Clipacore XPRESSCUT PRO is an industry first, 23-piece dry core set, delivering faster cutting results for the 21st century trade professional.
The spiral and slotted barrels help remove debris and increases air flow to the cutting edge, while the diamonds and UK developed metal bond system provides trouble free cutting.


The XPRESSCUT 42mm / 52mm / 65mm / 117mm / 127mm premier diamond core bits are suitable for most UK building materials as listed below:  

A – 117mm core bit and quick release core adaptor
B – 127mm core bit and quick release core adaptor
C – 52mm core bit and quick release core adaptor
D – 65mm core bit and quick release core adaptor
E – 42mm core bit and quick release core adaptor
F – 5 x quick release spare clips
G – Waste removal knock out tool
H – 1 x A taper 10mm guide pin and 1 x A taper 10mm drill bit
I – 200mm long HEX extension bar with quick release drill adaptor
J – 200 mm long SDS extension bar with quick release drill adaptor
K – Drift key
L – Compact aluminium carry case with foam lined interior


a) They should not be used to drill through site cast concrete, hard brick such as engineering brick or hard stone.


b) 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.


c) Whenever possible use an 850-watt (min) rotary drill fitted with slipping clutch and variable speed control.


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


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


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


g) Reduce pressure if the bit starts to vibrate.


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


i) Do not – Force the core, let it do the work, this will prolong its life and reduce the chance of failure.


j) The A taper pin and drill bit must be hammered in tight to prevent coming out during use.


k) Always use a standard 10mm sds drill bit prior to using the guide pin (supplied) if the A taper drill bit (supplied) is not used.


l) Percussion mode is not suitable for these core bits.


m) The detachable SDS fitting connected to the extension bar is designed to break and be replaced to protect the SDS drill clutch from damages.
Whist we provide an SDS extension bar within the kit, we strongly urge using a core drill with a higher clutch limit and higher torque, using the HEX extension bar provided as this can sustain common situations such as the core bit jamming whilst drilling.


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]

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.
