Typical
Applications |
| |
 Notching
Cutting
sheet metal
Pipe cutting
Foundry gate/riser removal
Metal plate dimensioning
Bar cutting |
 Run
wheel at the highest possible speed (marked
on the wheel)
It
is recommended that a cut-off machine should
have 1 HP for every 25 mm of wheel diameter.
Make
cuts as quickly as possible.

Reinforced
Cut-off Wheels
Designed to resist breakage caused by severe cross-bending.
A reinforced wheel is required on any operation where
the work is not securely clamped.
