Value Collection 723-5841 Roughing End Mill 1-1/4 in Cobalt

Product Description

The VALUE COLLECTION 723-5841 is a single-end roughing end mill designed for aggressive material removal in metalworking applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it features a 1.25-inch (1-1/4 inch) diameter with 6 flutes that break chips into smaller segments, reducing cutting forces and heat buildup compared to standard end mills. The 4-inch length of cut and 6.5-inch overall length accommodate deep-reach roughing passes. Right-hand cutting and right-hand flute direction are standard. This tool is used by machinists and tool-and-die professionals working on CNC mills, knee mills, and manual milling machines.

The 723-5841 is suited for roughing passes on ferrous metals, stainless steel, and other hard materials where an M42 cobalt substrate provides the necessary hot hardness and wear resistance. The non-center-cutting geometry means it requires a pre-drilled entry point or ramp entry rather than plunge cuts. It is commonly used in job shops, production facilities, and maintenance-and-repair machining environments where stock removal rate is the priority before a finish pass.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance over standard M2 tooling
• 6-flute roughing geometry breaks chips and reduces cutting forces on heavy cuts
• 1.25-inch diameter with matching 1.25-inch shank for rigid, straight-shank toolholding
• 4-inch length of cut allows deep-shoulder roughing passes
• Right-hand cut, right-hand helix — standard orientation for conventional CNC and manual mill spindles
• Bright, uncoated finish — suitable for use with cutting fluids on a wide range of ferrous materials

Compatibility

Designed as a straight-shank roughing end mill compatible with standard 1-1/4 inch collet chucks, shell mill adapters, and end mill holders used on vertical and horizontal milling machines.

Installation Notes

Installation is performed by qualified machinists. Ensure the machine spindle is fully stopped and the power is locked out before changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism to the toolholder manufacturer specification. Because this is a non-center-cutting end mill, do not plunge directly into solid material — use a pre-drilled hole or a ramping entry strategy.
