Diamond cutting discs
MAKITA diamond cutting discs meet the highest demands
in working safety, ease of operation, and economical cut-
ting performance. They can be used for cutting all materials
except metal.
The high durability of the diamond grains ensures low wear
and thereby a very long service life with almost no change in
disc diameter over the lifetime of the disc. This gives consistent
cutting performance and thus high economy. The outstanding
cutting qualities of the discs make cutting easier.
The metal disc plates give highly concentric running for minimal
vibration during use.
The use of diamond cutting discs reduces cutting time sig-
nicantly. This in turn leads to lower operating costs (fuel
consumption, wear on parts, repairs, and last but not least
environmental damage).
SPECIAL ACCESSORIES
Pressurized water tank
To keep down dust and for better cutting-disc cooling, MAKITA
offers several options for wetting the disc during operation.
The pressurized water tank is connected to the Power Cut by
the water set on the protective hood.
