Promax 190-06414 Solid Carbide Square End Mill 1 Inch

Product Description

The PROMAX 190-06414 is a solid carbide square end mill designed for both roughing and finishing operations in a single tool. Built with four flutes and a 40-degree helix angle, it features an AlTiN coating and chipbreaker geometry that improve chip evacuation and heat resistance in demanding cuts. The 1-inch cutting diameter and 1.75-inch length of cut make it well-suited for full-depth profiling and slotting passes. At 4 inches overall length with a 1-inch shank diameter, this is a regular-length tool in the PROMAX Series 190 lineup. Machinists and tool crib supervisors working in job shops, aerospace component production, or general metalworking will recognize this as a production-grade end mill.

This end mill is used in CNC machining centers and manual knee mills for ferrous and hard-metal applications. The AlTiN finish improves performance in dry or near-dry cutting conditions at elevated surface speeds. The chipbreaker geometry reduces cutting forces during heavy stock removal, while the square end profile allows for sharp shoulder milling and precise floor finishing. Right-hand cut and right-hand flute direction are standard for conventional spindle-up machining setups.

Key Features

• 4-flute, 40-degree helix geometry for balanced chip load and improved surface finish
• AlTiN coating for high-heat resistance and extended tool life in ferrous materials
• Chipbreaker design reduces cutting forces during roughing passes
• Square end profile enables shoulder milling and flat-floor finishing in a single tool
• Solid carbide construction provides rigidity and wear resistance over high-speed tool paths
• Single-end, right-hand cut configuration for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-specification end mill for CNC machining centers and manual mills using 1-inch straight-shank toolholders, collet chucks, or hydraulic holders with appropriate 1-inch bore.

Installation Notes

Installation should be performed by a qualified machinist following shop safety and toolholding procedures. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Insert the shank to the recommended grip depth in the toolholder - do not allow the flute to contact the holder bore. Verify runout after seating and before initiating any cutting cycle.
