Marcrist CCW850X Hand Held Wet Diamond Core

The Marcrist CCW850X wet diamond core is one of those bits that earns its place on the van. Designed primarily for wet drilling, it cuts through hard building materials with the kind of consistency that saves you time and money on a busy site. Whether you’re coring through standard concrete, engineering brick, granite, or even steel-reinforced concrete, the CCW850X is built to keep cutting when cheaper alternatives have given up. Available in a wide range of diameters from 38mm right up to 200mm, there’s a size here for pretty much every job you’ll come across.

Marcrist have a long-standing reputation in the diamond tooling market, and the CCW850X reflects that. The segments are guaranteed not to detach during use, which is more than a minor detail — a loose segment mid-cut can damage your core drill, wreck the workpiece, and cause a genuine safety issue. That guarantee matters.

What the Marcrist CCW850X Wet Diamond Core Will Drill

The material list for this core is genuinely broad. Typical building brick and block, concrete bricks, block paviors, engineering bricks, prefabricated concrete, granite, lintels, natural stone, Kalksandstein, Poroton, refractory clay pipes, concrete pipes, and steel-reinforced concrete are all well within its range. That covers the vast majority of coring work a contractor or installer will encounter on residential and commercial sites.

It’s worth noting that the CCW850X will also drill granite and lightly reinforced concrete dry, which gives you a degree of flexibility when water supply on site is awkward. Wet drilling remains the primary intended use and will extend the life of the core, but having a dry option in the back pocket is useful.

Wet Versus Dry Use

The CCW850X is rated mainly for wet drilling, which is standard practice for cores of this size and hardness range. Water cools the segments, flushes debris out of the cut, and significantly extends the working life of the bit. On harder materials like granite or dense concrete, trying to push a core dry without the right conditions will burn through your investment fast. Use wet wherever you can.

For professional contractors working across building, civils, drainage, or utilities, the marcrist ccw850x wet diamond core covers a huge range of applications in a single, well-made product. At this price point, the segment guarantee and material range make it a straightforward choice.
