I know the old adage of buy cheap buy twice is true for a lot of things, but any money handed over for these drills is literally a waste of money. The smaller drills are already out of true, but I've experienced that before. The worst thing about these are that the counter sink part is held on by a small Allen bolt, which cannot grip the shaft of the drill and you can't tighten them up without rounding off the hex part of the head. I'm not ham fisted with any tools, but these have self destructed on the first couple of goes. Awful, awful product.

they seem OK only problem I have with them is they turned up with no allan key,lucky I had one so dont let this put you off

Low quality, the countersink adapters just fall off and require repeated tightening. The bits themselves very weak and snap easily

The drill bit instantly bent on drilling into plywood, utter rubbish and avoid like the plague. Can probably guess which country this came from...

One operation of hole drill and counter sink for screw heads.

Wish I had read previous reviews, used the smallest drill bent immediately just on soft wood how they can claim High Speed Steel is beyond me. Given it two stars because I have not tried the larger sizes which must be better.

The smallest drill bit collapsed when the lightest amount of pressure was applied. The countersink parts do not cut well as they are blunt. The grub screw holding the countersink cutter is weak and doesn’t hold properly.

Not very sharp.
