Value Collection 219-3015 End Mill Holder 3MT 3/8 in

Product Description

The VALUE COLLECTION 219-3015 is a taper shank end mill holder designed for use in milling machines and machining centers that accept a 3MT (Morse Taper No. 3) spindle interface. The holder features a 3/8-inch tool bore and a projection of 1.969 inches, positioning the cutting tool at a fixed, repeatable standout from the spindle face. It accepts standard end mills and other shank tooling in the 3/8-inch diameter range. At 0.96 pounds, it is a solid, low-profile holder suited for general-purpose milling work. No through-coolant port is included in this design.

This end mill holder is intended for use in manual knee mills, CNC bed mills, and similar machine tools equipped with a No. 3 Morse Taper spindle socket. It is typically used in job shop, maintenance machining, and production environments where a secure, concentric tool grip is required for face milling, slotting, and peripheral milling operations. The 1.969-inch projection provides adequate clearance for most standard end mill applications without excessive overhang.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and de-energize the machine spindle completely before changing tooling. Clean the taper bore and spindle socket with a lint-free cloth to remove chips and oil contamination before seating the holder, as contamination affects runout. Use a drawbar or drift as appropriate to the machine design when securing or removing the holder.
