They don't work well

For some reason (stupid?) I couldn't get a decent countersunk hole in any of these bits. Tried them on Douglas Fir, Pine, Baltic Birch Plywood, . none of these bits work well. Check out Amana 55229 finally bought this expensive attachment and it works great.

Pros
  • 5 pc 5 Flute 82 degree HSS Countersink Woodworking End Mill
Cons
  • Small things

Just a motley collection of scrap pieces

As per other reviews it appears to be a series of countersinking errors. Only 2 sizes marked. The sizes seem to be randomly packed. Yes there are 5 bits listed but two of them are 1/2", one is probably 12mm, the largest is 16mm and the smallest is "about" 3/8" as only two are marked. Cut? Mediocre. I will sharpen and hone on a grinder.

Pros
  • This countersink made of high-speed steel has a 5-point mount for silently countersinking brass, aluminium, plastic, wood and other materials. (Not for steel)
Cons
  • Unsure

really good for wood and metal!

top set! . With all the different diameters and pitch angles, they are ideal for sinking "just right". Set and I never knew how much I needed this set until I used them when I got them and many times since! :-) β—‹ This will make an amazing and essential addition to any drill collection at home or in the shop. special; β€’ They are made of sharp, hardened steel. β€’ They work great on wood and metal without rattling. just a very conscious but gentle cutting. β€’ Because they don't make aggressive deep…

Pros
  • Quickly and easily cut soft metal, wood, rubber, plastic and other materials.
Cons
  • money box price
