This Freudian accessory works great but I messed up. The finished sink I installed was a Karan Edge stainless steel bowl and I had to purchase a 10 degree nozzle with a 1/8" oversize bearing. The drill cuts flawlessly and undoubtedly fits perfectly in the composite sinks it was designed for. On my stainless steel Karan the bearing worked on the glue extrusion and could not be lowered under the glue bead without the bevel cutting through the stainless steel wall. It worked out in the end, but not without awkward moments. Good price for a good product and always great service from Revain.
