57155 Carbide Tipped Sink and Trim with Ultra-Glide Ball Bearing Guide Solid Surface 49/64 Dia x 1-1/2 x 12 Deg x 1/2 Inch Shank

This bit is designed specifically for use for the Karran stainless steel edgesinks for laminate and 1/2" solid surface materials. They trim the counter-top edge after the bowl is mounted.

Trim a sink cutout flush with the bowl in stages using these "over-hang" 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. A first pass with the appropriate overhang bit cleans the cutout edge, leaving a very slight overhang at the underside of the counter. A pass with the flush-trim bit completes the operation.
