‘S’ Type Bradrad® drills are used to machine a wide variety of materials and for many different applications. No pilot hole is required, and good quality deburred holes are produced with minimum of fuss using a bench drill or light pedestal drilling machine.
‘A’ Type (HSS Cobalt) Bradrad® drills incorporate a detachable centre drill and the first diameter is produced by a smooth trepanning action. Thereafter, the ‘A’ Type drills from step to step until the required diameter is achieved. The initial trepanning action produces a disc which must be removed before commencing the next hole.
‘B’ Type (HSS Cobalt) Bradrad® drills incorporate a detachable centre drill, and the first diameter is produced by an ‘end milling’ action which ensures the rapid penetration of steel plate or structural steel supports.
‘F’ Type (HSS Cobalt) Bradrad® drills require a pilot hole which can be produced by an ‘A’ or ‘B’ Type Bradrad®, some other drilling method or even by flame cutting.
