**220T640 is for Holz-Her 220mm panel saws.
An engineering breakthrough that emcompasses the same features as our regular melamine saw blade 'MB' & 'MSB' Series, but the long lasting Ditec™ carbide tips. Recommmended for anyone who cuts melamine on a regular basis.
Instructions for grinding:
• For maintenance grinding, use fine grit (D400 to D600) diamond wheels. To match the factory grind, use a slower than normal feed rate.
• Damaged teeth can be replaced, however, replacing of a large number of teeth will, of course, shorten the life of the saw blade.
• Since the carbide in the DITEC™ is harder than other carbides, it is critical that you protect them from “thermal shock” if an adjacent tooth is replaced. Heat absorbed during the brazing process will seriously degrade the DITEC™ carbide.
