Segmented vs turbo diamond blade on a 230 mm disc
Updated: 21 October 2026
You need a masonry disc for a 9 inch grinder, and the thumbnail does not say whether a segmented vs turbo diamond blade will change the cut. Most discs here are plain segmented, two are turbo or turbo-segmented, and none is a continuous rim for porcelain. Choose for edge risk and segment height, then check whether a UK review file describes that rim. The rows are on the [230mm diamond cutting disc comparison](/hub/sanders/230mm-diamond-cutting-disc). The Products Compared editorial team compared the saved listings on 19 October 2026. We did not time a cut. A qualifying purchase can earn a commission at no extra cost to you.

What a segmented rim is doing
A segmented rim is a steel core with diamond sections and gaps between them. The gaps clear dust and shed heat. Norton’s UK note treats segments as the masonry edge and a continuous rim as the tile edge. That is why a segmented disc is the default here for concrete, brick, block, and slabs. Bore and height are on the 230mm diamond cutting disc buying guide.
The segmented rows run from TopsTools at £8.99 and S&R at £15.49 with a stated 10 mm height, through PRODIAMANT at £16.70 with a stated 7 mm segment, to Bosch EXPERT at £84.43. Tech Traders at £9.99 leaves the rim cell blank. The EXPERT scope line is 230 x 22.23 x 2.4 x 15 mm. That 15 mm is segment height on a segmented disc, not a turbo rim.
What turbo and turbo-segmented add
A turbo or turbo-segmented rim keeps an aggressive edge and a serrated face on the segments. The OX XLC15-230/22 at £15.24 names wide gullets and holes for cooling. It is turbo-segmented, bore 22.23 mm, with a 15 mm segment in the bullets, and the amazon.co.uk file has no customer-review line.
Bosch part 2608602397 is the other turbo, at £26.99, with 4.6 from 715 reviews. Bosch Professional UK lists it as 230 mm, bore 22.23 mm, width 2.5 mm, segment 10 mm. The Amazon title says small grinders. Fit it only on a 230 mm machine. The file we read held two reviews. The listing weight of 110 g is a data gap. Nothing here is a timed comparison, so faster stays a description of the rim.
When segmented wins, and when turbo wins
Choose a segmented rim when the edge will be seen, on ordinary brick, block, or patio slab. S&R at 4.6 from 6,401 and PRODIAMANT at 4.5 from 7,076 are the volume picks. TopsTools at £8.99 is the short job. Rim type does not cancel a cheap bond. Named picks are on the best 230mm diamond cutting disc page.
Choose turbo when you accept a rougher arris, typically on concrete where a chipped corner can sit in a joint. If you need a turbo rim and a deep UK review sample, this set does not contain that disc. Paying £84.43 for the EXPERT buys a 15 mm segmented edge and 4.8 from 486 reviews, not a turbo. Dust control does not change with the rim. HSE’s limit for respirable crystalline silica is 0.1 mg/m³ over 8 hours. Gullets do not replace water, extraction, or respiratory protection.
What this set does not sell
There is no continuous-rim porcelain blade among the twelve ASINs. Norton describes that rim for tile, where segments would chip the glaze. DeWalt’s materials field mentions ceramic and marble while the bullets say concrete and masonry, so trust the bullets for brick and slab. A reinforced-concrete bullet does not make a turbo rim a steel wheel. Only Blue Spot and Tech Traders print a speed, 6,600 rpm and 6,650 rpm. If the rim cracks, the disc is finished.
Common questions
Is a turbo diamond blade always faster?
The rim is built to cut more aggressively, which is why listings call it turbo. This comparison has no timed cuts of turbo against segmented on the same material, so there is no minute-saving to quote. On a short patio the difference may matter less than a chipped corner. On a long concrete cut, the aggressive edge is the reason to pay for it, once the dust controls are already in place.
Will a turbo rim chip slabs more?
It can, because the edge is more aggressive than a plain segmented rim, and a visible Indian sandstone arris shows that chip. Nothing here is a lab score for breakout. The OX turbo has no UK reviews in the file, so chipping on that disc is unreported. For a corner you will see, stay with a segmented disc that has a large review sample, and use a relief cut.
What is turbo-segmented versus plain segmented?
A plain segmented rim has diamond sections separated by gullets. Turbo-segmented keeps those gaps and puts a serrated face on the segments. In this set the OX XLC15-230/22 is the turbo-segmented disc, with a stated 15 mm segment. Bosch part 2608602397 is listed by Bosch UK as a turbo disc with a 10 mm segment. Bosch EXPERT, also 15 mm, is segmented, not turbo.
Which discs in this table are turbo?
Two. The OX XLC15-230/22 at £15.24 is turbo-segmented, 15 mm, with no review line. Bosch 2608602397 at £26.99 is the turbo Bosch UK specs as 230 mm, 22.23 mm bore, 2.5 mm wide, and 10 mm segment. The Amazon title that says small grinders does not change that diameter. Every other disc is segmented or, on Tech Traders, unmarked for rim type.
Can I swap rim type halfway through a job?
You can, on the same 230 mm grinder, if the bore is 22.23 mm and you stop, unplug, and check the arrow and the guard. Do it at the start of a new cut. Stated widths are not identical: Tech Traders prints 2.2 mm, and Bosch UK prints 2.5 mm on the turbo. A wider disc in a narrower kerf can bind. A 15 mm segment height is not a wider kerf. The OX field that reads 15 mm is the segment height repeated.
