Promax US362048 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The PROMAX US362048 is a single-end, square-profile solid carbide end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 1/4 inch mill diameter, a 1 inch length of cut, and a 46/48 degree variable helix angle that reduces chatter and improves chip evacuation at higher feed rates. The ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in abrasive materials. Micrograin carbide construction provides rigidity and edge retention. This tool is intended for use by machinists and CNC operators working in job shops, production environments, and tool rooms.

The US362048 is suited for slotting, profiling, and peripheral milling applications in materials such as aluminum, brass, steel, and hardened alloys. With a right-hand cut and right-hand spiral flute direction, it is compatible with standard CNC machining centers and manual mills running conventional or climb milling operations. The straight-cylindrical shank fits standard collets and end mill holders sized for 1/4 inch tooling. Its 3-inch overall length and standard length classification make it a practical choice for general-purpose work where extended reach is not required.

Key Features

• 46/48 degree variable helix angle reduces harmonic vibration and chatter during cuts
• Variable index flute spacing further dampens resonance for improved surface finish
• ZrN coating improves wear resistance and reduces heat buildup at the cutting edge
• Micrograin solid carbide blank provides consistent edge geometry and rigidity
• Centercutting design allows plunge entry into workpiece material
• Right-hand cut and right-hand spiral compatible with standard CNC setups

Compatibility

Designed for use with standard 1/4 inch collets and end mill holders on CNC machining centers and manual milling machines. Part of the PROMAX Series US362 variable helix end mill line.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the collet or holder to the recommended gauge length and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing a new operation to avoid premature tool wear or edge damage.
