The 5/16 inch hollow chisel mortising bit worked perfectly out of the box. Machining and finish appeared excellent to me and the chisel arrived sharp and ready to use. Very pleased with the purchase!

I did use these but if you don’t have a special machine you are kinda wasting your money. I thought I could push these through soft pine, NOPE. My bad but they aren’t very high quality. I have now seen the mortise machine and they are expensive.

There is a little bit of a learning curve based on the wood that you are using. I had never used these type of bits before, but I quickly realized that in order to effectively drill mortise/tenon joints without having to spend a ton of time chiselling, I could just measure and drill small pilot holes spaced just inside the span of each bit. Huuuge time saver! They are sharp and ready to work. Well oiled for storage (for the couple of sizes I haven't used and likely won't often). Amazing value for the set compared to others selling singles!!

Looks like a very strong reliable set of chiesles. I like that each bit has a container.

Well-made but it needs some kind of adaptor in order for this product to work on the drill press.

Auger does not draw the square bit into wood. Square bit spins in wood even when seated with pressure in soft wood. Shaft to drill is too long to perform detailed tasks on small pieces. Too much play on drill shank inside square bit hole. Bits are not very sharp.
