Diamond Blade Safety Guidelines
- DO - Insure the arrow on the blade
coincides with the direction of rotation of the machine
- DO - Use personal safety
equipment(Goggles, Gloves, Face, Head & Noise protection)
- DO - Use the machine guard
- DO - Insure the material is held
securely before blade contact
- DO - Guide the blade straight into
the material without tilting
- DO - Carry out a slight pendulum
movement (forwards, backwards). This maximizes the true potential
of blade speed and disperses heat build-up
- DO - Work without too much
pressure - the weight of the machine should be sufficient
- DO NOT - Make long continuous
cuts with a dry blade (carry out a slight pendulum movement to keep
the blade cool)
- DO NOT - Cut to deep in a single
pass with a dry blade
- DO NOT - Apply too much pressure
and force your diamond blade through the cut
- DO NOT - Let excessive heat be
generated at the cutting edge of the blade
- DO NOT - Attempt to cut curves
with your blade
- DO NOT - Use standard cutting
blades for grinding or for raking out mortar joints
Dry Diamond Core Drilling Guidelines
The dry diamond core drill is designed to give rapid, clean
service entries in brick and internal wall materials.
It is ideally suited for plumbers, heating and ventilating
engineers, electricians, kitchen fitters and general builders.
Using a minimum 850W, variable speed electric drill with clutch,
the coring action is totally rotary enabling the operating noise
and vibration to be reduced to the minimum.
- Pilot drill the wall first with a 13mm (1/2") masonry
drill.
- Locate the 12mm 'A' taper guide rod down through the core and
'push fit' the rod into the 'A' taper adaptor. Drill the pilot
hole.
- Use an 850-watt (min) rotary drill fitted with clutch and
variable speed control.
- Don't use hammer action when drilling with a dry diamond core
drill.
- Use machine at between 380-3000 rpm. The harder the material
and larger the diameter of core, the slower the rpm. The softer the
material and for smaller diameter cores, the higher the rpm.
Ultimately, faster rotational speeds does not always mean better
penetration.
- Make sure the chuck is tight.
- Clear swarf at regular intervals, as a build up will cause over
heating, extensive clutch wear and a possible loss of segment.
- Rotate core bit when entering and leaving hole.
- Keep machine level.
- Don't force the bit let it do the work. This will prolong its
life and reduce the chance of failure.
- If the bit starts to vibrate, reduce pressure.
