Copper, brass, plastics
Hardox, Hastelloy, Inconell, Nimonic and other special alloys

Features:
Excellent drainage, not to be unscrewed, the resulting surface without scratches, great centering tools-holes
The grooves of the countersink are ground with a CBN wheel, thanks to The emu is easier and smoother to run compared to conventional countersinks where the grooves are milled.
To run is always the highest point of the diameter, ie when sinking, the material does not rub against the wall of the countersink, thus reducing the necessary Cutting force and the heat generated is also reduced -> which increases the life of the countersink.
