DIY Tip of the Day: Enlarge a Spade Bit Hole. If you’ve ever drilled a hole too small with a spade bit and wanted to redrill it to a larger diameter, you know the meaning of frustration.

Hold the drill firmly as you carefully expand the hole.

The Family Handyman DIY Tip of the Day: Crafty Caliper. Combine a try square and a Speed square to measure the diameter of round objects.
