SLS Sintered Diamond Disk

Size: 150mm (6 inch)

If you are sick of replacing laps that always seem to be wearing out it could be time to try a sintered faceting lap. Our sintered laps have 4mm of diamond matrix and are permanently bonded to a machined steel master lap. The laps are 10mm thick in total.

You won't believe how long these laps last!

This lap likes a generous amount of water during use to flush away swarf and keep the stone cool. 

USE ONLY FOR FLAT FACETING AVOID ROTARY ACTIONS LIKE BY A GEMMASTA PREFORMER OR FREE- HAND GRINDING. A sweeping action across the whole lap surface is preferable to maintain the laps flatness.

They are ideal for those who want high volume production and long life from their disks.

A 1/2" arbor hole is standard.

Dressing can be done by using a silicon carbide fine grinding block or white aluminium oxide dressing stick. You can also dress it by using a fine corundum grit on a sheet of glass.

600# sintered lap

By: on 15 July 2022
First a disclaimer! I work at gemcuts so had the opportunity to try this out. Secondly, I’m a relatively novice faceter… I cut a labradorite and a topaz on the 600 sintered. Two really noticeable differences when compared to a plated lap: 1/ the inevitable marks left by any cutting lap seem to be of a much more uniform depth than those left by a plated 600 (even my old well worn 600). This meant a very much faster prepolish on the 3000 (copper with diamond and oil). 2/ it seems to give much sharper facet edges so that it was a lot easier to get accurate meet points. Again time saved in the prepolish was significant. Really worth considering, especially if you are cutting a lot of stones. Time saved was huge when compared with plated cutting laps..
