Value Collection 723-4403 Roughing End Mill 3/16 in Cobalt

Product Description

The VALUE COLLECTION 723-4403 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, this tool delivers solid performance in ferrous and harder workpiece materials. The 3-flute geometry provides an efficient balance of chip evacuation and cutting edge strength. With a 3/16-inch cutting diameter, a 1/2-inch length of cut, and a 3/8-inch shank diameter, it is sized for lighter roughing passes on CNC machining centers and manual mills. The right-hand cutting direction and high-helix flute design promote clean chip flow during extended cuts.

This roughing end mill is suited for job shops, toolrooms, and production machining environments where rapid stock removal is the priority before a finishing pass. The centercutting design allows plunge entry, adding flexibility in pocket-milling and ramp-entry operations. The M42 cobalt grade provides improved heat and wear resistance compared to standard M2 HSS tooling, making it a practical choice for stainless steel, alloy steel, and other difficult-to-machine materials at moderate cutting speeds.

Key Features

• M42 cobalt construction for improved heat resistance over standard HSS grades
• 3-flute single-end geometry balances chip clearance and edge strength
• Centercutting capable — supports plunge entry and ramp milling
• High-helix flute direction promotes efficient chip evacuation
• Bright uncoated finish suitable for use with cutting fluids on a wide range of materials
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as a standard single-end roughing end mill with a 3/8-inch straight shank, compatible with any milling machine, CNC machining center, or manual mill equipped with an appropriately sized collet, end mill holder, or ER chuck system.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the power source is locked out before changing tooling. Seat the shank securely in the collet or holder to the recommended minimum engagement depth to prevent pullout during cutting. Follow the tool manufacturer and machine builder guidelines for speed and feed selection based on workpiece material and depth of cut.
