INFO:
The set includes an aluminium storage case for transport.
The Bi-metal hole saw's fast cutting power lies behind its HSS (hi-speed
steel) manufactured teeth.
The teeth have been set to a variable pitch to
improve harmonic vibration and to have a better chip clearance.
The hole saw can be used to cut into:
The Bi-metal hole saws are primarily used by electricians, plumbers,
machinists and carpenters.
Lubricant tip:
Use paraffin or beeswax when cutting into aluminium. Use
CT-90 or a general-purpose lubricating oil when cutting into steel.
To use a hole saw, you need the following accessories:
IMPORTANT:

TIP:
When using a hole saw for wood, clamp an off-cut backing board on the
back to prevent tear out when the hole saw exits the material. The backing board
also prevents materials from flexing.
