Accupro 12182241 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The ACCUPRO 12182241 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 1/4 inch cutting diameter, a 1-1/2 inch length of cut, and a 4 inch overall length, placing it in the extra-long category for extended reach work. The three-flute spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. The uncoated micrograin carbide construction provides rigidity and edge retention across a range of workpiece materials. This end mill is used by machinists in job shops, production environments, and tool rooms.

This end mill is suited for slotting, profiling, and peripheral milling operations where extra reach is required. The centercutting design allows plunge entry into the workpiece. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling machine setups. Its 1/4 inch shank diameter fits standard collets and end mill holders on vertical machining centers and manual knee mills alike.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the drawbar or clamping nut according to the machine manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
