Than a good hand drill is convenient to operate in tight spaces. But needed a drill of a different size or required stronger tightening Chuck, and have to return to the tool shelf… isn’t it better to fix any of the drills and the key to the Chuck directly into drill? To do this, from car or motomeru cut two rubber rings and worn on the body one by one. The outer ring securely hold small tool at any position drills, and the inside will protect the coating from damage.
