Diamond saw blades
Diamond saw blades. Cut faster, change blades less often.
For wall saws, floor saws, hand-held cut-off saws and stone saws. We match the bond to your concrete, aggregate and rebar – so you pay for metres cut, not for the blade.

Choose a blade
Machine, material, diameter – and you have a match
Tick what you cut and what you cut it with. For every diameter we show the approximate cutting depth. Add the blade you choose to your quote request in one click.
No series match these filters. We also make special designs – tell us the machine and material and we will match a blade.

Typical blade sizes by machine
Diameter and bore follow from the machine; segment height and width follow from the material and power. The table shows the market standard – special designs are matched individually.

How deep will your blade cut?
Approximate maximum cutting depth: (blade Ø − flange Ø) / 2.
Cutting depth up to 330 mm
With a Ø 140 mm flange. Actual depth depends on the machine and blade guard.
What operators come to us with
Four problems that cost more than the blade
Each one comes from the choice of bond, segment or operating parameters. Each one can be fixed.
-
The blade stops cutting
Cause: glazing – the bond is too hard for the aggregate, so the diamonds go blunt and are not exposed.
Fix: a softer bond for hard aggregate; in the short term, dress the blade in an abrasive material.
-
Slow cutting through rebar
Cause: grit with low impact strength, diamond concentration too low.
Fix: a segment with impact-resistant grit and higher concentration, cut wet.
-
Lost segments
Cause: overheating, core undercutting in asphalt, a weak joint.
Fix: segments with core protection, controlled cooling, a strength test of every segment.
-
Vibration and run-out
Cause: a bent or overheated core, wrong rotational speed.
Fix: run-out inspection, a core matched to machine power, retipping with an inspection report.
We select the bond by one rule: hard material – soft bond, abrasive material – hard bond.

Diamond blade retipping
Segments worn out? The core keeps cutting.
We retip every blade type on this page – other brands included. New segments from our own production, run-out check and a written report. You ship the blades to us after we have agreed the scope.

Try it on your own concrete before you buy a series
A technical advisor matches a blade to your material and machine, then you compare it on site with the blade you use today: m²/h and metres per segment. Delivery terms are agreed with you.

How do I choose a diamond blade for concrete?
Start with the machine – it determines the diameter, bore and power. Then the material: aggregate hardness and the amount of rebar. Hard aggregate (granite, basalt) needs a soft bond; abrasive or green concrete needs a hard one. With dense rebar, impact-resistant grit and wet cutting matter most.
Why does a diamond blade stop cutting?
Usually it has glazed: the bond is too hard for the material, the diamonds go blunt and no new ones are exposed. Cutting an abrasive material (brick, sandstone) helps in the short term; a blade with a softer bond is the lasting fix.
What is the difference between an asphalt blade and a concrete blade?
Asphalt is soft but highly abrasive. An asphalt blade has a hard bond and segments that protect the core from undercutting. A concrete blade has a bond matched to the aggregate and grit that withstands rebar. Swapping them leads to rapid wear or no cutting at all.
Wet or dry cutting?
Large blades (floor saws, wall saws, table saws) run wet – water cools the segment and flushes out the slurry. Dry cutting means short cuts with blades designed for it, with cooling breaks. Dry cutting creates dust – use extraction and respiratory protection.
How deep does an 800 mm blade cut?
Roughly half the difference between the blade and flange diameters. On a wall saw with a flange of about 140 mm, an 800 mm blade cuts about 330 mm deep. Check your setup in the depth calculator above.
Do your blades comply with EN 13236?
[TO BE CONFIRMED: EN 13236 compliance, core markings, downloadable declaration of conformity]
Can a worn blade be retipped?
Yes, if the core is straight, free of cracks and the segment seats are intact. We replace the segments, check run-out and issue a report. See diamond blade retipping.
