Value Collection 934-000-026 Cobalt Square End Mill

Product Description

The VALUE COLLECTION 934-000-026 is a cobalt square end mill designed for precision milling operations in metalworking and machining environments. Built from M42 cobalt high-speed steel, this double-end tool delivers a 5/64-inch (0.0781-inch) cutting diameter with a 1/8-inch (0.1250-inch) length of cut. The bright/uncoated finish suits applications where coating is not required or where regrinding is anticipated. With a 40-degree helix angle and two spiral flutes, the tool provides efficient chip evacuation and a clean cut on a range of ferrous and non-ferrous materials. Centercutting capability allows both plunge and peripheral milling. It is sized and configured for use in CNC machining centers, knee mills, and manual mills operated by skilled machinists and tool-and-die professionals.

This stub-length end mill is well suited for close-tolerance slotting, profiling, and light plunge operations in confined workspaces where a shorter reach is advantageous. The 3/16-inch straight shank fits standard collets and end mill holders common to both CNC and manual milling setups. The double-end design provides two usable cutting ends, extending tool life and reducing per-cut tooling cost. Right-hand cutting and right-hand flute direction conform to standard milling conventions. Applications include tool rooms, production shops, and maintenance machining operations where small-diameter cobalt tooling is required.

Key Features

• M42 cobalt construction for improved heat resistance and hardness retention compared to standard HSS
• Double-end design provides two cutting ends per tool
• 40-degree helix angle with two right-hand spiral flutes for efficient chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece
• Bright/uncoated finish compatible with regrinding services
• Stub length type for improved rigidity in tight-clearance setups
• Diameter tolerance of -0.0020 to +0.0000 inches for consistent fit in close-tolerance applications

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 3/16-inch straight-shank collets and end mill holders used in conventional and CNC milling machines.

Installation Notes

Installation of end mills should be performed by qualified machinists following shop safety procedures. Ensure the milling machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism to the collet manufacturer's specification. Verify runout with a dial indicator before beginning a cut, particularly critical at this small diameter.
