Cone-an (3mm - 75mm) Countersink

Ranging from sizes 3mm to 75mm, this double sized countersink bit replaces our older versions of the countersink bit and can help to increase hole size as well as dress the edges of previous cuts that may have imperfections caused by drilling/cutting.

The fine diamond grit is perfect for helping to gently increase the size of holes and/or dressing the tile.
