Conclusion

There are a few things to keep in mind when countersinking bits for wood. First, the bit should be slightly larger than the screw being used. Second, the bit should be sharp and have a well-defined cutting edge.

Third, the bit should be set at the correct depth. Finally, the bit should be run at a slow speed.

If these guidelines are followed, countersinking bits for wood will produce clean, consistent results.
