Good tool. I have the 1800 rpm unit and the bit ran true so it was relatively easy to start the hole with a smooth running machine.
Once the hole the hole was started I went through 14″ of concrete in 10 minutes.
The ways and wear surfaces on the movable part of this drill press are well done.
I bought a garden-hose-thread to 5/16″ hose barb adapter from Lowe’s and used a valve at the hose end to control the flow rate. The pressure at my site was too high for the flimsy hose provided, so I cut the pressure down before the little hose.
Happy camper.

Delivery was great. The price is phenomenal.(the last one I bought back in 2004 was an Ebianstock and that cost me around $1300…. so 250 is pretty sweet! That all being said do not I repeat do not lock the trigger!!!!! this is not like your traditional horror drill. There is no clutch so when it hangs up, you’re gonna go for a ride… I know because it almost knocked me the fuck out!!! my fault not the tools!

The drill worked great for 5″ boring on block walls dry and a 14″ wide concrete wall wet. The hose connection and tubing that come with the drill for wet use do not connect to any US connections. You have to get your own adaptors. The shoulder rest screws in with the rubber cover removed and that is not clear in the instructions. It also needs to be removed for the drill to go back into the plastic carrying case. Bottom line it worked great and exceeded my expectations.

BUYING ANOTHER 2 JUST TO HAVE THEM.

Product is perfect for what we use it for. Coring 2”-4” holes to set handrail posts. Highly recommend
Only issue is getting what is needed for the constant water flow hook up but manageable and still works great

Works great! Hard finding attachment for water feed though.
