that's great tool i really recommended
Haven't used yet, but noticed the speed change lever ...
JAN_Opinion•June 14, 2017
Haven't used yet, but noticed the speed change lever is very difficult to rotate to change the drill speed. More after I drill my first hole! Hey, I even read the directions!!
Update 6/17/17
After two 3" & one 2" bores through 4" floor concrete, the drill worked better than I expected. The speed lever is still difficult to operate but with a little shaft rotation & gentile persuasion, the lever is movable. The clutch does work, but hang on tight! Plenty of torque! I will go from 3 to 4 stars. Would be 5 if the speed change lever worked smoothly!

We might get 2 years out of the big name brands before they are garbage. I have a trashed Diamond Products Core Bore ...

We use handheld rigs all the time. drilling 1.5" thru 8" for pipe penetrations thru concrete slabs, walls & hollowcore. Not really supposed to use a bit over 4" I believe with this unit. But they work.
Have been thru several hand helds: Diamond Products Core Bore, CS Unitec (Eibenstock), Kor-It, Core Bore WEKA, etc..
Probably tried them all. We might get 2 years out of the big name brands before they are garbage. I have a trashed Diamond Products Core Bore sitting in my office now that is about a year old.
Granted, we do use the larger bits and understand that wears the machine pretty hard, but we get almost same life span from the BlueRock.
This one last almost as long at 1/4 of price.
I paid around $1,200.00 (Eibenstock) - $1,600.00 (diamond / Core Bore) for big brand hand helds.
This is by far the best VALUE. Even if you rent from United Rentals / HERC / Sunbelt, etc.., your going to pay a couple / few hundred a week.
The water connection is a joke, but an easy work around.
If the big brand names gave us better life expectancy, would probably stick with them. But they don't - At least not for us.
