Trim a sink cutout in stages flush with the bowl using these "overhang" and flush trim bits, in tandem. The overhang bits are equipped with non-marring Ultra-Glide™ bearings that are tapered to match the slope of the bowl's side. At first pass, with the appropriate overhang bit, it cleans the cutout edge to leave a very slight overhang at the underside of the counter. A pass with the flush trim bit completes the operation.
