MEXCO GPX90 General Purpose Diamond Blade – 450mm

The Mexco GPX90 General Purpose Diamond Blade in 450mm is a reliable cutting blade designed for floorsaws and large cut-off saws working through non-abrasive construction materials. Concrete, engineering brick, kerb stones, block paving, and natural stone the GPX90 handles the kind of materials that turn up daily on UK construction sites without demanding constant blade changes or fussing over material-specific specs.

General purpose blades get a bad reputation in some quarters, usually from people who’ve used cheap ones. The GPX90 is not a budget compromise. Mexco engineer the GPX90 segment specifically for the mix of hard and moderately hard materials found in mainstream UK groundwork and civils. The diamond bond is tuned for non-abrasive materials, which keeps the segments cutting cleanly rather than glazing over or wearing unevenly on tougher cuts.

Where the Mexco GPX90 Diamond Blade Earns Its Keep

At 450mm, this blade is sized for floorsaws the type of machine used for road repairs, utility trenching, concrete floor cutting, and pavement reinstatement. These are jobs where you need consistent depth and a clean kerf, and where stopping mid-cut to swap blades is not an option. The GPX90 is built to stay in the machine and keep working through the shift.

The blade suits contractors working across concrete slabs, kerbing, flags, and block paving where the material density stays within the non-abrasive range. It performs well in conditions where a specialist blade might be overkill and a cheap blade would give up halfway through the job. For general civils and groundworks teams who cut a range of materials rather than one specific product all day, the GPX90 offers a sensible middle ground.

Segment Design and Cutting Characteristics

The GPX90 uses a segmented rim profile, which allows debris to clear efficiently during the cut and helps manage heat build-up in longer cutting runs. The segment geometry is designed to maintain consistent cutting speed across varying material hardness, which matters when you are cutting through a slab that transitions from dense aggregate to softer mortar beds. Mexco’s manufacturing tolerances keep the blade running true and reduce vibration through the machine, which extends both blade life and machine wear.

Mexco have been producing diamond tooling for the UK market for decades, and the GPX90 reflects that experience. The blade is not designed to be the fastest cutter in a single material it is designed to perform acceptably well across a wide range of jobs without needing the operator to stop and think about whether the blade is matched to the material. On a busy civils site, that kind of practical reliability is worth more than peak performance in a lab test.

The 450mm GPX90 is stocked for professional contractors who need a dependable floorsaw blade that gets on with the work. If your floorsaw runs regular general construction cuts and you want a blade that won’t let you down mid-trench, the GPX90 is a straightforward choice.
