Model 5268-21, 1 1/8" SDS-Plus Rotary Hammer.
Used it to drill quantity 21 10"deep by x 3/4" holes for setting sill plate anchor bolts and seismic hardware with the Milwaukee bit.
On the 22nd hole I hit rebar; stopped the drill from going any further, but it did not bind.
Picked up a 3/4" Diablo rebar cutter bit. The bit was working, but after about 1/2" of hard progress (I thought I was almost through) the drill started smoking. Stopped drilling and set it aside. Was still smoking, and getting warmer, even though it was unplugged. 10 minutes later it was still hot. By now it was about 10 pm, and I needed to get to bed. Took it outside and set it on the pavement 20 feet from the house in case it burst into flame.
Came back in the morning; it had not burst into flames. But it smells like it. Plugged it in, and it drilled the final hole I needed to get done - without rebar, no problems. I'm still going to try and exchange it; this should last longer than 22 holes in concrete, even if one was cutting rebar. If I can find the &^%$# receipt.
