Sandvik Coromant 6078825 Face Mill Holder CAT40

Product Description

The SANDVIK COROMANT 6078825 is a CAT40 face mill holder designed to secure face milling cutters on CNC machining centers and milling machines. It features a 3/4 inch pilot diameter and an arbor length of 1.5748 inches, providing a rigid, concentric interface between the spindle and the cutter body. The CAT40 taper shank is a widely used spindle connection standard in production machining environments. This holder is installed by machinists and tooling technicians in job shops and manufacturing facilities running face milling operations on ferrous and non-ferrous materials.

This face mill holder is suited for horizontal and vertical machining centers equipped with CAT40 spindle interfaces. It is intended for production and maintenance tooling setups where a reliable, repeatable cutter mount is required. The 3/4 inch mounting hole thread size accommodates compatible face mill cutter bodies. Typical applications include surface finishing and stock removal operations on workpieces requiring flat, square faces.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully powered down and locked out per OSHA lockout/tagout procedures. Ensure the CAT40 taper and spindle bore are clean and free of chips or debris before seating the holder. Use the appropriate drawbar torque procedure specified by the machine tool manufacturer. Verify cutter body seating and runout with a dial indicator before initiating a cut.
