    Which size for a waste pipe?

    A 40mm solvent-weld waste pipe measures about 43mm outside, so a 52mm core leaves roughly 4.5mm each side for sealing. A 32mm waste pipe measures about 36mm outside, and a 48mm core gives it a neat fit with room to seal.

    Dry or wet core?

    Dry cores (DCU350, DCU550, DCU750X, PC850 and CCU850X) cut without water, so with dust extraction there is no slurry to clean up indoors. The PC850 also runs from a percussion drill. Wet cores (the WCU and WF850X ranges) need a water feed, are the usual choice for heavily reinforced concrete and are often used on a drilling rig. The CCW850X is a semi-wet core that needs only a little water.

    Other popular sizes: 38-42mm, 107mm, 117mm, 127mm and 152mm. Or browse all diamond core drill bits and core drill sets.
