Is this the right fit?

Best for
anyone cutting crown, bending conduit, or setting a table saw or miter saw bevel where being half a degree off shows in the joint

The Klein Tools 935DAG is a digital angle gauge and electronic level with a magnetic base that clamps to a saw blade, conduit, pipe or any steel surface. Press zero on a reference face and every reading after that is relative to it, which is how you dial in a bevel cut without trusting the stamped protractor scale on the saw. It reads 0 to 90 degrees in four quadrants to 0.1 degree resolution, the backlit display flips so numbers stay upright at any orientation, and the housing has a V-groove that seats on round stock. Best fit: anyone cutting crown, bending conduit, or setting a table saw or miter saw bevel where being half a degree off shows in the joint.

Pros

  • Magnetic base holds it on a saw blade so both hands stay free to adjust the bevel
  • Zero button rezeros to any reference surface, so you measure relative angles instead of doing math
  • Reads to 0.1 degree with a backlit display that auto-flips right side up
  • V-groove in the base seats it on conduit and round stock without rocking

Cons

  • The magnets are strong enough to pick up steel chips off a workbench, so it needs a wipe before you set it on a clean blade

Frequently asked questions

Can I zero it to a surface that is not level?

Yes, that is the main reason to own it. Set it on your reference surface, press zero, and every reading after that is relative to that face rather than to gravity.

Will it stick to an aluminum saw fence?

No, the base is magnetic so it needs ferrous metal. It holds on steel saw blades, cast iron tables and conduit, but not aluminum or plastic fences.

Does the display stay readable upside down?

Yes, the screen auto-rotates so the number reads right side up whichever way you seat the gauge.

What batteries does it take?

It runs on AAA batteries and has an auto-shutoff, so it will not drain sitting in a tool bag.
