A 300mm premium diamond blade built for cutting sandstone, limestone, asphalt and green concrete. Features 10mm segments and T-segment undercut protection. Designed for 300mm petrol saws with a 20mm bore and max speed of 5,100rpm.
The Force X Premium Diamond Blade for Sandstone and Abrasive Materials is a 300mm blade built specifically for cutting soft, abrasive materials that eat through standard blades fast. Sandstone, limestone, asphalt and green concrete all share one trait: they wear down segments quickly. This blade is engineered to handle that, with a 10mm usable segment height that keeps the blade cutting long after cheaper options have given up.
The seven T-segments are the feature worth paying attention to. On abrasive materials, the blade body itself is at risk from undercut wear, where the material gradually works its way up and damages the steel core beneath the diamond segments. The T-segment design puts protective material in the gaps to stop that happening, extending the working life of the blade considerably. It is a practical piece of engineering that makes a real difference on jobs involving bulk sandstone or asphalt cutting.
Where the Force X 300mm Sandstone Blade Gets Used
This blade is matched to 300mm petrol cut-off saws, which are the standard tool of choice for on-site work away from power. Kerb laying, paving, groundworks and drainage work all involve cutting abrasive materials in conditions where an angle grinder simply is not practical. The 20mm bore is a common fitment across most major petrol saw brands, and the 5,100rpm maximum speed sits within the operating range of typical handheld cut-off saws.
Landscapers and groundworkers will find the most use from this blade. Sandstone paving is notoriously hard on blades, and cutting it accurately requires a blade that tracks consistently without wobbling or losing depth. The Force X diamond blade maintains clean cutting performance across the full segment life rather than fading rapidly after the first hour of use.
Segment Specification and Blade Life
The 10mm segment height gives a useful indicator of working life. On very abrasive materials like asphalt or soft sandstone, expect the segment to wear more quickly than on harder, denser stone. On limestone and harder sandstone varieties, the segment will last considerably longer. Keeping the blade cool by using steady, even cuts rather than forcing the saw through the material will extend life further. Dry cutting is typical with this blade type, so letting the blade spin freely for a few seconds between cuts to shed heat is worth making a habit of.
The Force X Premium Diamond Blade in the 300mm format is a straightforward, well-specified blade for anyone working regularly with abrasive materials on site. The T-segment protection is not a gimmick. On long cutting runs through paving or kerb stones, it is the difference between a blade that lasts the job and one that needs replacing halfway through. At this price point, it offers genuine trade value for groundworkers and landscapers who go through blades regularly.
Pro Tip: When cutting sandstone or asphalt with a petrol saw, lift the blade clear of the cut every 30 seconds or so and let it spin freely for a few moments to cool down, as continuous pressure in abrasive material builds heat that degrades the bond holding the diamond segments far faster than the cutting itself.
The Force X 300mm sandstone and abrasive materials blade is used primarily in groundworks, landscaping and civils, where cutting soft stone and asphalt is a regular part of the job. Sandstone paving slabs, limestone kerbing, freshly laid asphalt and green concrete are all typical materials. The blade is used on 300mm petrol cut-off saws and is best suited to outdoor site conditions where mains power is unavailable.

Seven T-segments for undercut protection
Dry cutting blade
Not suitable for: Not suitable for cutting hard granite, engineering brick or reinforced concrete, where a harder bond blade is required. Not compatible with angle grinders or saws with a spindle other than 20mm bore.
Fit the Force X 300mm blade to a 300mm petrol cut-off saw with a 20mm bore arbour, ensuring the blade is seated correctly and the retaining nut is torqued to the saw manufacturer's specification. Check the arrow on the blade matches the direction of rotation before starting.
Mark your cut line clearly before starting the saw. Lower the blade into the material using steady, consistent forward pressure without forcing the saw. Allow the blade to do the work rather than pushing hard through the material. On very abrasive materials like asphalt, make slightly shallower passes if the saw is labouring. Lift the blade clear of the cut periodically to allow it to cool.
Check the blade is the correct type for your material before fitting
Fit the blade to the 300mm petrol saw with a 20mm bore arbour, ensuring the rotation arrow matches the direction of spin
Torque the retaining nut to the saw manufacturer's specified setting
Mark the cut line clearly on the material before starting
Start the saw and allow it to reach full speed before contacting the material
Lower the blade into the material with steady, even forward pressure without forcing
Lift the blade clear every 30 seconds on long cuts to allow the segments to cool
Allow the saw to return to full speed before continuing each pass
Can I use this blade on a 300mm angle grinder instead of a petrol saw?
No. This blade is rated for 300mm petrol cut-off saws only. Angle grinders operate at significantly higher RPM than the 5,100rpm maximum rating of this blade, which would make use on an angle grinder unsafe. Always match the blade's maximum RPM to your tool's operating speed.
Will this blade cut hard granite or engineering brick?
The Force X sandstone and abrasive materials blade is not designed for hard stone such as granite or dense engineering brick. Those materials require a blade with a harder bond specification. Using this blade on granite will cause rapid and premature segment wear. Choose a blade matched to hard stone or hard general purpose use for those applications.
What does the T-segment design actually do, and does it make a real difference?
On abrasive materials like sandstone and asphalt, the material can undercut the blade body beneath the diamond segments, wearing away the steel core and shortening blade life significantly. The T-segments fill the gaps between the main cutting segments with protective material, shielding the blade body from this type of wear. On longer cutting runs through abrasive stone, this protection makes a measurable difference to how long the blade lasts.
The Force X 300mm sandstone and abrasive materials diamond blade uses a segmented rim construction with 10mm diamond-impregnated segments bonded to a steel core. The seven T-segment configuration provides undercut protection to the blade body during use on high-wear abrasive materials. The 20mm bore and 5,100rpm maximum speed rating are matched to standard 300mm petrol cut-off saw specifications. The blade is rated for dry cutting use.
