Value Collection 934-000-087 Square End Mill 3/16 in Cobalt

Product Description

The VALUE COLLECTION 934-000-087 is a cobalt square end mill designed for milling operations in metal and alloy workpieces. Built from M42 cobalt high-speed steel, this double-end tool delivers extended tool life in harder materials compared to standard HSS. The mill features a 3/16 inch cutting diameter, a 9/32 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation. Four right-hand spiral flutes with a bright uncoated finish make this mill suitable for general-purpose slotting, profiling, and peripheral milling. It is centercutting, allowing direct plunge entry into the workpiece. Machinists, tool-and-die workers, and production shop technicians install and operate this tool.

This end mill is suited for use on manual knee mills, CNC machining centers, and benchtop milling machines running ferrous and non-ferrous metals. The stub length classification and straight shank make it compatible with standard ER collets and end mill holders. The double-end design provides a second usable cutting end, extending the effective service life of each tool. Typical applications include keyway cutting, shoulder milling, and light slotting in steel, stainless, and cast iron workpieces. Right-hand cut and right-hand flute geometry are standard for conventional and climb milling on most setups.

Key Features

• M42 cobalt construction for improved hardness and heat resistance over standard HSS
• Double-end design provides two usable cutting ends per tool
• 40-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge milling without pre-drilling
• Bright uncoated finish suitable for use with cutting fluids on a wide range of materials
• Straight shank fits standard ER collets and end mill holders

Compatibility

Designed as a general-purpose OEM-style replacement or production-use square end mill for standard straight-shank end mill holders and ER collet systems used on vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify collet or holder bore matches the 3/16 inch shank diameter and that the tool is seated to the correct projection length before tightening. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and cut depth.
