Value Collection 723-5797 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The VALUE COLLECTION 723-5797 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, it delivers the heat resistance and edge retention needed for interrupted cuts and hard materials. The cutter measures 1 inch in diameter with a 4-inch length of cut and a 3/4-inch shank diameter. With 5 flutes and a right-hand cutting direction, it is suited for roughing passes where stock removal rate takes priority over surface finish. Licensed machinists and tool-and-die professionals typically reach for this style of end mill when working with alloy steels, stainless, or other tough workpiece materials.

This roughing end mill fits vertical and horizontal milling machines, CNC machining centers, and manual knee mills that accept a 3/4-inch shank. It is appropriate for roughing applications in job shops, production machining environments, and maintenance-repair operations. The single-end configuration and non-centercutting geometry mean it is intended for peripheral milling and slotting entries made through the side of the material rather than plunge cutting.

Key Features

• M42 cobalt HSS construction provides elevated heat and wear resistance compared to standard M2 HSS
• 5-flute roughing geometry increases metal removal rates while reducing chatter and cutting forces
• 1-inch cutter diameter with a 4-inch length of cut handles deep-reach roughing passes
• 3/4-inch shank diameter fits standard collets and end-mill holders on most milling spindles
• Right-hand cutting and right-hand flute direction for conventional milling machine setups
• Bright, uncoated finish allows visual inspection of edge condition without coating interference

Compatibility

Designed for use in milling machines and machining centers that accept a 3/4-inch straight shank end mill holder or collet. Suitable for roughing operations on ferrous and difficult-to-machine alloy materials.

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and lock out the spindle before loading or removing the tool. Seat the shank fully in the holder and torque set screws according to the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a cut. Non-centercutting geometry requires a side-entry or ramping approach rather than a direct axial plunge.
