Value Collection 723-6701 Roughing End Mill 1/4 in Cobalt

Product Description

The VALUE COLLECTION 723-6701 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting ferrous metals and hardened materials. The 1/4 inch diameter cutter features 3 flutes with a right-hand cutting and right-hand flute direction, and carries a TiN (titanium nitride) coating to reduce friction and extend tool life. The shank diameter is 3/8 inch, the length of cut is 7/8 inch, and the overall length is 2-11/16 inches. This tool is installed and operated by machinists and tooling technicians on manual or CNC milling machines.

This roughing end mill is suited for slotting, profiling, and pocketing operations where fast stock removal is the priority over finish quality. The cobalt M42 construction handles interrupted cuts and harder workpiece materials better than standard HSS tooling. The TiN coating adds surface hardness and lubricity, making it a practical choice for production environments running ferrous alloys, stainless steel, and similar materials. At 0.02 pounds, it is a lightweight tool appropriate for small-diameter roughing passes on benchtop and full-size vertical mills alike.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance
• TiN coating reduces friction and extends cutting tool life
• 3 flutes with right-hand cut and right-hand helix for efficient chip evacuation
• 1/4 inch cutting diameter with 3/8 inch shank for standard collet compatibility
• Single-end design; not center-cutting — requires a pre-drilled or plunged entry point
• 7/8 inch length of cut suitable for shallow-to-moderate depth roughing passes

Compatibility

Designed for use in standard milling machine collets and tool holders accepting a 3/8 inch shank diameter, including ER and TG-style collet systems commonly found on vertical and CNC knee mills.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and locked out before loading or changing the tool in the collet or end mill holder. Seat the shank fully into the holder and torque the drawbar or collet nut to the machine manufacturer's specification. Because this end mill is not center-cutting, do not plunge directly into solid material — use a ramping, helical, or pre-drilled entry path.
