"Have used this with my new Titan drill to chop out some recesses for pipework etc and it has so far kept its edge with no noticeable deterioration in its performance. Hopefully this will continue if I don't abuse it!"
"Used to put chases in hard brick walls. Sharpness allows greater finesse than the chisel bit supplied with the low-cost SDS plus drill I use. Also, does not stick and heat up in the chuck like a competitor bit did - despite using oil. Grinding of edge is slightly skewed but this does not affect performance."
