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.
