This bit is great! Made a sign out of 1.5 inch plywood 24x96 cut like a beast! Cut through a screw and it didn’t hurt it at all. This thing is a beast! Looking forward using this to make cabinets on the Cnc! I will buy this again.

Used it for cutting mortis joints, it worked as planned.

Cut maple end grain counter top like butter. Very little tear out, very sharp - only used it a few times but appears to stay very sharp with repeated use - time will tell. Based on price - I couldnt ask for more!

The overall quality is excellent and it cuts Baltic birch plywood very well.

Super sharp and very accurate. Ive been using it to cut deep mortises in 4x4s. Flawless cuts.

I used this bit in a plunge router to carve deep mortices for concealed door hinges. It worked very well - nice and sharp with no burning. It was easy to plunge, and the finish on both the top and bottom surfaces was pretty good. Its also a really good size - the mortice in the photo is 21mm deep and I had plenty of plunge left and that was with an 18mm spacer!
