on CNC machining centers, vertical mills, and similar milling equipment requiring a corner radius end mill in this size range.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the toolholder. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator after tool installation before beginning a cutting operation.
