The OX Spectrum TX10R is a 300mm multi-material turbo diamond blade built for fast, clean cutting through concrete, engineering brick, granite, natural stone, metal and general building materials. Reinforced centre plate, cooling holes, and vibration damping included.
The OX Spectrum TX10R Ultra Premium Turbo Diamond Blade is a 300mm x 20mm multi-material cutting blade designed for tradespeople who need reliable performance across a wide range of construction materials. Whether you are cutting concrete, granite, natural stone, clay products, engineering bricks, or metal, this blade handles the lot without swapping out mid-job. The TX10R sits at the top of the OX Spectrum range, and the difference in build quality over budget blades is noticeable from the first cut.
The turbo segment design is what gives this blade its speed. The segmented rim creates a turbine effect as the blade spins, drawing air through the gullets and cooling the cutting edge during use. This extends segment life and reduces the risk of warping on long cuts. Alongside the turbo geometry, OX has incorporated cooling holes into the blade body to further manage heat, which matters when you are pushing a 300mm blade through hard aggregate or reinforced concrete on a warm day.
The reinforced flange and centre plate are there for a reason. Hard materials push back, and a blade that flexes under load becomes inaccurate quickly. The TX10R is built to stay straight under pressure, which means cleaner cuts and less cleanup work. The semi-silent, vibration-damped design also helps with operator comfort over longer periods of use.
Where the OX Spectrum TX10R Ultra Premium Turbo Diamond Blade Earns Its Keep
This is not a blade you reach for when you have one tricky cut to make in a specific material. The TX10R is designed for the kind of day where the job list includes breeze blocks in the morning, a reclaimed granite step at lunchtime, and a few angle-iron cuts before home time. Multi-material capability means less time rummaging through the van for a different blade.
The 10mm segment height gives the blade a good working life, even on harder materials. That said, segment wear does increase on highly abrasive materials like soft sandstone or old lime-based products, so it is worth factoring that into any estimate where abrasive materials dominate the job.
Cutting Metal with a Diamond Blade
The TX10R is rated for metal cutting, which sets it apart from most standard diamond blades. Rebar, angle iron, and steel fixings can be cut without reaching for an angle grinder or abrasive disc. This is particularly useful on reinforced concrete jobs where the blade encounters steel mid-cut rather than in a planned pass. The blade does not stop and protest, it continues through.
The OX Spectrum TX10R Ultra Premium Turbo Diamond Blade is built to Spectrum safety standards and is suitable for use on angle grinders and cut-off saws with the appropriate 20mm bore fitment. At 300mm, it covers the most common cutting depths required on construction sites without needing specialist equipment to run it.
Pro Tip: When cutting metal with the TX10R, keep the blade moving at a consistent feed rate rather than forcing it or slowing down mid-cut, as stalling generates heat quickly and will shorten segment life noticeably.
The OX Spectrum TX10R is used across construction, groundworks, and general building trades for cutting a wide range of hard materials on site. Common applications include cutting concrete slabs and blocks, granite worktops and natural stone paving, engineering bricks, clay roof tiles, and mixed rubble. It also handles steel and rebar, making it a practical choice on reinforced concrete work where the blade may encounter embedded metal mid-cut.
The 300mm diameter suits cut-off saws and large angle grinders used for general site cutting tasks, kerb laying, drainage channel work, paving, and structural alterations. The multi-material capability makes it a sensible single blade to carry when the day involves more than one material type.

Not suitable for: Wear increases significantly on highly abrasive materials such as soft sandstone or old lime mortar, which will shorten segment life faster than normal use. This blade is not designed for wet-only cutting applications that require a continuous rim wet blade.
Fit the TX10R to a compatible cut-off saw or angle grinder with a 20mm spindle, ensuring the blade guard is properly in place and the machine is rated for 300mm blades. Check the maximum RPM marked on the blade does not exceed your machine's no-load speed before starting.
Allow the blade to reach full running speed before bringing it into contact with the material. Apply steady, consistent forward pressure rather than forcing the cut. Let the blade do the work. Avoid twisting or lateral pressure during the cut, as this puts unnecessary stress on the segment bond and centre plate.
For long cuts or harder materials, allow short pauses to let the blade cool naturally. Do not plunge the blade into water to cool it rapidly, as thermal shock can crack the steel body. Keep the cutting line clear of debris where possible to reduce drag.
Check the blade's maximum RPM rating and confirm it matches or exceeds your machine's no-load speed.
Fit the TX10R to the spindle using the correct flange arrangement for your machine, ensuring the 20mm bore seats properly.
Refit the blade guard and tighten the locking nut to the manufacturer's torque setting.
Mark your cut line clearly on the material before starting.
Start the machine and allow the blade to reach full running speed before making contact with the material.
Begin the cut with light contact, then apply steady, consistent feed pressure along the cut line.
Avoid twisting the blade or applying lateral pressure during the cut.
For extended cuts, pause briefly to allow the blade to cool rather than running continuously under heavy load.
After use, inspect the segments for wear or damage before storing the blade.
Can the OX Spectrum TX10R cut through steel rebar embedded in concrete?
Yes. The TX10R is rated for metal cutting, including steel, which means it will continue cutting if it encounters rebar mid-pass through reinforced concrete. This is one of the reasons it is classed as a multi-material blade rather than a standard concrete blade.
What machines is the 300mm x 20mm bore compatible with?
The 300mm diameter suits cut-off saws, both petrol and electric, and large angle grinders capable of running a 300mm blade. The 20mm bore is a standard spindle size for most cut-off saws in common site use. Always check your machine's spindle size and maximum RPM rating before fitting.
Will the blade wear faster on softer, more abrasive materials like sandstone?
Yes. Softer abrasive materials such as sandstone and lime-based products wear diamond segments faster than harder, denser materials like granite or engineering brick. The 10mm segment height gives a reasonable working life in normal use, but if your job is predominantly soft abrasive stone, expect to replace the blade sooner than you would on a concrete-heavy job.
The OX Spectrum TX10R uses a turbo-segmented diamond blade body with a reinforced steel centre plate and an integrated 20mm bore. The turbo rim geometry increases airflow over the cutting edge during rotation, reducing operating temperature and extending segment bond life. Cooling holes machined into the blade body provide additional thermal management. The blade meets Spectrum safety standards and is vibration-damped to reduce harmonic transfer to the operator during extended cutting. Segment height is 10mm.
