Value Collection 723-5835 Roughing End Mill 1-1/4 in 6 Flute

Product Description

The VALUE COLLECTION 723-5835 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 handles tough ferrous and non-ferrous workpiece materials where standard HSS tooling falls short. The 1.25-inch diameter cutter features 6 flutes configured for a right-hand cutting direction and right-hand flute spiral. With a 2-inch length of cut and 4.5-inch overall length, it is suited for medium-depth roughing passes in vertical mills and CNC machining centers. Licensed machinists, tool-and-die makers, and production machinists are the primary users.

This roughing end mill is used in job shop and production environments for roughing slots, pockets, and profile cuts where chip clearance and tool rigidity are priorities. The 6-flute geometry distributes cutting load across more edges than standard 4-flute designs, reducing chatter on rigid setups. The 1-1/4 inch shank diameter matches the cutter diameter, providing maximum rigidity in compatible end mill holders and collet chucks. It is not center-cutting, so it requires a pre-drilled or pre-milled entry point before plunging.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard M2 HSS
• 6-flute design distributes cutting forces for reduced vibration on stable setups
• 1.25-inch diameter with matching 1.25-inch shank for maximum tool rigidity
• 2-inch length of cut suitable for medium-depth roughing passes
• Right-hand cut, right-hand helix configuration standard for most vertical milling applications
• Bright, uncoated finish — compatible with regrinding and recoating services

Compatibility

Designed as a standard-geometry replacement roughing end mill for use in 1-1/4 inch end mill holders, shell mill adapters with appropriate collets, or direct-mount tool holders accepting a 1.2500-inch shank diameter.

Installation Notes

Installation is performed by machinists using an appropriate end mill holder or collet chuck rated for the 1.25-inch shank. Ensure the machine spindle is fully stopped and locked before loading or changing tooling. Verify holder runout with a dial indicator before cutting to avoid premature edge wear. Because this tool is not center-cutting, a pilot hole or side-entry approach is required at the start of any pocket operation.
