Mexco DCX90 Premium Diamond Core – Slotted

The Mexco DCX90 slotted diamond core is one of those tools that earns its keep quickly. Designed for dry core drilling, it cuts through soft and medium facing brick, concrete block, breeze block, ligacite block, hard sandstone, coarse sandstone and soft slate without fuss. The slotted barrel design aids debris clearance while drilling, which keeps the core running cooler and helps maintain a cleaner cut. If you have ever watched a blocked core seize up halfway through a wall, you will appreciate why this matters.

Mexco have built a solid reputation in the diamond tooling market, and the DCX90 range reflects that. The high quality diamond segments are bonded to welded steel barrels, giving you a tool that holds up to repeat use rather than one that performs well once and deteriorates. Dry core drilling puts considerable stress on both the segment and the barrel, so construction quality here genuinely affects service life.

Where the Mexco DCX90 Slotted Diamond Core Gets Used

On site, this is the core drill you reach for when putting holes through external walls for soil pipes, gas supplies, cable routes, ventilation ducts, or air source heat pump pipework. It is equally useful in internal block walls where you need a clean, accurate hole rather than the ragged mess a hammer drill leaves behind. The range of available diameters covers the most commonly specified hole sizes on residential and commercial jobs alike.

Available Sizes

The DCX90 slotted range is available from 22mm through to 182mm diameter, with barrel lengths of 165mm or 400mm depending on the size selected. The shorter 165mm barrels suit most standard wall thicknesses. The longer 400mm option handles deeper penetrations, useful when boring through thicker masonry constructions or where you need to core from one side only without breakthrough access. Both connect via standard SDS-plus or core drill adaptor, depending on your setup and the diameter in use.

Speed matters on site, and the DCX90 delivers on that front. The combination of premium diamond segments and the slotted barrel design means faster penetration rates compared to a standard closed barrel core in similar materials. Less time per hole means more holes per shift, which on a large install is worth more than the price difference between a budget core and a quality one. The mexco dcx90 slotted diamond core is the kind of purchase that pays for itself across a few jobs rather than just one.
