Yamato Seitosyo Corporation
Yamato Seitosyo Sakura Oilstone

Manufacturer: Yamato Seitosyo Corporation
Model: Square
Feature
- The grain size is equivalent to medium #280, fine #600, and extra fine #1000.
- The bond is a vitrified clay-like material impregnated with solid oil, and the extremely high degree of bonding (HRH100-115) makes this whetstone less likely to lose its shape.
- Whetstone dimensions can be made in any shape, from 4-inch and 6-inch square whetstones to comb-shaped, square, triangular, and round sticks.
- Specifications include deburring, chamfering, surface correction and finishing of molds, and more (a wide range of uses).
- Since it has been oil-treated, it feels smooth even when used as is, and if it is used with a little grinding oil, the work efficiency will improve even more, and will achieve a higher precision finish than conventional oil whetstones.
- Because it is a flammable solid, be sure to dry the whetstone naturally. It may cause a fire.
