Diamond Saw Blade Selection — Quick Reference
Diamond saw blades cut hard + abrasive materials that destroy toothed blades — tile + ceramic + glass + masonry + concrete + stone. Cutting action is GRINDING not shearing — diamond particles bonded into metal matrix on rim wear material away. Selection by rim type + bond hardness + material being cut.
| Rim Type | Best For | Cut Characteristics |
|---|---|---|
| Continuous Rim | Tile + porcelain + ceramic + glass — smooth fine cuts | Smoothest finish, slowest cut, MUST be water-cooled |
| Segmented Rim | Concrete + brick + masonry — fast aggressive cuts | Fast, rough finish, can be dry-cut (with limits) |
| Turbo Rim (Hybrid) | General masonry + brick — balance speed + finish | Faster than continuous, smoother than segmented |
| Sintered Diamond Rim | General use — diamond + metal matrix integrated | Common construction blade type |
| Vacuum-Brazed Rim | Premium — diamond bonded to rim via brazing | Longer life, more aggressive cut |
| Electroplated Rim | Fine + delicate work — single layer of diamond | Tile + glass + precision cutting |
| Soft-Bond Blade | Hard materials (cured concrete + porcelain) | Bond wears to expose new diamond |
| Hard-Bond Blade | Soft + abrasive (asphalt + soft sandstone) | Bond holds longer, less premature wear |
| Mesh-Bonded (Diamond Hole Saws + Specials) | Tile + glass holes + ID cutting | Per specialty spec |
Critical: Match BOND hardness to material hardness — soft material + hard bond = bond doesn't wear + diamonds dull (need wear to expose new diamonds). Wet-cutting blades NEVER dry-cut (overheating destroys bond + diamonds in seconds). Match blade MAX RPM to tool. Brand: Austsaw. Companion: Austsaw range, circular saw blades, cut-off discs, abrasives.
Diamond Saw Blades for Tile, Masonry, Concrete & Stone
Diamond saw blades cut through hard, abrasive materials that would destroy a standard toothed blade in minutes. The cutting action is grinding rather than shearing — diamond particles bonded into a metal matrix on the rim wear the material away. This makes diamond blades the only practical option for tile, masonry, concrete, natural stone, fibre cement, terrazzo, ceramic and other mineral-based materials.
Rim types — when to use each
The rim profile of a diamond blade determines its cutting characteristics:
- Continuous rim: An unbroken diamond-impregnated edge. Gives the cleanest cut with minimum chipping — used for ceramic tile, porcelain, glass and where edge finish matters. Slower cut rate than segmented blades.
- Segmented rim: Diamond segments separated by gullets. Maximum cut rate and best heat dissipation — used for hard concrete, brick, paving and demolition. Coarser edge finish than continuous rim.
- Turbo rim: Serrated continuous rim with cooling notches. Balances cut speed and edge quality — versatile general-purpose choice for stone, masonry and brick.
Wet vs dry cutting
Wet cutting uses water to flush debris, cool the blade and suppress crystalline silica dust. Wet-rated blades have softer bonds optimised for cooled operation. Dry cutting blades have harder bonds and built-in airflow gullets to dissipate heat. Always check the blade specification — running a wet-only blade dry damages the bond and shortens life dramatically.
Silica dust — the AU compliance issue
Cutting concrete, stone, tile and fibre cement generates respirable crystalline silica (RCS) dust. Australian workplace exposure standards (Safe Work Australia 0.05 mg/m³ over 8 hours) require dust control on any cutting operation that generates RCS. Wet cutting plus on-tool extraction is the standard control hierarchy. Operators must wear at minimum a P2 respirator for any silica-generating work.
Blade sizes and saws
AIMS stocks diamond blades to suit angle grinders (100 mm, 115 mm, 125 mm), circular saws (185 mm, 235 mm) and tile saws (200 mm, 250 mm). Brands include Austsaw, Bordo TradeCut and other established Australian-distributed ranges. For wood and metal cutting, see the standard saw blade range or cutting wheels.

Q: What's the difference between a continuous rim, segmented rim and turbo rim diamond blade?
A continuous rim is an unbroken diamond edge that gives the cleanest cut with minimum chipping — used for ceramic tile, porcelain and glass where finish matters, at a slower cut rate. A segmented rim has diamond segments separated by gullets, giving maximum cut rate and better heat dissipation for hard concrete, brick and demolition work, at the cost of a coarser edge finish. A turbo rim is a serrated continuous rim with cooling notches, balancing cut speed and edge quality for general masonry, stone and brick work.
Q: Why does a hard-bond diamond blade outlast a soft-bond blade on asphalt or soft sandstone?
The bond holding the diamond particles has to wear at the right rate to keep exposing fresh diamond, or the blade stops performing. A hard-bond blade holds up longer against soft, abrasive materials like asphalt or soft sandstone, where a soft bond would wear away too quickly. A soft-bond option is the better fit for hard materials such as cured concrete or porcelain instead, because the harder material wears that softer bond just enough to expose new diamond as it works.
Q: Why does running a wet-rated diamond blade dry destroy it within seconds?
Wet-rated blades have softer bonds optimised for water-cooled operation. Without that cooling, the bond overheats almost immediately and blade life is dramatically shortened — sometimes within seconds of dry operation. Blades built for dry operation instead use harder bonds and airflow gullets to manage heat without water. The two types aren't interchangeable just because they look similar, so always check the rating before switching between wet and dry work.
Q: What respirator rating is required for cutting concrete or tile in Australia?
Cutting concrete, stone, tile and fibre cement generates respirable crystalline silica (RCS) dust, and Safe Work Australia's exposure standard (0.05 mg per cubic metre over 8 hours) requires dust control on any operation producing it. Wet operation combined with on-tool extraction is the standard control method, and operators must wear at minimum a P2 respirator for any silica-generating work — this requirement applies regardless of whether the blade itself is rated for wet or dry use.
Q: What diameter diamond wheel fits an angle grinder versus a tile saw?
Diameter has to match the tool: angle grinders commonly take 100mm, 115mm or 125mm; circular saws take 185mm or 235mm; tile saws take 200mm or 250mm. Beyond diameter, also check the maximum-RPM rating matches or exceeds the tool's spindle speed — a wheel rated below the tool's RPM is a genuine safety risk, not just a performance mismatch.
