Review on Park Tool HMR 8 Hammer Black by James Jenkins

I have a Park Tools HMR-4 rotary hammer. This is the 24 ounce version. Without thinking too much about the weight, I ordered a smaller version of the HMR-8 for a colleague. I figured this would be enough for a simple exploit. I was wrong! I also noticed that my colleague had to apply much more pressure with this hammer than if I had lent her my larger hammer. I have returned the HMR-8 and am in the process of re-ordering the HMR-4 for them.
