Accupro 12181620 Square End Mill 7/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12181620 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 7/32 inch (0.2188 inch) cutting diameter and a 40-degree helix angle, this tool delivers efficient chip evacuation and clean square-shoulder cuts. The micrograin carbide construction provides the rigidity and edge retention needed for demanding materials. Two right-hand spiral flutes and a centercutting geometry allow both plunge and side milling. Licensed machinists and CNC operators install this tool in standard end mill holders or collet chucks for finishing and semi-finishing passes.

This stub-length end mill suits applications where short tool overhang is preferred to maximize rigidity and minimize deflection. It is appropriate for slot milling, profiling, and face milling operations on ferrous and non-ferrous materials in both manual and CNC milling machines. The 1/4 inch shank diameter fits common collet sizes found in vertical machining centers and knee mills. The uncoated finish makes it well-suited for use with cutting fluid where coating compatibility may be a concern.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• 40-degree right-hand spiral helix for efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Stub length (3/8 inch LOC) maximizes rigidity and reduces deflection
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Uncoated finish compatible with a wide range of cutting fluid applications

Compatibility

Designed as an OEM-style replacement or direct fitment for standard 1/4 inch collet and end mill holder setups used in CNC vertical machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Power down and lock out the spindle before inserting or removing the end mill. Seat the shank fully into the collet or holder to the minimum insertion depth recommended by the toolholder manufacturer to prevent pullout. Inspect the cutting edges for chips or wear before each use and replace the tool if edge integrity is compromised.
