Value Collection 934-000-083 Square End Mill 1/8 in Cobalt

Product Description

The VALUE COLLECTION 934-000-083 is a cobalt square end mill built for precision milling in a wide range of metalworking applications. This double-end, four-flute tool measures 1/8 inch in diameter with a 3/16 inch length of cut and a 2 inch overall length. The 3/16 inch straight shank fits standard collet and chuck setups. Manufactured from M42 cobalt high-speed steel, it handles harder workpiece materials better than standard HSS. The 40-degree helix angle improves chip evacuation and surface finish. The bright, uncoated finish is suitable for general-purpose cuts where coating is not required.

This end mill is suited for light slotting, profiling, and contouring operations on ferrous and non-ferrous metals. The stub-length geometry provides rigidity in tight setups and low-clearance fixtures. Its centercutting design allows plunge entry directly into the workpiece. The double-end configuration extends tool life by offering a second usable end when one side wears. Machinists and tool-and-die professionals working on CNC mills, manual knee mills, and similar machines will find this tool appropriate for fine detail work at small diameters.

Key Features

• M42 cobalt construction for improved hardness and heat resistance over standard HSS
• Double-end design provides two cutting ends per tool
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting geometry allows direct plunge milling
• Right-hand cut with right-hand spiral flutes for standard spindle operation
• Stub length improves rigidity in compact or low-clearance setups

Compatibility

Designed for use in standard collet chucks and end mill holders accepting a 3/16 inch straight shank. Fits CNC machining centers and manual milling machines configured for small-diameter tooling in the Series 549 stub-length class.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully powered down and locked out before loading or removing the tool. Seat the shank fully in the collet or holder and torque to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, as small-diameter end mills are sensitive to even minor misalignment.
