Sandvik Coromant 5721115 Face Mill Holder CAT40

Product Description

The SANDVIK COROMANT 5721115 is a CAT40 face mill holder designed for use on vertical and horizontal machining centers. It accepts face mills with a 1 inch pilot diameter and provides a 2 inch arbor length, giving the cutter proper clearance and rigid support during high-feed milling operations. The mounting hole thread size is 1 inch. Weighing 3.3 pounds, this holder is built for production environments where consistent tool runout and secure cutter retention are critical. It is installed and changed out by machinists and CNC setup technicians working with CAT40 spindle machines.

This face mill holder is suited for use in CNC machining centers equipped with CAT40 tooling interfaces. Typical applications include face milling, shoulder milling, and surface finishing operations on ferrous and non-ferrous workpieces. The 2 inch arbor length suits standard face mill cutter bodies where a moderate projection from the spindle nose is required. It is appropriate for both production shops and job shops running CAT40 equipped vertical or horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before mounting or removing the holder from the spindle. Use a calibrated torque wrench and the appropriate draw bar tool when securing the holder in the spindle; consult the machine tool manufacturer specifications for proper draw bar torque. Inspect the taper shank and spindle bore for chips or contamination before seating the holder.
