Value Collection 934-000-009 Square End Mill 5/32 in Cobalt

Product Description

The VALUE COLLECTION 934-000-009 is a cobalt square end mill designed for precision milling operations in metalworking and machining applications. Built from M42 cobalt high-speed steel, this double-end mill delivers good heat and wear resistance when cutting ferrous and non-ferrous materials. It measures 0.1563 inches in diameter with a 0.4375-inch length of cut, a 0.1875-inch straight shank, and a 2.25-inch overall length. The 40-degree spiral flute geometry promotes efficient chip evacuation, and the bright uncoated finish suits general-purpose milling without added coating cost. Licensed machinists and tool-and-die technicians are the typical end users for this type of cutter.

This end mill is suited for light-to-medium milling tasks on CNC machining centers, knee mills, and manual milling machines. Its compact 5/32-inch diameter makes it appropriate for slot milling, profiling, and pocket milling in confined areas or on small workpieces. The double-end configuration provides two usable cutting ends, extending tool life between replacements. Its right-hand cut and right-hand flute orientation match standard spindle configurations found in most production and job-shop environments.

Key Features

• M42 cobalt construction for improved heat resistance over standard HSS
• Double-end design provides two cutting ends per tool
• 40-degree helix angle promotes efficient chip flow and smooth cutting action
• Center-cutting capability allows direct plunge entry into workpiece material
• Bright uncoated finish suitable for general-purpose ferrous and non-ferrous milling
• Straight shank at 0.1875 inches compatible with standard collet and end mill holders

Compatibility

Designed as a general-purpose replacement or stock end mill for use in standard collet chucks and end mill holders accepting a 3/16-inch straight shank, within the Series 540 product line.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practice. Ensure the spindle is fully stopped and machine power is off before changing or seating the end mill in its holder. Verify collet or holder runout is within acceptable tolerance before beginning a cut, as excessive runout will accelerate edge wear on small-diameter tools. Follow machine manufacturer guidelines and applicable shop safety procedures when setting cutting parameters.
