Klein Tools 935DAG Digital Electronic Level and Angle Gauge, Measures 0 - 90 and 0 - 180 Degree Ranges, Measures and Sets Angles

Very accurate - much more than expected. Excellent for adjusting saw blades, fences, jigs, etc. The magnet is extremely strong - so much so that even when placing gently against a saw blade, it will still bang against the blade. At first I was concerned this hard bang would throw off the calibration, but even after a hard drop it still zeros out on the reference surface. Super easy to use: place on the reference surface, zero and place against angle surface to check angle. Only thing I wash it did was allow any angle to be set as a reference. It will only zero close to 0.

This tool is great for leveling, providing quick, precise measurement and a nice visual indicating the direction of the current angle. The angle gauge works great for setting the Altitude for an equatorial wedge, and the magnet in the bottom helps it stay in place when measuring. We have two, and their measurements are consistent. When measuring a surface leveled with a reliable bubble level, the 935DAG typically shows 0 degrees of tilt. (Occasionally we'll see 0.1 degree, but that might be the actual surface angle. This has finer precision than the bubble level.)

Battery life is great has a strong magnet that’ll stick to your blades with ease. Lightweight and good quality. I use it everytime now when I adjust my blades and have no complaints. Comes with a little Velcro pocket to store it in as well which is nice.

The Klein Tools 935DAG Digital Electronic Level and Angle Gauge has been an excellent tool for precision work. I primarily use it with my knife sharpener to make sure I’m getting the exact angle on my blades, and it’s made a noticeable difference in consistency and sharpness. The digital readout is clear and easy to read, and it quickly measures both 0–90° and 0–180° ranges with accuracy. The magnetic base makes it easy to attach securely, and the compact size means it doesn’t get in the way while sharpening. ✅ Pros: Accurate digital readout for precise angles Measures 0–90° and 0–180° ranges Magnetic base for secure placement Compact and easy to handle Great for sharpening, woodworking, or general leveling tasks ❌ Cons: The small display might be harder to read in low light Requires batteries (included, but be sure to keep spares) 💡 Tips: Place it on your knife sharpener’s guide to ensure perfect sharpening angles. Store it in a safe spot to avoid dropping, as precise tools can be sensitive. Works great for other uses too — like setting angles on saw blades or woodworking tools. Always calibrate before use to ensure maximum accuracy. Bottom Line: The Klein Tools 935DAG is a versatile, precise, and reliable angle gauge. It has made my knife sharpening far more consistent, and it’s a great tool to have for any project requiring accurate angle measurements.

Worked fine used three times... And it was stolen from me. Grrr. Lol

Small but rugged, accurate, and easy to read! I have used it on my table saw and to align my miter saw and it was supper easy. I verified the alignment and it was exactly right on. The magnetic base is the real deal. No slippage when I have used it for metal electric conduit. Overall, I am extremely happy with the unit and I highly recommend it.

This little box has already earned its place in my tool bag. I’ve used it to calibrate my table saw blade, miter gauge, every reading matched up perfectly with my mechanical protractor. The magnets are strong enough to hold steady on the blade without sliding, and the backlit screen is easy to read, even under shop lights. The zero function works great when you need relative angles instead of just absolute. Battery life’s solid so far, and it boots up quick. It’s small, rugged, and gets the job done without overcomplicating things. If you’re tired of guesswork or squinting at analog bevel gauges, this one’s worth every penny.

I use this to check the angle on my Ruixin Pro and it works perfectly. I like the ability to Zero out to get an accurate aggregate reading. It has leveled up my knife sharpening skills for sure. I spent a little more for the Klein as it is USA made and am sure the quality is better. We have a Klein plant in the city I live in.

Good quality. Great magnets. Sturdy little tool.

Perfeito

I’ve used this for 1.5 years and now it would not power up despite many battery changes.

ممتاز

Great little tool to have. I've used it for finding the pitch of my garage, setting my table saw, chop saw and drill press.
