22m / 28mm / 42mm / 52mm / 127mm / 152mm XPRESSCUT is perfect to work alongside DUOCUT when enlarging existing holes within a wall for larger waste pipes, larger gas pipes, larger boiler flues, recessing soil fittings or rubber flue sealing grommets!
Our 22mm and 28mm (300mm long) high quality core bits can also be used to minimise making good from blowing the brick face or blowing a rendered wall.*
*compared to drilling holes when using an SDS drill bit on hammer action!
1 – 1/2″ BSP female thread
2 – Spiral and slotted barrel
3 – UK designed high quality diamond tips for UK building materials
Please note: The 22mm & 28mm x 300mm long cores are not suitable for SDS drills due to the low RPM. A mains powered Core drill rated at 850 Watts minimum is suitable for use on standard bricks (not engineering bricks) and standard concrete blocks.
Prevents blowing the brick-face or render wall compared to an SDS drill bit on hammer action.
Prevents blowing the brick-face or render wall compared to an SDS drill bit on hammer action.
Suitable for use with 32mm solvent weld waste pipe elbow.
Suitable for use with 40mm solvent weld waste pipe elbow or when using a pipe snug wall collar.
Suitable for use with insulated condense pipe (32mm waste pipe & 19mm wall thickness insulation as per BS 6798) and for heat pumps to prevent cold bridging (28mm or 35mm copper & 19mm wall thickness insulation).
Suitable for use with boiler flue pipes.
Suitable for use when recessing 110mm soil fittings into a wall (commonly used for a swept branch on a soil stack) or when using a flue snug wall collar.
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). We must receive the photographic evidence within 48hrs of any situation occurring for examination by our technicians, to: [email protected]

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.
