Dart Red Ten BMI-10 PRO Multi-Material Diamond Blade

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.
