Value Collection 6-901-515 Square-shoulder End Mill R8

Product Description

The VALUE COLLECTION 6-901-515 is an indexable square-shoulder end mill designed for precision milling operations in metalworking environments. With a 1-1/4 inch cutting diameter and a maximum depth of cut of 0.656 inches, this toolholder is built for controlled shoulder and face milling passes. The R8 shank provides positive engagement in compatible vertical milling machines. It accepts TPC 32, TPG 32, and TPU 32 style inserts, secured by screw clamping for reliable insert retention under load. The 2-flute, 2-insert configuration supports chip clearance during aggressive cuts. Overall length is 5-37/64 inches, and the tool weighs 1.19 pounds.

This end mill is intended for use in machine shop environments, tool rooms, and production milling applications. The R8 shank is a standard taper found on Bridgeport-style knee mills and similar vertical milling machines. It is suited for squaring shoulders, facing stock, and step milling in ferrous and non-ferrous materials when used with appropriate insert grades. Machinists, toolmakers, and CNC setup technicians are the primary users. Coolant-through capability is not included in this configuration.

Installation Notes

Installation requires powering down and locking out the milling machine spindle before mounting or removing the toolholder. The R8 shank must be clean and free of nicks before seating in the spindle bore; tighten the drawbar to the machine manufacturer's specification. Insert seating surfaces should be cleaned before each insert change to ensure proper clamping and runout. Follow applicable shop safety procedures and machine guarding requirements during setup and operation.
