How to fit a hole saw to my electric drill?
Question:
Answers:
Most holesaws come with a center bit that the holesaw blade attaches to. That center bit should fit into any standard drill chuck.
When you go to buy the holesaw, make sure it comes with a center bit. Sometimes they don't. If it does not, you'll need to buy one that fits the holesaw you select.
If you buy a holesaw kit, such hardware should already be included.
