Product Description

RSCNBC-1 3/8 inch

Our 1 3/8 inch CNC core bit has a tall, super-thin rim. It blazes through the hardest stones without blowing out the bottom of the stone. This tool will cut hundreds of holes, not dozens. Standard size is 1 3/8 inch diameter; many other sizes available on request.

RSCBCCB-1 inch

Rockstar’s “clean-up” finger bit is the RCNBC-1. This 1 inch diameter bit is vacuum brazed with 50 grit diamonds and is a great tool for smoothing inside sink cut outs.
