Thread: 1k Chosera or 1k King Stone

DMT, work fine, but the CKTG is 400 and 1k for half the price. They last just as long as the DMT and produce much the same finish, at the same grits.

The D8E is about 1200 grit, you will still need a 3-400 grit for heave stock removal and as said use to lap your stones.

That seems a bit pricy for the D8E, which can be found for about $50-60.

The CKTG plate, I believe is the I Wood dual plate and can often be found on Ebay for about the same $35 price if shipping is an issue.

MICRON (μ) is the letter "micron" in the Greek alphabet. As measuring unit it describes 1 thousandth of a millimeter (1 μ = 0.001 mm). A Micron row is added to each FEPA P, FEPA F, JIS und ANSI row for comparison.
MM Micro-mesh grit in comparison to other standards.
The grit sizes are defined by the number of lines per inch (25.4 mm) length of each sieve e.g. 150 lines per inch. Abrasives grit 150 will pass this sieve. This chart is a general overview only. We are not responsible for any errors.
