File Chamfer and Swarf Tools

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.

General file for working on flat plastic frame surfaces.

Fine cut, 8″ long.

Use for reaming holes in rimless lenses, etc.

Fine cut, 5-1/2″ long.

Create a driver blade slot in the head of a screw.

Fine cut, 4-3/8″ long.

Alter the angle of the temple to the end piece on plastic frames.

Coarse cut on wide side while beveled edges are smooth to prevent accidental damage to eyewear. 7-1/2″ long.

You clipped the excess off a screw and are left with a ragged end.  In oldie days you’d reach for a riffler or spoon file. Too often the file would slip off the screw and drive itself into the frame or lens.

Now you don’t have to take that chance. A few twists of this tool’s cupped serrated cap will safely round off the ends of cut screws. The working end is made of hardened carbide steel permanently mounted in a carbon steel nickel plated handle.

Works on screws with a maximum diameter of 1.6mm. Also use to smooth the ends of cut temples.

Modern lens material is very soft and during the edging process there might be a little swarf remaining where the bevel meets the surfaces. You want to remove this excess material and not run the risk of scratching the lens.

The curved edges on this blade help keep it balanced on the edge of the lens. We built in fine, squared tips for cleaning out the groove of a nylon cord rimless.

Made in the USA of spring steel mounted into a carbon steel nickel plated handle.
