Review on Spyder 600083 Rapid Eject Bi Metal by Dwayne Pore

best hole saw i have ever used stating i don't like the center drill firstly the shank is too long so i have trimmed it off and lightened the edges with a bench grinder which shortened the entire rig by at least 2.5 inches, shank and pilot drill bit are one piece and also too long waiting to be crowned again by the dill doctor.
