Promax 100-01612 Roughing End Mill 1/4 in 4 Flute Carbide

Product Description

The PROMAX 100-01612 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from solid carbide and coated with TiCN, it handles tough ferrous and non-ferrous materials with consistent performance. The 1/4 inch diameter, 4-flute, coarse-pitch design breaks chips efficiently and reduces cutting pressure across the full 3/4 inch length of cut. Right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling setups. Machinists and tooling technicians install this style of end mill for roughing passes where speed and stock removal take priority over surface finish.

This end mill is suited for roughing operations on machining centers, CNC mills, and manual knee mills in job shop and production environments. The coarse pitch geometry is appropriate for cutting steel, stainless, aluminum, and similar materials where chip evacuation is critical. The 2.5 inch overall length and 1/4 inch shank keep tool overhang short, which reduces deflection and chatter during heavy cuts. Applications include profiling, slotting, and pocketing operations where rapid material removal is the priority before a finish pass.

Key Features

• Solid carbide construction for rigidity and heat resistance
• TiCN coating improves wear resistance and reduces friction at the cutting edge
• Coarse pitch, 4-flute geometry promotes chip breaking and efficient stock removal
• Center-cutting design allows plunge entry into the workpiece
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation
• 30-degree maximum helix angle balances chip flow and cutting stability

Compatibility

Designed as an OEM-style solid carbide roughing end mill for use in standard 1/4 inch collets and end mill holders on CNC and manual milling machines.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism to the machine or holder specification. Inspect the cutting edges for chips or damage before each use, and verify runout with a dial indicator when close-tolerance work is required.
