Promax 101-01222 Roughing End Mill 3/16 in 3 Flute Carbide

Product Description

The PROMAX 101-01222 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from micrograin solid carbide and finished with a TiCN coating, this tool delivers strong wear resistance and extended tool life in demanding cutting conditions. The 3-flute fine-pitch geometry produces a controlled chip load, reducing chatter and heat buildup during roughing passes. With a 40-degree maximum helix angle and right-hand cutting and flute direction, it is suited for high-speed roughing on ferrous and non-ferrous workpieces. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual knee mills.

This end mill is sized at 3/16 inch diameter with a 3/8 inch length of cut and a 2-inch overall length. Its centercutting capability allows plunge entry into the workpiece without a pre-drilled hole. The compact diameter makes it appropriate for slot milling, pocketing, and profile roughing in close-tolerance or smaller-scale workpieces. It is well suited to production shops, tool rooms, and job shops requiring consistent performance in roughing operations where cycle time and surface integrity during the first pass are both priorities.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating reduces friction and extends cutting life
• 3-flute fine-pitch design for controlled chip evacuation during roughing
• 40-degree maximum helix angle for smooth, high-efficiency cuts
• Centercutting geometry allows direct plunge milling
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 3/16 inch collet or end mill holder systems used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before installing or removing the end mill from its holder. Use a properly sized collet or end mill holder that matches the 3/16 inch shank diameter to prevent runout. Verify clamping torque with the tool holder manufacturer's specifications before beginning a cut.
