A complete spot weld removal solution consisting of a 3/8-in. CutterAssembly, five Replacement Cutter Bits, a Replacement Center Drilled a 5/16-in. Cobalt Drill Bit.
The cutter component includes double-ended bit, centering drill and non-slip hex shank. The long-life bit threads onto the hex shank and is quickly reversible. A center drill inserts into the shank and is held securely with a setscrew. This non-walking drill point pin keeps the cutter centered over the spot weld. Cutter bit and center drill are also easily replaceable on the job.
A cobalt, steel drill bit option features a self-centering, non-walking, shallow design. Removal of spot welds by this method is accomplished without drilling through both joined metal panels. The squared-off drill bit tip leaves a precise, clean hole only in the panel to be removed. Remaining panel requires minimal surface grinding.
