Accupro 12181395 Square End Mill 11/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12181395 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 2-flute, spiral configuration with a 40-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The centercutting geometry allows plunge milling as well as conventional peripheral cuts. With a mill diameter of 0.3438 inches (11/32 inch) and a 3/8-inch shank, this end mill fits standard collet and chuck setups common on vertical mills, machining centers, and CNC routers. Machined from micrograin carbide, it holds tight tolerances and resists wear during extended runs.

This end mill is suited for general-purpose profiling, slotting, and light pocket milling in job shop and production environments. The uncoated finish makes it a straightforward choice for aluminum, brass, and other non-ferrous alloys, as well as plastics and composites where coating buildup is a concern. The regular-length design and right-hand cut with right-hand flute geometry make it a standard workhorse tool for machinists and tool-and-die professionals handling everyday material removal tasks.

Key Features

• Solid micrograin carbide construction for improved wear resistance and edge retention
• 40-degree helix angle promotes chip evacuation and reduces heat buildup
• Centercutting design allows direct plunge entry without a pre-drilled hole
• 2-flute configuration ideal for non-ferrous metals, plastics, and composites
• Right-hand cut and right-hand flute, standard for most vertical milling setups
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as an OEM-style replacement and standard cutting tool for use in vertical machining centers, CNC mills, and manual knee mills accepting a 3/8-inch shank collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Seat the shank fully into the collet or holder to the minimum recommended engagement depth to prevent pullout under load. Verify runout with a dial indicator before beginning a cut, and confirm feeds, speeds, and depth-of-cut settings are appropriate for the workpiece material.
