Promax 101-03212 Roughing End Mill 1/2 in 4 Flute Carbide

Product Description

The PROMAX 101-03212 is a single-end roughing end mill designed for aggressive material removal in CNC machining and manual milling operations. Built from solid carbide with a TiCN coating, this tool handles tough ferrous and non-ferrous materials with a high-helix, fine-pitch flute geometry that reduces chatter and improves chip evacuation. The 1/2-inch diameter body carries four right-hand flutes with a maximum helix angle of 40 degrees, and the center-cutting design allows plunge entry without a pre-drilled pilot hole. Machinists and tool-and-die professionals use this end mill where high metal removal rates and surface finish control are both required.

This end mill is suited for roughing passes on milling machines and machining centers in job shops, production facilities, and toolroom environments. With a 1/2-inch shank diameter and a 1-1/4-inch length of cut, it fits standard ER and end mill holders without modification. The 3-inch overall length keeps the tool rigid in short-to-medium reach applications. Right-hand cutting direction pairs with standard CNC spindle rotation, making setup straightforward for conventional and climb milling strategies.

Key Features

• Solid carbide construction for high rigidity and heat resistance at elevated feed rates
• TiCN coating reduces friction and extends tool life on ferrous materials
• 40-degree high-helix angle promotes efficient chip evacuation and reduces cutting forces
• Center-cutting capability allows direct plunge entry
• Fine-pitch roughing geometry minimizes vibration during heavy stock removal
• Right-hand cut and right-hand flute direction for standard spindle compatibility

Compatibility

Designed as an OEM-style roughing end mill for use in standard 1/2-inch end mill holders, ER collet chucks, and Weldon-shank tool holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout specifications. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify shank seating depth and check runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
