Accupro 12181320 Square End Mill 7/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12181320 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 7/32 inch (0.2188 inch) cutting diameter, a 2-flute spiral configuration with a 40-degree helix angle, and a right-hand cut with right-hand flutes. The centercutting geometry allows plunge entry as well as conventional side milling. Manufactured from micrograin solid carbide, this end mill delivers consistent edge integrity and dimensional accuracy in demanding shop environments. Licensed machinists and CNC programmers specify this tool for finish profiling, slotting, and light pocket work where tight tolerances are required.

This end mill fits standard 1/4 inch collet chucks and tool holders used on vertical machining centers, CNC mills, and manual knee mills. The regular-length configuration with a 5/8 inch length of cut and 2-1/2 inch overall length suits typical shallow-to-moderate depth slot and profile operations. The uncoated micrograin carbide substrate is well-suited for dry or flood-coolant applications in aluminum, brass, steel, and similar materials where a coated tool is not required.

Key Features

• Solid micrograin carbide construction for edge stability and wear resistance
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute orientation for standard CNC and manual mill setups
• Uncoated finish suited for applications where base carbide substrate performs best
• Tight mill diameter tolerance of +0.000 / -0.002 inches for predictable fit and finish

Compatibility

Designed as a direct-fit replacement or standard-stock square end mill for any machine tool equipped with a 1/4 inch collet, end mill holder, or shrink-fit toolholder accepting a 1/4 inch shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in an E-stop or locked-out state before seating or removing the end mill from the holder. Verify collet bore cleanliness and confirm the shank is inserted to the recommended engagement depth per the toolholder manufacturer guidelines. Inspect the cutting edges for chips or damage before each use.
