Marcrist CR850 Super Abrasive Diamond Blade

The Marcrist CR850 is a multi material diamond blade designed to handle the full range of materials a busy tradesperson encounters on site. Cast iron, reinforced concrete, steel, granite, armoured glass, fibreglass, composites, MDF, plastic the CR850 is built to cut all of them without needing to stop and swap blades. If you regularly find yourself switching between materials mid-job, this blade removes that problem entirely.

Marcrist has built the CR850 using a combination of natural and synthetic diamonds bonded into a segment profile designed to maintain cutting speed and edge life across hard and abrasive materials alike. The segment geometry is engineered to improve airflow around the blade during cutting, which helps clear swarf and debris while keeping the blade temperature in check. Heat is one of the main reasons diamond blades fail prematurely, so the cooling design directly extends working life.

What Makes the CR850 a Multi Material Diamond Blade Worth Carrying

The CR850 uses Marcrist’s M-segment technology, which is particularly effective when cutting reinforced concrete and other composite materials. The segment design maintains consistent contact with the material rather than glazing over, which is a common failure point with cheaper multi material blades. A glazed segment stops cutting efficiently and makes the operator push harder which puts strain on both the tool and the blade. The CR850 is built to avoid this by staying self-sharpening throughout its working life.

The blade also features an armoured core. In practice, this reduces vibration and dampens the sound level during operation, which matters when you are working in occupied buildings or for extended periods. It also stiffens the blade under lateral load, reducing flex when pushing through dense material.

Materials the CR850 Cuts Reliably

Cast iron, steel, iron and armoured glass are at the harder end of the spectrum where many general-purpose blades struggle or wear quickly. The CR850 handles these alongside softer materials like MDF, PVC and rubber which makes it the practical choice for plumbers, electricians, maintenance engineers and general builders who cannot afford to carry a different blade for every material. Marcrist themselves are confident enough in this blade’s capability to back it with a money-back guarantee if you find a material it will not cut. That is either a bold marketing claim or a genuinely capable blade. Looking at the construction and the materials listed, it is the latter.

Available in 115mm, 125mm, 230mm, 300mm and 350mm diameters to suit angle grinders and cut-off saws across the range. The bore sizes cover the most common fittings including 20mm, 22mm and 25.4mm arbors, so compatibility with standard machines is well covered.

For any trade where stopping to find the right blade costs more time than the blade itself costs money, the Marcrist CR850 multi material diamond blade is a straightforward investment.
