"I bought these as I thought the four sizes would cover most of my needs. I already had a 3/8" one when I bought the morticer attachment for my pillar drill but I needed a smaller size for my latest project. So, I can only speak for the 6mm (1/4") chisel so far. It did the job very well and didn't clog up - even through a knot!"
"I`ve been very pleased with this product. So far I`ve used a couple of the mortice chisels and the results have been first class. The only reason I didn`t award 5 stars was that I haven`t had them long enough to report on their reliabilty though I feel there will be no problems there."
"Bought these after reading the reviews BUT the ones I ended up with are really bad, very roughly finished and all blunt, The arm on my morticer was bending trying to use them and that is 18mm dia solid steel plus once it had cut it was jammed into the wood (softwood) I ended up spending over an hour with a diamond stone to hone one smooth and to get it sharp"
