Arbor Holder with Pilot Drill | Thread 1/2' x 20 - 6mm 5% Cobalt | Hole Saws 14 to 30mm

Optimum quality/value ratio,Two types of thread,Resistant to breakage,Easy fitting to the cranean saw,Long tool life,The fittings/shrouds are solidly constructed to sustain the pressure exerted by the power tool, making it so that there is no loss of energy in drilling and the cutting process is continuous.
It is important to bear in mind that the Crank Saws should be applied at a 90º angle to the contact surface.In situations where the workpiece has no support, it should be held firmly in a clamp or vice, to prevent it from being displaced, thus avoiding its breakage or rotation together with the Crane Saw.
