Accupro 12181407 Corner Radius End Mill 3/8 in 2 Flute Carbide

Product Description

The ACCUPRO 12181407 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide, it delivers a 3/8 inch cutting diameter with a 0.015 inch corner radius that reduces stress concentrations at part corners and extends tool life in demanding cuts. The 2-flute, right-hand spiral configuration supports efficient chip evacuation in a wide range of materials. With an overall length of 2.5 inches and a 7/8 inch length of cut, this single-end mill is well-suited for CNC machining centers and manual mills where tight tolerances and consistent corner geometry are required. It is installed and used by machinists and tool and die professionals.

This end mill is appropriate for slotting, profiling, and peripheral milling applications where a small, controlled corner radius is needed to meet part print requirements. The bright uncoated finish makes it a practical choice for non-ferrous metals, aluminum alloys, plastics, and certain ferrous materials where coating is unnecessary or undesirable. The centercutting design allows plunge entry, adding versatility to its range of operations on CNC mills and manual machining setups.

Key Features

• 3/8 inch cutting diameter with a 0.015 inch corner radius for precise corner geometry
• Micrograin solid carbide construction for hardness and wear resistance
• 2-flute right-hand spiral design promotes efficient chip evacuation
• Centercutting capability allows direct plunge entry
• Bright uncoated finish suitable for non-ferrous and select ferrous materials
• Single-end configuration with 7/8 inch length of cut and 2.5 inch overall length

Compatibility

Designed as an OEM-style replacement or direct-use corner radius end mill for standard 3/8 inch collet or end mill holder systems on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Always power down and lock out the machine spindle before changing tooling. Secure the 3/8 inch shank firmly in a compatible collet or end mill holder, ensuring the tool is seated to the correct gage length. Inspect the cutting edges for chips or damage before use, and verify runout with a dial indicator after installation on critical-tolerance work.
