Klein Tools 935DAF Digital Angle Finder, Precision Measurements, Miter Saw Protractor Angle Calculation and Portable Design

I bought this to check the blade angle on my lawn mowers, and it works VERY well. I feature a lot of mower reviews on my YouTube channel @LawnandOrderTexasEdition, so having a precise, durable tool like this really matters. The white-on-black display is incredibly easy to read — even in outdoor lighting — and the accuracy seems spot on. The metal rulers feel sturdy and give the tool a solid, professional-grade feel. It doesn’t feel cheap or plasticky like some others I’ve tried. ✅ Accurate readings — perfect for blade leveling and angle checks ✅ Bold white text on black screen is easy to read ✅ Metal construction feels like it’ll last forever ✅ Runs on a single battery If you’re doing blade maintenance, deck leveling, or fabrication, this is a tool that just works. I’d absolutely recommend it to my friends and fellow DIY lawn guys.

Fantastic gauge for all kinds of projects. I’ve used it on deck handrails and crown. Works great and love the miter button!

Easy to use!

A quality tool with easy to read graduations and an easy to use angle finder. Digital LCD is easy to read in artificial light. Don't think it was wise to use the same button for on/off and zero reset. Long press for on/off, short press to re-zero. I'll get used to it over time, but I must have reset zero when the rule was not at zero the first 15 times I turned it off. Anyway, other than that, operation is smooth and intuitive. Accuracy is perfect as verified with carpenter square, protractor, and miter gauge. Packaging is horrible and dangerous to open. Gotta keep all those Amazon warehouse shoplifters at bay!

This digital angle finder has become one of my most-used tools in my fabrication shop—hands down. I’ve tried other brands, but they couldn’t measure up. I sent them all back. But this Klein tool is a different story—it’s precise, dependable, and incredibly easy to use. Whether I’m building trailers, fabricating spiral staircases, or welding custom handrails, this angle finder has been a game-changer. The accuracy is spot-on, giving me the confidence I need when measuring complex angles. Adjustments are fast, and the digital display is easy to read, even in less-than-perfect lighting. If you’re serious about precision in your fabrication work, this tool is absolutely worth every penny. I can’t recommend it enough.

Bulletproof. Has been ti hell and nack and still works great!

Klein, thanks for wasting my time with absolute garbage; not once, but TWICE. Read all the 1-star reviews and a common theme occurs - poor repeatability. I'm appalled that Klein would sell something of utter junk like this. They've lost my future business of any product; literally. The first scale I ordered would not return to zero precisely (+/- .5deg), which is unacceptable, considering my old General angle finder is 99.9% repeatable. Amazon was polite and sent me a replacement; however, it also failed to even return to its own zero (+/- .2 deg). I measured a precision 90.00deg machinist setup block and both these Klein tools showed about 91 deg. Klein says the accuracy is +/- .2deg, but that should never occur simply going back to its zero. The built in encoder is likely junk, as you can move each end of scale about 1/4 deg without the display even recognizing the movement. Coincidentally, inside both Klein battery covers was the same build date 0326; likely their Vietamese QC is slacking, or doesn't care and passes them. On a positive note, the display is fantastic and the build quality is high (no metal burrs, clean plastic edges, great laser etching, good weight/heft, AAA battery). If you intend to use this gauge for any precision work (i.e., metal fabrication), be warned and test, test, test before the return windows closes. Personally, I'd not waste your time and select something more reliable.

Very nice angle finder and has a miter gauge button also. Well worth the buy

I do a lot of woodwork and needed an accurate angle finder and as always Klein deliver there products are well built and made to last and so easy to read so yes I’m very happy with my purchase

Very impressed with the Klein tools Digital Angle Finder. Klein always makes amazing tools. Build in Vietnam. If you want a great angle finder to save you a bit of time this is a great tool for the job.
