Rubi Tools MULTIDRILL Drill Bit Guide

Great guide! The only issue I see (and could use a design change) is the water tube connector sticks straight up. This causes the drill head to rub on the hose when using small dia. bits. What I've done to remedy this issue is the wrap the hose around the suction cup handle after I lock it down. Since I do restroom partitions and accessories like HC grab bars most of my holes are either 1/4" or 5/15". I'll drill up to 100 holes in a pair of public restrooms a day. This guide has really been holding up. Unfortunately the little red plunger handle on the top of the water pump disintegrated on the first day. Very thin plastic on a metal post. But still works well.
