Good design. Says “50H” on mine. Runs at 120V/60Hz. Measured 670 RPM no load. Gear ratio: 25.06:1. Zero internal electronics (no soft start circuit) or SCR speed dimmer - WYSIWYG. Power was properly grounded to the body. I like that the carbon brushes are easy to access. The internal fuse wire was a bit exposed but easy to fix. It’s a super simple drill with decent gearing. Use with a VFD instead of getting a speed-variable one if you understand how universal AC motors slow down and keep torque.

I bought this thing almost 4 years ago, works like a champ. I have only two issues with it, neither that would make me not but it again, but, the lubrication method for the head and the spring loaded pin for slug removal isn't much and causes a huge mess with excessive oil consumption and then there's the noise the motor makes. I suggest wearing earplugs, I certainly do. Other than that, I use mine all the time from overhead to horizontal without any issue. I would definitely buy it again for the price I paid. It's paid for itself a long time ago.
