The Best Jamb Saws for Your Next Home Improvement Job

When installing flooring, there can be some tricky spots to access and get perfect, one of them being door jambs. You’ll want to get the flooring pushed beneath the door casing to make it look flush, complete, streamlined, and professional. To do this, you’ll need a jamb saw (also known as an undercut saw). Here are some of our favorites.

What to Consider in a Jamb Saw

If you’re purchasing a jamb saw, consider these features:

  • Depth of Cut: Make sure you have an adequate depth to slide your flooring in.
  • Adjustability: You’ll want to have depth control capabilities, so you can adjust the depth according to the project you’re working on.
  • Power: More amps will mean more power for longer.

Top Choice: Crain No. 575 Multi-Undercut Saw

This electric jamb saw from Crain is a great saw that’ll get the job done. It’s a 7-amp saw that can cut from flush height to 1 inch. Depth-wise, it cuts from 1 inch to 1/4 of an inch and has a dual-angle depth gauge for straight cuts or cuts at 45-degree angles.
