Two improvements inside, same shape outside
The new generation Monarch Handpiece (#004-921) now has more power added to the legendary ultra-fine control loved by top engravers and stone setters, but the shape remains the same user-friendly, ergonomic design preferred by Monarch users.
The added power comes from this new design: a heavier piston made with an advanced low-friction sleeve. This not only gives greater impact power for stone setting and engraving, it provides longer handpiece life by eliminating piston wear.
The second improvement is a new tool receiver cartridge that is mechanically stronger and provides better control of tool movement for smoother cuts and longer graver life.
Both of these improvements can be added to any existing Monarch by replacing the original piston and receiver with these new designs.
