Value Collection 724-5194 End Mill 3/4 in 4 Flute Cobalt Tin

Product Description

The VALUE COLLECTION 724-5194 is a roughing-finishing end mill designed for aggressive material removal followed by a quality finish in a single tool. Machined from M42 cobalt high-speed steel with a Titanium Nitride (TiN) coating, it delivers extended tool life in ferrous and harder alloy applications. The 3/4-inch diameter, 4-flute, square-end geometry produces clean shoulder cuts and side milling passes. A 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces. This end mill is a single-end tool with a right-hand flute direction and right-hand cutting direction, suited for use in CNC machining centers and manual knee mills.

This end mill fits standard milling operations in job shops, production machining facilities, and toolrooms. With a 3-inch length of cut and 5-1/4-inch overall length, it handles deeper pockets and longer reaches without requiring extended-reach tooling. The 3/4-inch Weldon flat shank seats securely in side-lock holders, reducing pullout risk during heavy cuts. It is not center-cutting, so plunge milling requires pre-drilled lead holes or ramp entry. Typical users include machinists and CNC operators working in steel, stainless, and tough alloy materials.

Key Features

• M42 cobalt HSS construction for heat and wear resistance in hard materials
• TiN coating extends tool life and reduces friction at the cutting edge
• 4-flute square-end geometry for side milling and shoulder work
• 30-degree helix angle for smooth chip flow and reduced cutting forces
• Weldon flat shank for secure clamping in side-lock tool holders
• Not center-cutting — requires ramp entry or pre-drilled hole for plunge operations

Compatibility

Designed as a direct-fit replacement-style end mill for standard 3/4-inch side-lock or collet-style tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before installing or removing tooling. Seat the Weldon flat against the set screw in the holder and torque the retention hardware to the tool holder manufacturer's specification. Confirm runout with a dial indicator before beginning a production cut.
