Value Collection 724-6418 Roughing End Mill 5/16 in Cobalt

Product Description

The VALUE COLLECTION 724-6418 is a single-end roughing end mill designed to remove large amounts of material quickly in milling operations. Built from M42 cobalt high-speed steel and finished with a TiN coating, it handles tough ferrous and non-ferrous materials with good wear resistance and heat tolerance. The mill measures 5/16 inch (0.3125 inches) in diameter with a 3/4 inch length of cut and a 2-1/2 inch overall length. Three flutes in a high-helix, right-hand configuration break chips aggressively and clear them from the cut zone, reducing heat buildup during aggressive stock removal passes. The 3/8 inch shank fits standard collets and end mill holders on most vertical machining centers and manual knee mills.

This roughing end mill is suited for machinist and toolroom applications in job shops, production floors, and maintenance environments. It is center-cutting, so it can be plunged directly into workpiece material where the operation requires it. The right-hand cutting direction is standard for conventional and climb milling on CNC and manual equipment. It is a practical choice for roughing passes on steel, alloy steel, and similar materials where cycle time and metal removal rate are priorities before a finish end mill is run.

Key Features

• M42 cobalt HSS construction for heat resistance and edge retention in tough materials
• TiN coating extends tool life and reduces friction during cutting
• 3 flutes with high-helix, right-hand spiral for aggressive chip evacuation
• Center-cutting design allows direct plunge entry into workpiece material
• 3/8 inch shank fits standard collets and tool holders
• Single-end configuration with right-hand cutting direction

Compatibility

Designed as a standard roughing end mill for use in vertical machining centers, CNC mills, and manual knee mills equipped with collet systems or end mill holders accepting a 3/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention hardware according to the machine tool manufacturer specifications. Inspect the cutting edges for chips or damage before each use, and verify runout with a dial indicator when precision is required.
