Segmented vs Turbo vs Continuous-Rim Diamond Blades
Use a segmented blade for fast, aggressive general cutting; a turbo blade when you want speed plus a smoother edge; and a continuous-rim blade for chip-free finish cuts in tile and stone (run wet). The rim design controls how fast you cut and how clean the edge is.
Segmented blades
Segmented rims have gaps (gullets) between segments for airflow, cooling, and debris clearance. They’re the fastest, most aggressive choice and the jobsite standard for concrete, asphalt, and masonry. The trade-off is a rougher edge — fine for structural cuts, demolition, and trenching.
Turbo blades
Turbo rims have a continuous edge with a serrated or vented design. They cut nearly as fast as segmented but leave a smoother edge with less chipping — a good all-rounder for masonry, block, and general concrete where finish matters a bit more.
Continuous-rim blades
Continuous rims have a smooth, gap-free edge and are run wet. They cut slower but deliver chip-free, finished edges — the right choice for tile, porcelain, granite, and marble where the cut is visible.
How to choose
Speed and structural cuts → segmented. Balance of speed and finish → turbo. Clean, finished, visible cuts → continuous rim. Shop by material and rim type or call our team at (701) 922-1526.
Why do blades have gullets at all?
The gaps between segments are not there to save material. They are doing three jobs, and every rim design is a trade-off between them.
Clearing debris. Material removed from the kerf has to go somewhere. In concrete and block that means a substantial volume of spoil, and without gullets it packs into the cut and the blade stops working.
Cooling. Gullets let air move across the segment faces. On a dry-cut blade this is most of the cooling it gets, which is precisely why a continuous rim cannot be run dry.
Allowing expansion. A steel core heats and grows. Gullets give it somewhere to go rather than distorting the disc.
Against those benefits, every gullet is an interruption in the cutting edge. Each time a segment leaves the cut and the next enters, the material at the exit face is momentarily unsupported. That is the entire reason chipping happens, and the entire reason continuous rims exist.
How do you trade finish quality against cutting speed?
Rim choice is really a single question: does the cut face end up visible?
If it does not, take the fastest rim the material allows. A structural slab cut, a trench boundary, a demolition opening, a footing — nobody inspects the arris, so a segmented rim clearing debris efficiently is the right answer and anything else is slower for no gain.
If it does, work back from the finish. Porcelain and polished stone need a continuous rim run wet, and you accept a slower cut as the price. Pavers, face brick and exposed block sit in between, which is exactly the gap a turbo rim fills — serrated enough to clear debris and cut dry, unbroken enough to avoid top-face chipping.
A practical ranking
Fastest to cleanest: segmented, then turbo, then continuous. Roughest to smoothest edge runs in the same order reversed. There is no rim that is fast and clean, and a supplier telling you otherwise is selling rather than advising.
Frequently Asked Questions
What’s the difference between segmented, turbo and continuous-rim blades?
Segmented blades cut fastest with a rougher edge and are used dry on concrete and masonry. Turbo blades cut fast with a smoother edge and better cooling. Continuous-rim blades cut slowest but cleanest and are used wet on tile and stone.
Which blade gives the cleanest cut?
A continuous-rim blade used wet gives the cleanest, chip-free edge, which is why it’s preferred for tile, porcelain and natural stone.
Can I use a segmented blade on tile?
It’s not recommended. The gaps between segments chip tile edges. Use a continuous-rim or turbo blade for tile and porcelain instead.
Which blade is the fastest?
A segmented blade removes material the fastest, making it the best choice for concrete and masonry where cutting speed matters more than edge finish.
Why do diamond blades have gaps between the segments?
The gullets clear spoil from the kerf, let air cool the segments, and give the steel core room to expand as it heats. The cost is that every gullet interrupts the cutting edge, which is what causes chipping on the exit face.
Which rim cuts fastest?
Segmented, followed by turbo, then continuous. Edge quality runs in exactly the opposite order. No rim design is both fastest and cleanest, so choose based on whether the cut face will be visible in the finished work.
When should I pick a turbo rim?
When you need a reasonably clean edge but still want to cut dry and cut quickly. Pavers, face brick and exposed block are the classic cases. The serrated profile clears enough debris to run dry while the unbroken edge avoids the top-face chipping a segmented rim leaves.
