Promax 100-01214 Roughing End Mill 3/16 in 3 Flute Solid Carbide

Product Description

The PROMAX 100-01214 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), this tool handles high-heat cutting environments where tool life and edge retention matter. It features a 3/16 inch cutting diameter, three flutes with a coarse pitch, and a 30-degree maximum helix angle. The centercutting geometry allows plunge entry as well as peripheral cutting. This tool is installed and used by machinists and CNC programmers running ferrous and hardened workpiece materials in production and job-shop settings.

This roughing end mill is suited for use in vertical machining centers, CNC knee mills, and manual milling machines where stock removal rate is the priority over surface finish. The coarse pitch flute geometry breaks chips aggressively, reducing heat buildup and tool deflection during roughing passes. With a 5/8 inch length of cut and 2 inch overall length, it fits standard toolholders with a 3/16 inch bore. Applications include roughing slots, pockets, and contours in steel, stainless, cast iron, and similar ferrous alloys.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention at elevated cutting temperatures
• AlTiN coating improves oxidation resistance and extends tool life in dry and high-speed cutting
• Coarse pitch, 3-flute design promotes aggressive chip evacuation during roughing passes
• Centercutting geometry permits direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute spiral for use on standard spindle rotation
• Shank diameter matches cutting diameter at 3/16 inch for direct collet or endmill holder mounting

Compatibility

Designed as a direct-mount roughing end mill for toolholders accepting a 3/16 inch shank diameter, including ER collet chucks, set-screw end mill holders, and shrink-fit holders sized for 3/16 inch bore.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or drawbar is de-energized before loading or removing the tool. Seat the shank fully into the holder to the recommended gauge-line depth and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to avoid premature tool failure or workpiece damage.
