User questions & answers

Question:	Is the side handle available and what thread size is the handle
Answer:	The Thread Gauge says the Pitch is 2.0 mm but the size is odd at 15.86mm
Question:	Why only a two wire 16 awg power cord? (i am a little afraid of mixing water and electricity even though using it on gfi protected outlets
Answer:	That is a good question... I just used this drill with a 3" core to make a hole in a concrete wall 6" deep and worked well, was slow but I went through TWO metal rebars. Don't put to much pressure on the drill, it may lock the core and turn the drill and your hands will go with it... The amount of water needed was not going to the core drill and to help it I had to put the bucket of water in a position higher than the drill and at the same time help it with a water bottle, sprying water at the same time to prevent the core from getting hot.
Question:	Price of 1/4" and 5/16" bits for this drill
Answer:	No for these small sizes under 1 inch use a hammer drill or with SDS. The smallest core drill size I've found is 1 inch
Question:	How do you get the holes started without a stand
Answer:	You can hold it at a slight angle just for half the bit starts cutting . Then start to straighten out. It works I have drilled three inch holes on top of a 10 ft ladder.
