Don't worry about them falling apart as you are coring, just keep enough water on the operation. By the way, Hitachi does a terrific job with there concrete hammers, drills, breakers. etc. Fair prices, very durable tools. Enjoy! :pepsi:
Great news! I was affraid of turning something this big, with just a friction connection. Yep, I got a pilot bit for it already.
I have a BoschHammer Model 11222EVs, that is fantastic. Its about 5 years old. And I have been taken for a ride or two, on my Milwaulkie Hole Hawg. :woot: MORE POWER !!!!!
