Accupro 12179537 Square End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12179537 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 0.5 inch cutting diameter, a 1.25 inch length of cut, and a 3 inch overall length, this tool is built for standard-reach slotting, profiling, and peripheral milling. The 0.5 inch shank diameter provides a rigid grip in collet or end mill holders. An AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials. Machinists and CNC operators in job shops and production facilities use this tool for high-speed dry cutting applications.

This end mill is suited for milling steel, stainless steel, cast iron, and other hard materials where heat buildup is a concern. The 4-flute, coarse-pitch design balances chip evacuation with surface finish quality. A 30-degree helix angle promotes smooth cutting action and reduces chatter. The centercutting geometry allows plunge entry directly into the workpiece. Right-hand cut and right-hand flute orientation make this compatible with standard CNC machining centers and manual knee mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat resistance and extended tool life in dry or high-speed cutting
• 4-flute, coarse-pitch design balances chip clearance and finish quality
• 30-degree helix angle reduces chatter and promotes smooth cutting
• Centercutting geometry enables direct plunge milling
• Right-hand cut, right-hand flute for use with standard spindle rotation

Compatibility

Designed as a standard 0.5 inch shank square end mill compatible with collet chucks, shrink-fit holders, and end mill holders sized for 0.5 inch shank tooling on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before mounting or removing the tool. Seat the shank to the minimum insertion depth recommended for the holder type to prevent pullout under load. Verify runout with a dial indicator after clamping, and confirm spindle rotation direction matches the right-hand cut orientation before starting the machine.
