Thank you! I was using a diablo spade drill bit and it seems too work but not great.
So something like this? https://www.amazon.com/dp/B00004RGZI/ref=cm_sw_r_cp_apa_glc_fabc_JRQJG060MXZY2YRP2279?_encoding=UTF8&psc=1
I have a regular dewalt drill and a Dewalt impact driver. So for the regular drill what do you mean thr second handle? There are 15 speed digits and then 1 and 2 on another dial. Do you mean keep it on 2 on the dial? What of speed?
By the way I never got a notification about your message till I was going thru old posts.
