The Mexco general purpose diamond blade GPX10-8 is built for contractors who need a reliable cutting blade without spending a fortune every time a disc wears out. It sits in the GPX range, which Mexco developed specifically around the reality of site work — where you rarely know exactly what the next cut will be through. One minute it’s a concrete kerb, the next it’s hard limestone or a reinforced slab. This blade handles that without complaint.
The 8mm segment height gives you a decent working life before the blade reaches the end of its useful cutting depth. Mexco use a high diamond concentration in the segment matrix, which means the blade keeps cutting cleanly through dense non-abrasive materials rather than glazing over and slowing you down. The conventional keyhole gullet helps clear debris from the cut and keeps things running at a consistent speed — which matters more than people realise when you’re working through hard aggregate.
Where the Mexco GPX10-8 Gets Used on Site
This is the sort of blade that earns its place in a van without much fuss. It’s a natural fit for groundworkers cutting concrete paviours, block layers trimming hard engineering bricks, or anyone setting out foundations through reinforced concrete slabs. Hard limestone, concrete lintels, dense aggregate blocks — all within its range. It’s not designed for soft or highly abrasive materials, but for the core non-abrasive masonry work that makes up most of what’s cut on a typical construction site, it does the job consistently.
Available in 230mm, 300mm x 20mm, 350mm x 20mm and 350mm x 25mm, so it covers everything from a 9-inch angle grinder up to a floor saw or wall chaser. Check your machine’s bore size before ordering — it’s one of those things that feels obvious until you’re standing on site with the wrong blade.
The GPX10-8 is firmly in the budget-conscious end of the Mexco range, which is the point. When you’re burning through blades on a big concreting job or a long run of paving, the price per cut matters. You get a well-made blade at a price that doesn’t sting every time you reach for a new one. Mexco know their blades, and even at this price point, the GPX10-8 reflects that.
Pro Tip: If your blade starts to slow or feels like it is skating across the surface rather than cutting, try making a few passes through a softer abrasive material like a breeze block — this dresses the segment and re-exposes the diamond, restoring cutting speed without needing a new blade.
The Mexco GPX10-8 general purpose diamond blade is used across groundworks, civils and general building trades for cutting non-abrasive masonry materials. Typical jobs include trimming concrete paviours, cutting reinforced concrete slabs, sizing hard limestone flags, and cutting through dense aggregate blocks. It suits angle grinders, cut-off saws and floor saws depending on the size selected. It is a dependable workhorse for day-to-day masonry cutting on new build sites, civils contracts and landscaping projects.

Not suitable for: Not suitable for cutting soft or highly abrasive materials such as sandstone, roof tiles, or asphalt. These materials require a blade specifically formulated for abrasive or siliceous cutting and will wear this blade down rapidly.
Fit the blade to a compatible machine, ensuring the bore size matches and the blade is rated for the machine's maximum RPM. Always check the arrow on the blade matches the direction of rotation on your machine before starting.
Use a steady, controlled feed rate through the material. Forcing the blade through hard concrete generates excess heat and reduces segment life. For reinforced concrete, let the blade do the work rather than pushing hard. If cutting dry, keep passes short and allow the blade to cool between cuts where possible. Wet cutting will always extend blade life on harder materials.
Check the blade size and bore match your machine before fitting
Confirm the blade's maximum RPM rating meets or exceeds your machine speed
Fit the blade with the directional arrow matching the machine's rotation direction
Secure the blade correctly using the correct flange and retaining nut
Start the machine and allow it to reach full speed before beginning the cut
Feed at a steady, controlled rate without forcing the blade through the material
For dry cutting, take shorter passes and allow the blade to cool between cuts
If cut speed drops noticeably, dress the segment with a few passes on a breeze block
What materials can the Mexco GPX10-8 cut through?
It is designed for non-abrasive building materials including reinforced concrete, hard limestone, concrete paviours and dense aggregate blocks. It is not the right choice for soft or highly abrasive materials like sandstone or asphalt, which will wear the segments down far quicker than intended.
Which size should I order for my angle grinder or cut-off saw?
The 230mm size suits a standard 9-inch angle grinder. The 300mm and 350mm sizes are intended for cut-off saws and floor saws. Check the bore size your machine requires — the 350mm blade is available in both 20mm and 25mm bore options, so match that to your machine's spindle before ordering.
The GPX10-8 uses a sintered diamond segment bonded to a steel core, with segment dimensions of 8mm height. The conventional keyhole gullet design assists debris clearance from the cutting path and helps maintain cutting speed through dense material. Mexco specify a high diamond concentration in the segment matrix for this blade, which improves performance and longevity when cutting harder non-abrasive masonry compared to lower-concentration budget blades.
