Works As Specified - Power Tool Parts & Accessories

These bits center and countersink wood reasonably well without damaging the finish. The adjustability is a great feature. So far I've only used them in softwood (pine) so I'm not sure of their longevity or durability or use in other materials, but so far so good. I am happy with this purchase so far.

Pros
  • Power & Hand Tools
Cons
  • Available in Black Only

Pretty good set but metric tools need a retooling

This is a pretty good set for the money but the downside is that it's metric and requires rework to do the hard work. I have about 4 years experience in Europe to give you an idea of the dimensions but that's been quite a while in service. I've found that most of the time I just put the head of the screw next to the sink for comparison and mostly drill out successfully. Bits are adjustable in length and can be easily replaced if they break. A low collar would be a nice addition to the set.

Pros
  • Countersink
Cons
  • Not as thick as other picks

SOME DRILLS ARE NOT STRAIGHT

I ordered this 7 piece set (each drill bit is a different size) for my husband as he is very handy and likes to do small projects around the house. Countersinks work well, but drills not so much. The reason he doesn't like the drill bits is that they aren't perfectly straight, some of them are slightly curved so he put his own drill bits into the countersinks that came with the kit and found they worked very well. better for him. However, they are affordable, so I think if perfection is not…

Pros
  • drill bit
Cons
  • old
