Value Collection 723-3307 Cobalt Square End Mill 1/2 in

Product Description

The VALUE COLLECTION 723-3307 is a cobalt square end mill designed for milling ferrous and hard materials in machining applications. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance needed for aggressive cuts. The 1/2 inch diameter cutter features 4 spiral flutes with a 30-degree helix angle, right-hand cutting and flute direction, and a bright/uncoated finish. The long-series geometry provides extended reach for deep-pocket work. This is a single-end tool with a 1/2 inch straight shank, suitable for use in standard end mill holders, collet chucks, and milling machine spindles.

This end mill is suited for general-purpose slot milling, profiling, contouring, and step milling on CNC machining centers and manual knee mills. The 2 inch length of cut and 4 inch overall length make it appropriate for deep-slot and cavity work where a standard-length tool would lack reach. It is centercutting, allowing plunge cuts into the workpiece. Machinists working with alloy steels, stainless, and other difficult-to-cut materials benefit from the cobalt substrate at higher cutting temperatures.

Key Features

• M42 cobalt high-speed steel construction for improved red hardness and wear resistance
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge milling
• Long-series length type with 2 inch length of cut and 4 inch overall length for deep-reach applications
• Bright/uncoated finish compatible with cutting fluids and oils without coating interaction
• Right-hand cut and right-hand flute direction for standard spindle use

Compatibility

Designed as a general-purpose replacement or stocking end mill for use in standard 1/2 inch end mill holders, ER collet chucks, and Weldon-style holders on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist with the machine spindle fully stopped and locked out per applicable safety procedures. Ensure the shank is fully seated to the recommended engagement depth in the holder before tightening. Inspect the tool for runout after mounting using a dial indicator before beginning a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
