Turbo or segmented diamond blade

Updated: 21 October 2026

You are standing in front of two 115 mm discs that look similar in the photo, and the way to choose a turbo or segmented diamond blade is the edge you need to keep. A turbo or mesh rim is the one for glazed ceramic and porcelain. A segmented rim is the one for brick, block, paving and concrete. One disc asked to do both is how a bathroom tile gets chipped. The [diamond cutting disc comparison](/hub/sanders/diamond-cutting-disc) lists the twelve amazon.co.uk products, at £6.98 to £19.90 on 19 October 2026. We did not run a lab test.

What turbo and segmented mean on a 115 mm disc

A turbo rim is a continuous, often wavy, cutting edge. The diamonds stay in contact with the glaze, and the wave gives the dust somewhere to go. A mesh turbo is that idea with a finer web. EZARC, Anesty and RDXMAX are the 115 mm turbo or mesh discs here, at about 1.2 mm. They are the porcelain compromise, not a trade continuous rim. A segmented rim is toothed blocks with slots that clear heat on masonry and nick glaze. Tech Traders is that disc at 1.9 mm, £9.79 for three, 4.5 from 3,103 reviews. worksky is £9.99 for three, 1.8 mm, 4.6 from 22 reviews. ATS Diamond Tools maps turbo and continuous rims to porcelain and glazed tile, and segmented rims to harder masonry. Bore and speed sit on the diamond cutting disc buying guide.

When a turbo or mesh rim wins

Choose turbo or mesh when the cut is on glazed ceramic or porcelain and someone will see the edge. You still feed slowly, and UK reviews still include chips. EZARC at £17.97 carries both praise and chip failures. RDXMAX at £15.99 has one report of the disc spinning in the flanges. Bosch at £6.98 is the ceramic disc, and the listing does not call it a turbo. Move to EZARC, RDXMAX or Anesty when the tile is porcelain. A mesh rim loads on a long dusty block. The porcelain edge itself is on the diamond cutting disc for porcelain page.

When a segmented rim wins

Choose segmented when the material is brick, block, paving or a concrete cill, and the edge does not have a glaze you need to keep. The slots let air through, so a segmented disc stays happier on a long masonry run than a closed turbo rim. Tech Traders has the review base: three 115 mm discs, 13,000 rpm stated, bore printed as 22.2 mm. worksky is on 22 reviews, so mount Tech Traders first. Treat the dust as silica. CIS36 still asks for water or extraction, and RPE at APF 20 where the task needs it.

Pairings that spoil the cut

The common swap is a segmented disc on a glazed porcelain edge. It will cut the tile, and it will chip the face. A turbo disc on a long concrete cut loads, and the dust is still silica. Electroplated and vacuum-brazed bonds are not a third rim. SANLEETEK screws onto an M14 thread. RTDHO is 2.4 from eight reviews and the layer vanished quickly. LEKOMESH has no UK review text. WojBear has no review line. Vearter is a 76 mm mandrel, and DT-DIATOOL is 180 mm. If the day includes porcelain and a concrete cill, buy two rims.

Common questions

Which rim for porcelain bathroom tiles?
A turbo or mesh rim. EZARC, RDXMAX and Anesty are the 115 mm discs in that class here. A segmented rim is more likely to chip the glaze. Bosch is the inexpensive ceramic disc, and the listing does not describe it as a mesh turbo. You still feed slowly, and a show mitre may need a wet saw.
Which rim for paving slabs?
A segmented rim. Tech Traders at £9.79 for three, with 4.5 from 3,103 reviews, is the masonry pack with the review base. worksky is the other segmented three-pack, on 22 reviews. A turbo disc is the wrong tool once the run is long and dusty. Treat the dust as silica, with extraction or water and RPE at APF 20 where CIS36 says the task needs it.
Can one disc do both tile and block?
Not well, in this set. A segmented disc chips glaze. A turbo or mesh disc loads on a long masonry cut. If you have both jobs on the same day, buy one rim for the tile edge and one for the block. There is no hybrid in these twelve listings that the UK reviews support for both.
What is mesh turbo compared with a plain turbo?
Mesh turbo is a finer web in the same family: a near-continuous edge with paths for dust, aimed at porcelain. Plain turbo is the wavier continuous rim. EZARC, Anesty and RDXMAX are sold in that mesh or turbo band at about 1.2 mm. The split to make first is still turbo-or-mesh against segmented. Segmented chips glaze. Turbo and mesh load up on a long block run.
Is the Bosch ceramic disc a turbo?
The listing does not say so. Bosch (B004O4KUKS) is a single 115 mm ceramic disc at £6.98, 1.6 mm, 4.6 from 5,979 reviews. Use it for glazed ceramic. For porcelain, move to a disc described as turbo or mesh, such as EZARC or RDXMAX. Chips still appear in those reviews.
Where does a vacuum-brazed disc fit?
It is a way of holding the diamonds, often with a thin kerf, not a winner of the turbo-versus-segmented choice. RTDHO, LEKOMESH and WojBear sit in that group here. RTDHO’s eight UK reviews, at 2.4, say the layer wore through quickly. LEKOMESH has no UK review text. WojBear has no review line. A 1 mm claim does not replace a masonry segment on paving.
