It’s Project Day Tip: Drill & Tap Chart

Here’s a tip:

Print and hang up this drill & tap chart PDF in your workshop. You won’t need it for most projects, but when you do, you’ll be thankful you didn’t have to go look it up on the computer.

Why would you need a drill & tap chart? There are lots of reasons:

  • What size drill do you use for a pilot hole for a #8-32 tap? (A: 0.1360″)
  • What is the decimal equivalent of a “J” drill? (A: 0.2770″)
  • What is the imperial conversion for a 6mm hole? (A: 0.2362″)
  • I can have a loose tolerance on that #10 screw, what size drill do I need? (A: 0.2010″)
