The Dart Red Ten BMI-10 PRO Multi-Material Diamond Blade is a professional-grade segmented diamond blade designed for tradespeople who need one reliable blade across several common materials. Whether you’re cutting block paving, engineering brick, concrete, or the occasional steel section, the BMI-10 PRO handles it without needing a blade change mid-job. It fits standard angle grinders and cut-off saws with a 22mm or 20mm bore, across a size range from 115mm up to 350mm.
The turbo rim design on the BMI-10 PRO gives it a noticeably smoother cut compared to a standard segmented blade. The serrated edge of a turbo rim draws material away from the cut as the blade runs, reducing drag and keeping the cut line cleaner. For block paving work especially, that matters a rough cut on a visible edge means extra dressing time, and nobody’s billing for that.
What Sets the Dart BMI-10 PRO Diamond Blade Apart
The reinforced steel centre is one of the more practical design features on this blade. It stiffens the plate under load, which reduces the harmonic vibration that causes that familiar high-pitched whine on thinner blades. On a long day of cutting, a quieter blade is a better blade, and it’s not just about comfort reduced vibration also means a more controlled cut.
The BMI-10 PRO carries BMI-10 diamond bond specification, which balances cutting speed with segment longevity. The diamond concentration and bond hardness are matched to general construction materials rather than being optimised for one specific substrate. That’s what makes it a genuine multi-material blade rather than a compromise it’s designed for this range of use from the outset.
Steel Cutting with the BMI-10 PRO
The blade will cut steel, but this needs some context. Light, occasional cuts through rebar, steel angle or conduit are within its capability. Using it as a dedicated metal cutting blade will burn through the segments far faster than the application warrants. Keep a dedicated metal blade for regular steel work, and treat the steel-cutting ability of the BMI-10 PRO as a useful backup rather than a primary function.
Available in six sizes from 115mm to 350mm, the Dart Red Ten BMI-10 PRO covers everything from a small 4.5-inch grinder up to a 14-inch floor saw or cut-off machine. The 350mm variants are available in both 20mm and 25mm bore fittings to suit different machine spindle sizes worth checking before ordering if you’re running the larger diameter. Sold individually, so you can pick up exactly the size you need without buying a pack you won’t use.
Pro Tip: When cutting hard engineering brick or dense concrete with the BMI-10 PRO, let the blade do the work at a steady feed rate rather than forcing it through quickly, as pushing too hard overheats the segments and shortens blade life significantly.
The Dart BMI-10 PRO diamond blade is used across groundworks, landscaping, general building, and civils work where a range of materials needs cutting in a single session. It suits block paving installation and repair, brick cutting on new build and renovation work, concrete kerb laying, and general masonry cutting on site. On smaller sizes, it works well on an angle grinder for precise cuts and trimming work. On the larger 300mm and 350mm sizes, it suits cut-off saws and floor saws for longer runs through paving or concrete slabs. It also handles the occasional light steel cut when needed, making it a practical daily-carry blade for groundworkers and bricklayers.

Not suitable for: Not suitable for regular or heavy-duty steel cutting a dedicated metal blade should be used for frequent steel work. Not recommended for wet-cut applications or use on brittle materials such as ceramic tiles or glass.
Fit the BMI-10 PRO onto a compatible angle grinder or cut-off saw, ensuring the bore matches the machine spindle and the blade is secured with the correct flange and nut. Always check the blade's maximum RPM rating is not exceeded by the machine speed before use.
Mark the cut line clearly before starting. Begin the cut at a steady pace without forcing the blade into the material. On harder materials such as engineering brick or dense concrete, allow the blade to work at its natural feed rate. Forcing the blade accelerates segment wear and can cause overheating. For longer cuts on paving or concrete, keep the cut line straight and avoid lateral pressure on the blade.
Check that the blade bore matches the machine spindle size before fitting
Confirm the machine's RPM does not exceed the blade's maximum rated speed
Fit the blade with the correct flange and secure the nut firmly using the correct spanner
Mark the cut line clearly on the material before starting
Start the cut at one end of the line with the machine running at full speed before contact
Maintain a steady feed rate without forcing the blade through the material
Avoid lateral or sideways pressure on the blade during the cut
Allow the blade to cool between extended cutting sessions to prevent overheating
Can the Dart BMI-10 PRO blade cut steel?
Yes, but only for occasional and light steel cutting such as rebar or steel angle. It is not designed as a dedicated metal cutting blade and using it heavily on steel will significantly reduce segment life. Keep a separate metal blade for regular steel work.
What sizes are available and which machines do they fit?
The BMI-10 PRO is available in 115mm, 125mm, 230mm, 300mm, 350mm x 20mm, and 350mm x 25mm. The 115mm and 125mm sizes suit standard angle grinders. The larger sizes suit cut-off saws and floor saws. Check your machine's spindle bore before ordering, particularly for the 350mm variants which are available in both 20mm and 25mm fittings.
Why does the BMI-10 PRO have a reinforced steel centre?
The reinforced steel centre stiffens the blade plate under load, which reduces vibration and the high-pitched noise common with thinner blades. It also contributes to a more stable cut, particularly on larger diameter sizes running at higher speeds.
The Dart BMI-10 PRO uses a BMI-10 diamond bond specification, with diamond segments matched for general construction materials including brick, block, concrete and light steel. The turbo rim profile aids debris clearance and produces a cleaner cut face compared to a standard segmented edge. The steel plate incorporates a reinforced centre section to reduce harmonic vibration during use. Available bore sizes are 22mm, 20mm and 25mm depending on blade diameter.
