Lens Harpoon #2086


Diamonds Are A Hole’s Best Friend?

You drill a hole for a rimless mounting through a lens. Looks good and clean. You mount the lenses and down the road jobs are coming back because there is cracking around the holes. Big problem. Easy solution. Use this tool to chamfer the hole to eliminate a pressure point from developing. Diamond tipped conical point mounted in a carbon steel nickel plated handle.
