So far I am very happy with this. Works with my old machine very well. Only draw back is that it gets after a some used.

I bought this as a gift for my husband. He said it took a little practice but loves the set.

Cutting edges are very sharp. Looking forward to using them.

I am not a "heavy" user, but even if I was, I would think that these Mortise bits will last quite some time.

Excellent Mortising Bits. Each Bit is individually cased in a very sturdy enclosure of it's own. Clearly marked as to their size. These bits are worthy of a more impressive outer case, but I can't complain. Instead, I shall build them one. They are quite worthy of my effort. Would like to see this manufacturer make an assortment of larger bits.
