Frequently Asked Questions (FAQs)

1. What are hex shank drill bits for?

A hex shank drill bit will be used in conjunction with a drill press. A hex shank drill bit is a cutting device designed for use with a drill, drill press, or other rotating instrument.

2. Can you use hex shank bits in a drill?

The answer is no. As explained, regular drill bits are not designed to withstand the stress of the torque an impact driver outputs. As a result, if stress-tested, regular drill bits with hex ends placed in impact drivers can easily snap which could also break the impact driver itself.

3. Can you countersink with a regular drill bit?

Another improvised way to countersink a screw is to drill your pilot hole with your regular drill bit and then use a Phillips head bit to hollow out a countersink divot to a depth where the screw head can lie flat. This method furnished a surprisingly clean-looking hole.
