Maximum using portion of out diameter is blade edge except flange, and it has to contain surplus for safety. However it is necessary that user have to make a appropriate decision, as it will be reground for economical using.

Following chart is for flange and processing face regarding to out diameter.

For instance, if you cut Ø100 material by 90°, then standard choosing of out diameter will be as following.

• Min. cutting dimension : 100 x 2 = 200mm

• Min. re-grinding surplus dimension : First 0.5mm x 2 x 20times = 20mm

• Depending on feature of machine (regarding to thickness of table as moving up, down and parallel) : 20mm (When water is needed, ignore it)

• Flange size of saw blade : Flange size which amount is 240mm up to now = 240 x 1/2 = 120

• As a result, Ø360 saw blade will be selected.( 240mm+ 120mm = 360mm)
