Clipacore Condensemate puts you in control when upgrading from overflow pipe to 32mm waste pipe (or larger). 
The 300mm long core bit supplied, simply inserts into the existing open 22mm – 25mm hole (pipe fully removed). Once the outer core bit has scarred the wall, the inner long core bit serving as a guide can be removed by hand.
Our easy to use design ensures consistently symmetrical holes eliminating the risk of core bits skidding off course and damaging the wall. The inner spring loaded core bit removes the need for tools thus improving workflow efficiency every time.
The 22mm core bit can also be used on its own (with our smaller quick release core adaptor) to prevent blowing the brick face or render wall,  compared to using a 22mm SDS masonry drill bit on hammer action.

a) Perfect results are easily achieved by using any rotary drill with a minimum drive power of 850 watts. The machine should also be capable of speeds of up to 3000 rpm and have a variable speed control and slipping clutch.


b) Clear the debris at regular intervals, as a build-up of dust will cause overheating, extensive clutch wear and possible loss of segments.


c) The harder the material and larger the diameter of core, the slower the rpm.


d) The softer the material and for smaller diameter cores, the higher the rpm.


e) Reduce pressure if the bit starts to vibrate.


f) Do not – Use hammer action when drilling with a dry diamond core drill.


g) The inner core bit supplied serves as a guide only for the outer core bit, so always ensure the overflow pipe is fully removed within wall before drilling. The 22mm inner core bit MUST insert within the existing hole without any force or resistance to prevent the spring compressing from the high torque load.


We take no responsibility or liability for any damages or failure arising out of, or in connection with misuse of the product. Should damage occur to the diamond segments (separated from the barrel), please send photographic evidence of the core bit and the hole being drilled for examination by our technicians, to: [email protected]

What do Engineering Bricks look like?


Engineering Bricks have a smooth finish with perforations through the top to the bottom. They are widely available in blue or red and are identifiable by their uniform shape.


Class A engineering bricks have a higher compressive strength over class B and are harder to drill.
