Promax 111-01622 Square End Mill 1/4 in 4 Flute Carbide Ticn

Product Description

The PROMAX 111-01622 is a solid carbide square end mill designed for precision material removal in ferrous and non-ferrous machining applications. Built from micrograin carbide stock and finished with a TiCN (Titanium Carbonitride) coating, it delivers extended tool life in high-speed cutting environments. The 4-flute, right-hand spiral geometry runs at a 40-degree helix angle for efficient chip evacuation. Cutting diameter is 0.25 inches with a 0.375-inch length of cut, a 0.25-inch shank diameter, and a 2-inch overall length. This is a single-end, non-centercutting tool suited for side milling, profiling, and slotting operations.

This end mill is intended for use on CNC machining centers and manual milling machines in shop environments handling precision part work. The regular-length profile and square shank make it a standard fit in collet chucks and end mill holders. Its TiCN finish is well-suited for cutting tool steels, stainless steels, and hardened materials where heat resistance at the cutting edge matters. Machinists and tool-and-die professionals working in job shops, production facilities, and maintenance machining will find this a reliable general-purpose choice in the PROMAX Series 111 lineup.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN coating provides heat and abrasion resistance at the cutting edge
• 40-degree right-hand spiral flute for efficient chip evacuation
• 4-flute geometry improves surface finish on profiling and side milling passes
• Square shank with tight diameter tolerance (-0.0001 / -0.0004 inches) for secure tool holding
• Non-centercutting design - suited for peripheral and side cutting, not plunge entry

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for standard 1/4-inch collet chucks, end mill holders, and milling machine spindles accepting a 0.25-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank to the recommended insertion depth for the holder type in use and torque the collet nut or set screw per the tool holder manufacturer specification. Verify runout with a dial indicator after seating before commencing the cut.
