Promax 119-04814 3/4 in 3-flute Roughing End Mill Altin

Product Description

The PROMAX 119-04814 is a solid carbide roughing finishing end mill engineered for aggressive material removal with a refined surface finish in a single operation. Designed for right-hand cutting with a 40-degree helix angle, this end mill features a 3/4-inch diameter, three flutes, and a 0.03-inch corner radius end geometry. The micrograin carbide substrate is coated with AlTiN for elevated heat resistance and extended tool life in ferrous and hardened materials. It is center-cutting and configured for straight-cylindrical shank mounting, making it compatible with standard collet and end mill holder setups.

This end mill is suited for milling operations in job shops, production machining environments, and toolrooms where both roughing and finishing passes are required. The corner radius geometry reduces chipping at the cutting edge and distributes cutting forces more evenly, making it appropriate for slotting, peripheral milling, and profiling on CNC machining centers and manual mills. The AlTiN coating supports dry or minimum-quantity lubrication machining on alloy steels, tool steels, and cast iron.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating provides high-temperature oxidation resistance for extended tool life
• 0.03-inch corner radius reduces edge chipping and stress concentration
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Center-cutting capable for plunge entry into workpiece
• Right-hand flute direction and right-hand cutting for standard spindle operation
• Single-end configuration, Series 119

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC and manual milling applications requiring a 3/4-inch straight-cylindrical shank and corner radius end geometry.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the collet or end mill holder to the recommended engagement depth and torque the retention hardware per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, and confirm spindle direction matches the right-hand cutting configuration of this tool.
