Promax 111-01224 Square End Mill 3/16 Inch 4 Flute Carbide

Product Description

The PROMAX 111-01224 is a solid carbide square end mill designed for high-performance milling in metalworking and machining applications. Built from micrograin carbide stock and finished with an AlTiN coating, it is engineered for cutting ferrous and hardened materials where heat and wear resistance are critical. The tool measures 3/16 inches in diameter with a 3/8 inch length of cut and a 2 inch overall length. Four spiral flutes at a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. Machinists and toolroom technicians select this end mill for finish milling, profiling, and slotting in CNC and manual milling setups.

This end mill is suited for small-diameter profiling, slotting, and contour milling in metals including steel alloys and stainless. The centercutting design allows plunge entry directly into the workpiece without pre-drilling. The right-hand cut and right-hand flute orientation match standard spindle rotation on vertical machining centers and manual knee mills. It belongs to the PROMAX Series 111 lineup and is appropriate for production machining environments where tight tolerances and consistent tool life are required.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN finish provides high-temperature resistance and extends tool life in dry or high-speed machining
• 40-degree helix angle with 4 spiral flutes for efficient chip evacuation and improved surface finish
• Centercutting geometry allows direct plunge milling without a starter hole
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation
• Square shank design for positive retention in standard end mill holders and collets

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 3/16 inch collets and end mill holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder and torque the retention nut to the holder manufacturer specification. Verify runout with a dial indicator before beginning production cuts to confirm proper seating and alignment.
