【Echo Tech】 Uploaded new video, “Remove rust on grinding stone” on YouTube!
This time we used Grinding stone to remove rust stuck on screwdriver.
We have 9 different hardness Grinding stone for each bar and plate type.
Plate type is useful for polishing flat face, and could work powerfully.
Grinding stone could use both edge side(black part), so when colored part get broken and shape changes, you could keep use, by setting up side down.
For using grinding stone, do not use with High or S-High power mode.
Otherwise, the blade will burn and get easily broken while doing work.
If you have any questions or comments, please send us message here.
