Accupro 14797329 Square End Mill 1/4 in 3 Flute Altin Carbide

Product Description

The ACCUPRO 14797329 is a solid carbide square end mill designed for precision milling in ferrous and hardened materials. It features a 1/4 inch diameter, a 3/8 inch length of cut, and a 30-degree helix angle that promotes chip evacuation and smooth cutting action. The AlTiN coating provides thermal resistance and extended tool life in high-temperature cutting environments. With a micrograin carbide substrate and right-hand flute and cutting direction, this tool delivers consistent performance in CNC machining centers and manual mills. It is a single-end tool with an overall length of 4 inches and is suited for machinists, tool and die makers, and shop technicians running precision metal removal operations.

This end mill is well-suited for milling slots, pockets, profiles, and contours in steel, stainless steel, cast iron, and similar ferrous materials. The extended reach design, with a 1.25 inch reach length and 2.0 inch neck length, allows access to deep features and recessed areas without compromising rigidity. The centercutting geometry permits plunge entry directly into the workpiece. It is typically used in job shops, production facilities, and maintenance operations where tight tolerances and surface finish quality are required.

Key Features

• AlTiN coating for high-temperature wear resistance and extended tool life
• Micrograin solid carbide substrate for rigidity and edge retention
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting geometry allows direct plunge milling
• Extended reach design with 1.25 inch reach length and 2.0 inch neck length for deep-feature access
• Right-hand cut and right-hand spiral flute configuration

Compatibility

Designed as a direct-fit replacement or new-installation end mill for standard 1/4 inch collets and tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated torque wrench and appropriate collet or end mill holder to secure the shank; the shank diameter tolerance is -0.0001 to -0.0003 inches. Verify runout with a dial indicator after installation to confirm proper seating before beginning a cut.
