Marcrist HW850 Super Slim Wood Cutting Blade 115mm/125mm

The Marcrist HW850 Super Slim Wood Cutting Blade is a vacuum brazed diamond blade designed specifically for cutting wood, laminate, and wood-based sheet materials with an angle grinder. If you’ve ever tried to cut timber with a standard abrasive disc and ended up with a scorched edge, a cloud of dust and a blade that lasted about four minutes, this is the product that puts that experience firmly in the past. As a dedicated wood cutting blade, the HW850 delivers a clean, fast cut with noticeably less waste material and far less mess than conventional methods.

The blade’s super slim profile is central to how it performs. A thinner kerf means less material removed with each pass, which reduces the effort and power required to push through the cut. On a corded machine that might seem like a minor point, but on a cordless grinder it makes a genuine difference to how long your battery lasts and how the tool handles through a full day’s work. The HW850 was clearly designed with cordless use in mind, and it shows.

What Makes the Marcrist HW850 Wood Cutting Blade Different

Marcrist has built the HW850 around three key features: a vacuum brazed cutting segment, an engineered core, and self-cooling technology. Vacuum brazing bonds the cutting material directly to the steel core under controlled heat and vacuum conditions, which produces a stronger and more consistent bond than standard sintered or silver-soldered alternatives. The result is a blade that holds its performance throughout its working life rather than dropping off sharply after the first few uses.

The engineered core is shaped to reduce vibration and flex during the cut. This matters when you’re pushing through hardwood, chipboard, or multi-layer laminate flooring, where an unstable blade can wander, bind, or cause chipping on the face side of the material. The self-cooling design draws air across the blade body during use, which helps manage heat build-up and extends the working life of the blade.

Cut Quality and Dust

The HW850 produces a notably cleaner cut than a standard disc, and the dust output is considerably lower. This is partly a result of the slim kerf, and partly due to the way the diamond segments remove material rather than abrading it. For installers working on finished flooring, fitted furniture, or anything where the cut edge will be visible, the finish quality from the HW850 is a significant advantage over grinding down an abrasive wheel.

Available in 115mm and 125mm diameters, both with a 22mm bore to suit standard angle grinder spindles. Whether you’re trimming laminate flooring, cutting hardwood sections, or working through engineered board on site, the Marcrist HW850 is a wood cutting blade that earns its place in the kit bag rather than just sitting there looking expensive.
