OFF TOPIC: MAGNETIC DRILLS

I think two important factors are amount of chatter from the head, and the strength of the magnet. I don't have any American-made info for you but I bought a Chinese mag drill a couple of years ago and it did the job for me but it's definitely not professional quality. Takes a lot of prep and consideration to get it to produce a good outcome which is ok for me because I have (some) time but I'd never use it in a pro shop.

Milwaukee with a movable/adjustable base.

I really like my Milwaukee unit with movable mag base. Bought it used several year ago and it is my go to unit for line boring drive plus making holes. Be sure to pick the right rpm capacity (two speed) units if your going big holes and cylinder honing.

Agree with the others that the Milwaukee mag drill is an excellent drill. I have used the Milwaukee and own and use the DeWalt DWE1622K mag drill and both performed very well in tough conditions.

Another vote for the Milwaukee mag drill with the adjustable base, two speed motor and adjustable speed on the base, along with the Milwaukee Steel Hawg cutters and arbor. I use both the special arbor for the Steel Hawg cutters and the Jacobs chuck for twist drills, really nice that you can set the just the right speed for each hole size and material, and the arbor has through hole coolant capacity, with that combination the cutters last a long time and makes drilling easy, I have the 4203.
Only drawback, it's heavy.

I've had a 3/4" chuck Milwaukee Mag drill for 30 years. I replaced the chuck a dozen years ago when it started to slip after years of abuse. I use an Yancy slugger adapter in it for the larger holes. I have drill up to 2-1/4" several times. Never had a issue or lack of power at any speed with it. It is a all steel heavy old bugger compared to todays similar models. It was $1,200.00 then and a couple years ago they were still $1,200.00.

buy a low profile one,very handle on truck frame and machinery.

We have a magnetic evolution drill, we used it for drilling out the bolts in the wing mount on the JD grader and I believe they were 5/8. I believe it is made in America if I remember. The only problem we had is if we try to dig in to fast the magnetic connection breaks and if the bit is stuck in the bolt hole it gets a bit scary. We also had broken off normal drill bits in the holes and it went though those
