Great valueGood product

I need to use a mortiser for productivity in my shop--but I do not need to use it often. So these bits are a good choice. They seem to be well made and decent metal but at a great price. These are not the chisels for heavy use--but if like me you only need occasional use out of them, they are great.

Does okay. Just sharpen the blades

Works better than expected in my drill press, not mortise machine. Uses soft touch.

I am apparently going to have to buy a set that costs 3 times as much money to get the quality that I want.

I bought a set because I wanted to use them to hollow out a 2" x 2" x 4" piece of hardwood to make a business card holder. I found that they didn't cut as square on the sidewalls as I thought they would; however, I only bought a mortising kit to attach to my drill press and that kit was a problem in itself for mounting and accuracy.The other problem with mortise bits, is that they leave a small drill hole in the bottom of the wood. It wouldn't be a problem if I was using it simply as a tool to mortise a piece for a joint; however, I'm using it as an exposed/finished piece of wood. The way I solved that problem was to order a set of steel, end mills and used them on my drill press, creating a simple milling machine with the use of a two-axis vice mounted to the bed of the drill press. It easily squares the sides of the wood and also removes the the drill holes left in the bottom of the wood.

These were so poorly made and so inaccurately fitted I returned them immediately.Save your pennies and buy a better set.

Haven't used them yet, but they appear to be the same quality as the bit that came with it.

I bought the set to give me some variety of mortice sizes. The outside square grind is rough to say it kindly but the internal grind on the square chisel points are virtually unusable out of the box. Very disappointing.
