Review on CSK SET 5 82 Degree Countersink - Champion 5 Piece Kit by Josh Maher

works well with aluminium. When I try to use it on titanium and other carbides it has trouble causing most countersinks edge breaks and also creates burrs on harder metal parts which defeats the purpose I bought this non-groove set for , so as not to create burrs. when rubbing. If you stick to softer metals then you'll be fine if you're looking for a burr-free finish. Otherwise, you will need to shuffle the roll with your holes afterwards. This might be a decent set for some people, but for me who work with a variety of carbides that are aerospace parts, this isn't very useful to me.
