Review on MK Morse AT18 Diameter Carbide by Roger Diaz

This product is great for splints and cast. I've used it occasionally in combination with another hole saw (E0206016 3-3/8" RemGrit Carbide Hole Saws, 86mm) which works well on plaster but not so well on battens. I've switched/alternated both. So far it has been used for about 20 holes with plaster and laths and no signs of dulling.
