How to Choose Diamond Saw Blades for Concrete, Asphalt and Stone: A Guide to Bond Hardness
Most early blade failures are selection errors, not defects: match bond hardness to the material first, then confirm rim type, cutting depth, and rated speed.
Selection guidance depends on material, machine, and working conditions. Confirm RPM, feed, and cooling against tool markings and machine instructions, then trial the target material.

Start with the answer
Most premature diamond blade failures are selection problems, not quality problems. A blade keeps cutting because its metal bond wears away at a controlled rate and keeps exposing fresh diamond. Match the bond wear rate to the material first, then confirm rim type, cutting depth, and rated speed for your saw.
The one rule
Soft, abrasive materials such as asphalt, green concrete, and abrasive block grind the bond down quickly, so they need a hard bond that resists wear; with a soft bond the segments can disappear within a single job. Hard, dense materials such as granite, hard cured concrete, and reinforced concrete barely wear the bond, so they need a soft bond that releases dull diamonds quickly; with a hard bond the blade glazes over, stops cutting, and only polishes the surface.
Rim type
Segmented rims cut fastest and their gullets clear debris, which makes them the standard choice for concrete and masonry, at the cost of a rougher edge. Turbo rims use a serrated edge to balance speed and finish and suit stone and pavers. Continuous rims give the cleanest, chip-resistant edge for tile and marble but cut more slowly and are almost always used wet.
Diameter and cutting depth
As a rule of thumb, maximum cutting depth is roughly one third of the blade diameter, less a margin for the arbor and flanges: about 32 mm for a 115 mm blade, 65 mm for 180 mm, 95 mm for 300 mm, 120 mm for 350 mm, and 195 mm for 500 mm. If you regularly cut 100 mm units with a 250 mm blade, plan to cut from both sides or step up a diameter. Always confirm the depth against the saw manufacturer specification.
Safety checks
For the European market, look for blades marked as conforming to EN 13236, the safety standard for superabrasive products. Never exceed the maximum RPM printed on the blade, and match the blade to the saw operating speed, not only to its arbor size. Use laser-welded segments for dry cutting, because dry cutting runs much hotter; brazed segments are generally for wet use only. Keep a steady feed pressure: forcing the blade overheats the segments and can warp the steel core.
Before you order
State your material first and ask the supplier which bond they recommend for it, instead of choosing by diameter and price alone. Confirm the wet/dry rating, segment height, and arbor size against your saw, and check the blade maximum RPM against the machine operating speed. For EU imports, ask for the EN 13236 conformity marking and the documentation behind it. Trial one blade on your actual material before committing to a batch: cutting behaviour varies with aggregate hardness even within a single material name such as concrete.
Material and Design Checkpoints
| Material you cut | Bond to choose | Rim type | Wet or dry |
|---|---|---|---|
| Asphalt | Hard | Segmented | Dry or wet |
| Green concrete, abrasive block | Hard | Segmented | Wet preferred |
| Medium concrete, brick, pavers | Medium | Segmented or turbo | Dry or wet |
| Hard cured / reinforced concrete | Soft to medium | Segmented | Wet preferred |
| Granite, hard natural stone | Soft | Segmented or turbo | Wet |
| Porcelain tile, marble | Medium to soft | Continuous rim or thin turbo | Wet (dry only if rated) |
