Mike Yaross Field Verified

Just what I needed

"Saw works great. Just what I needed. You may want to update the specs though. It says 110v but it’s 220v. I don’t think it will an 10” saw blade either. Haven’t tried but I don’t think it’s set up for one like it says. Ordering process was nice and easy. Thank you."

FRANCISCO, Shop Manager Field Verified

Built for 24/7 Production

"Got the JLT #717C for our shop and it’s an absolute beast for narrow stile doors. The 2-second squaring cycle is legit—we’re easily pushing 100+ perfect doors a day now without stressing over glue joint alignment. Setup is super fast with the pin system, and the heavy-duty build takes daily abuse without losing accuracy."

Quiet, Fast, and Totally Worth It

"Bought this California Air Tools compressor for the shop and it’s an absolute game changer. It’s incredibly quiet—you can actually have a normal conversation right next to it without yelling. It fills up fast, keeps up with all our nailers and blowguns with zero issues, and the oil-free pump means no maintenance. If you're tired of loud, annoying compressors ruining the vibe on your floor, grab this bad boy. Worth every penny."

Heavy Duty & Precise

"Brought this Jet 16" x 40" Engine Lathe into the shop recently and it’s an absolute beast. The 3-1/8" spindle bore is exactly what we needed for turning larger bar stock, and the geared head runs incredibly smooth from 25 all the way up to 1,800 RPM. It handles our heavy daily metalwork without breaking a sweat, and you can see how solid the build is right in the photo. If you need a reliable 3-phase lathe that holds tight tolerances all day, grab this bad boy. Worth every penny."
