The BL quality Aluminium Oxide BLUE has been especially adapted to ameliorate the performace of the grinding wheels on shaft in a small diameter which rarely turn at a sufficient speed.
The grinding wheels presented hereunder are manufactured with a VITRIFIED BINDER to use between 35 and 50 m/sec., so Ø25 mm = 25.000 rpm = 35 m/sec.
EXCEPT for the grinding wheels L02/237, L02/262 and L02/275 with a BAKELITE binder to use at 45 m/sec., so Ø 40 mm at 22.000 rpm.
The grinding wheels L02/068, L02/112 and L02/172 have a total length of 100 mm.
