Wall Saw Blades
Large-diameter laser-welded blades for track-mounted wall saws — built to cut deep through reinforced concrete walls, bridge decks and openings. Tensioned steel cores, an ordered diamond array and EN 13236 speed marking, with flange patterns for Hilti, Tyrolit, Husqvarna and Pentruder machines.
Product Series
The wall, the saw and the aggregate decide the blade. Cut depth sets the diameter, the machine sets the flange and bore, and the aggregate sets the bond. Each blade below is built for a specific cut — not a one-blade compromise.
Reinforced Concrete Wall Saw Blade
The workhorse for reinforced concrete walls and slabs. Laser-welded segments on a tensioned steel core, with an ordered diamond array and a bond tuned to hold its edge through heavy rebar without glazing. The blade you reach for on standard structural cutting.
Deep-Cut Wall Saw Blade
The large-diameter blades for the deepest cuts — thick walls, bridge decks and heavy foundations where a smaller blade can't reach. A flatter, more rigid tensioned core and undercut-protected segments keep the cut straight and the steel core safe at full depth.
Silent-Core Wall Saw Blade
A laser-cut sandwich (silent) core damps noise and vibration for cutting in occupied buildings, hospitals and dense urban sites. The same laser-welded, ordered-array segments — quieter, smoother, and easier on both the operator and the neighbours.

Matching the Blade to the Cut
How diameter maps to cut depth and bond — the starting point for any wall-saw order, then tuned to your saw and aggregate
| Diameter | Depth | Bond | Ideal For |
|---|---|---|---|
| Ø600–700 · 24–28″ | ~220–270 · 8.5–10.5″ | Medium–Hard | Standard walls & openings |
| Ø800–900 · 32–36″ | ~300–350 · 12–14″ | Hard | Thick reinforced walls |
| Ø1000 · 40″ | ~400 · 16″ | Hard | Deep walls & slabs |
| Ø1200 · 48″ | ~500 · 20″ | Hard | Bridge decks, heavy section |
| Ø1372 · 54″ | ~600 · 24″ | Hard | Deepest single-pass cuts |
Getting the Most From a Wall Saw Blade
A wall saw blade is a tensioned core, a laser weld and a flange matched to the machine — these fundamentals decide cut quality, blade life and, above all, safety.
Match the blade to the saw's flange and bore
Wall saws from Hilti, Tyrolit, Husqvarna and Pentruder use specific drive-pin and flange patterns — a 1-3/8″ bore (Hilti, Pentruder, Longyear) or a 60 mm bore (Husqvarna). The blade has to match the machine's bore and pin circle or it won't mount and run safely. This is the first spec, before diameter.
Tip · Always quote the saw make and model — the flange pattern is machine-specific.
Bond to the aggregate — matched backwards
Hard flint or granite aggregate with heavy rebar needs a softer bond that wears fast enough to keep exposing fresh diamond; soft, abrasive concrete needs a harder bond so it doesn't wear out mid-cut. Tell us the aggregate, not just 'concrete'.
Tip · Hard aggregate / heavy rebar → softer bond. Soft / abrasive → harder bond.
Laser welding is non-negotiable at this size
At Ø600mm and up, in rebar, at high peripheral speed, only a laser weld holds the segment to the core. A brazed or sintered joint on a blade this large is a serious hazard — a thrown segment at full RPM is a major incident.
Tip · Wall saw blades → laser-welded only, never brazed.
Let the tensioned core run flat
A wall saw blade is tensioned to run true under cutting load. Feed steadily and let the saw's hydraulics set the rate; forcing it dishes the core, wanders the cut and overheats the rim.
Tip · Let the saw pull — forcing a big blade dishes the core.
Step-cut deep sections
For full-depth cuts, take it in steps — roughly a third of the depth per pass — rather than plunging to full depth at once. Step-cutting controls heat, keeps the kerf straight and protects the segments and core.
Tip · Deep cut → step in thirds, don't plunge full-depth.
Respect the EN 13236 max RPM
Large blades have low maximum RPM — a Ø1000mm+ blade over-speeded can come apart catastrophically. Match the blade's marked max RPM to the saw's arbor speed; never fit a large blade to a faster machine than it is rated for.
Tip · Bigger blade = lower max RPM. Check the mark against the saw.

Frequently Asked Questions
What is a wall saw blade, and how is it different from a normal diamond blade?
A wall saw blade is a large-diameter (Ø600–1372mm) laser-welded diamond blade that mounts on a track-guided wall saw — a hydraulic or electric machine that runs on rails up a wall — to cut deep through reinforced concrete. It is the same family as a circular diamond blade, but a different product: far larger, on a tensioned steel core, with a 60mm bore and machine-specific drive-pin flange, engineered for safety at high peripheral speed in rebar. A hand or floor-saw blade can't reach the depth or take the load.
What diameters do you make, and how deep can each cut?
Ø600 to Ø1372mm (24"–54"). Cut depth is roughly the radius minus the flange: about 220–270mm at Ø600–700, ~350mm at Ø900, ~400mm at Ø1000, ~500mm at Ø1200 and ~600mm at Ø1372. For deeper sections you step the cut or cut from both faces.
Which wall saws do these fit — Hilti, Tyrolit, Husqvarna, Pentruder?
All of them, but the flange and drive-pin pattern is machine-specific. The bore is 60mm; the pin circle differs by manufacturer. Tell us the saw make and model and we cut the correct flange pattern — this is the first thing to confirm on any wall-saw order, before diameter.
What does the CSDA code stamped on a wall saw blade mean?
Blades 12" and larger carry a Concrete Sawing & Drilling Association (CSDA) code in three parts — [operating method]-[media]-[feature]. First letter: W = wet only, D = dry or wet. Second: C = cured concrete, G = green concrete, A = asphalt, R = refractories. Third: F = flat/wall saw, H = hand saw, M = masonry. So a W-C-F blade is wet-only, for cured concrete, on a flat or wall saw. Tell us the code you run — or just the material and saw — and we match the bond and segment to it.
Why laser-welded and not brazed for wall saw blades?
At Ø600mm and up, segments run at high peripheral speed and slam into rebar — the joint heats hard. Laser welding fuses the segment to the steel core with a bond stronger than the steel itself; a brazed or sintered joint can release a segment, and a thrown segment from a blade this large at full RPM is a major safety incident. For wall sawing, laser-welded is the only responsible choice.
What is the ordered diamond array, and why does it matter on a wall saw blade?
Random-set segments drop diamond wherever it falls, so some grit does all the work and the rim wears unevenly. An ordered array spaces every diamond deliberately, so the load is shared and the rim wears flat and predictably — which on a deep, expensive structural cut means a straighter kerf, a longer-lasting blade and fewer blade changes mid-job.
Hard or soft bond — how do I match it to my concrete?
The rule is backwards from intuition: hard, dense aggregate with heavy rebar needs a softer bond (it wears fast enough to keep exposing fresh diamond), while soft or abrasive concrete needs a harder bond (so it doesn't wear out in one cut). Tell us the aggregate type and rebar density and we match the bond — 'concrete' alone isn't enough to spec it.
What is a silent-core wall saw blade?
A blade with a laser-cut sandwich core — two steel layers with a damping interlayer — that absorbs noise and vibration. It runs noticeably quieter and smoother, which matters for cutting in hospitals, schools, occupied buildings and dense urban sites with night-work noise limits. The segments and cutting performance are the same; the core is what changes.
Not Sure Which Blade Your Wall Saw and Wall Need?
Tell us the saw make and model, the wall thickness and aggregate, and the cut depth you need — we'll spec the diameter, bond, core and flange pattern, and can arrange a sample before a production order.
