I had to drill 32 1/2” holes in a double frame truck frame on a truck I was building. The price of this drill was the same as renting one over the weekend. This seemed cheaper in the long run and if it survived the job I considered it pretty much free after that. It’s a Chinese drill but quality wasn’t too bad. I had to double check and tighten up a few loose screws and check a few connections with the on/off switch but other than that and a pack of cheap mag drill bits we were off and punching holes through truck frame like it was nothing! I use a much more expensive unit to line bore and sleeve semi truck axles at work and this unit did the job just as well. Magnet seems strong but doesn’t have any safety features to shut the drill off if the magnet comes off the metal surface. Just take your time and don’t put too much pressure on the drill. The “safety chain” that came with the drill was a piece of rope. I chuckled at that idea and used a scrap piece of light chain I had laying in the shop. I didn’t think much of the Oiler setup on the drill and after listening to the Oiler squeak for a few minutes took a set of snap ring pliers and took it off and manually lubed the cutting bit with a oil can. Highly recommend and would buy again even though unit seems to have held up very well so I doubt I’ll need to.
