Great tool!
I bought these to make some mortice & tenon joints (the mortice part anyways).They appear to be good quality and at under £19 for 4 they are not a bad price either. The shank is 19mm which typically indicates these are for use in a drill press, you might be able to fit them in a hand drill, but hand drills are not really designed to assert the force needed for the outer square chisel part to cut out what the drill does not.Normally I would have used a Forstner bit to cut out most of the mortice and then cleaned up the edges with a chisel, using these square hole drill bits makes morticing so much quicker and easier!If you overlap the cutting area by about .5mm each time you have hardly no cleanup to do at the end, I found it best to work from both ends of the mortice at the same time alternating between the two so you end up with one final hole to drill in the middle. This gives you better support than trying to cut at the end of a hole and only having half the drill bit in contact with some wood.Also, if you can drill the hole a little bit deeper than the tenon requires, you don't even have to tidy up the bottom of the mortice!

SDS drill bits
Drilled into concrete fence posts without problem using an SDS drill. I would say these drill bits are as good as some brand names that I’ve used before and didn’t last!

Great for what they do takes a lot of work out of doing locks on door and saves you money on calling a carpenter to do same.

Molto utili
Ottime e di buona qualità anche se un poco più grandi di quanto mi aspettassi. Serve però la guida, a mano libera non è facile utilizzarle
