TROUBLE WITH HOLE SAWS

A lot of people have problems drilling with hole saws. The hole saw won’t drill or the hole saw burns out right away. Here are two simple things to keep in mind whether you are drilling steel, stainless steel or wood. First, make sure you purchase  bi-metal hole saws, which are made of a stiff metal backing and a hardened tooth strip fused together, therefore bi-metal or two metals. Secondly, all quality hole saws come with a drill chart that shows the diameter of different sized hole saws along with several types of material that can be drilled. Each different type of material will require a different optimum RPM. Stay as close to the recommended RPM as possible even though it will probably seem too slow. These two simple tips will eliminate almost all problems associated with drilling with hole saws.
