What makes a good countersink bit?

A good countersink bit is one that helps you get the job done more efficiently.

  • You might like to drill your pilot hole and countersink in one go – in this case, you’ll want an all-in-one countersink bit.
  • If you need to drill a lot of holes, you might like to have a depth stop in place to ensure you’re hitting a consistent depth, every time. You’ll therefore need a countersink bit with a depth stop.
  • You might be using lots of different-size countersink bits on a given project. Therefore, you might want a bit with a hex shank rather than a round shank to make it easier to change over.
  • If you want to be able to make counterbore, in order to use a plug to cover the screw for example, you’ll need a countersink that’s the right shape. Specifically, it should have a flat (non-tapered) part at the top, to allow for a straight counterbore to be drilled after the countersink is complete.

For different people, different countersink bits will meet your needs better than others. This is why it’s so important to carefully consider your needs before buying.
