Diamond Concrete Blade is laser welded, the segment style is segmented with key-slot, in this state we make the segmented saw blade have high strength and also improve its cutting performance.
The laser welded concrete saw blade can be installed on handheld saw, floor saw, walk-behind saw, using for dry or wet cutting concrete, cured concrete, green concrete reinforced concrete cutting.
Features of Concrete diamond saw blade
If your customers are cutting reinforced concrete — not just plain slab, but concrete with embedded rebar, structural walls, or aged infrastructure — a standard segment blade will underperform fast. Segments chip, cooling channels clog with debris, and cutting speed drops the moment the blade hits steel. This is exactly the problem our Array Pattern segment, laser welded blade is engineered to solve, and it's why we designed this SKU as a dedicated product rather than a generic "concrete blade."
As a laser welded concrete blade manufacturer with our own in-house welding line, we built this blade specifically for buyers who are sourcing for reinforced concrete demolition, structural renovation, road and bridge cutting, and infrastructure retrofit projects — applications where segment retention and cutting consistency under rebar contact directly affect your customers' job-site downtime and return rate.
1). Used for professional cutting in road and floor construction.
2). Both Dry and Wet Use.
3). Different Cutting slots have a different function, narrow U or key slot give a wider segment and longer lifetime. Wider U slot prevents clogging.
4). Extra soft- Soft- Medium bond hardness options all kinds of concretes with hard to soft aggregates.
5). Different grade to choose.

Buyers sourcing from a catalog often can't tell one "laser welded concrete blade" from another until they see the segment design side by side. Here's how this SKU stacks up against the other laser welded options we produce, so you can match the right blade to the right job before you quote your customer:
| Blade | Segment style | Best suited for | Not recommended for |
|---|---|---|---|
| Array Pattern (this page) | Key-slot segmented | Reinforced concrete, rebar-heavy demolition, structural renovation | Light-duty masonry where cost per piece matters more than rebar resistance |
| Protective/Turbo Segment (155) | Turbo with protective segment | General concrete, masonry, asphalt — mixed material job sites | Sustained rebar contact — turbo segments are optimized for cooling and speed, not retention under steel |
| General Purpose (link) | Standard segmented | Contractors cutting several different materials with one blade | Dedicated reinforced concrete work — versatility trades off against rebar-specific retention |
| Turbo Blade for Concrete Cutting (link) | Narrow U-slot turbo | High-speed cutting where debris clearing and noise reduction matter most | Reinforced concrete where segment retention under rebar is the priority over raw speed |
Application
Most general-purpose concrete blades use a straight or standard segmented edge. Ours uses an array pattern, key-slot segment design — a mechanical notch pattern cut into each segment before welding. This does two things a standard segment can't:
It creates a self-sharpening effect as the segment wears, keeping the diamond exposed and cutting speed consistent through the full service life of the blade, instead of dulling and slowing down halfway through.
The key-slot geometry increases the contact surface between the segment and the steel core, which — combined with our laser welding process — gives significantly higher segment retention when the blade is cutting through embedded rebar and mixed-density reinforced concrete.
This is the core reason to buy from a laser welded concrete blade manufacturer that controls its own segment design and welding process, rather than a trading company reselling a generic catalog blade.
Materials: Reinforced concrete, cured concrete, concrete block, masonry, brick — both wet and dry cutting
Machines: Handheld circular saw, angle grinder, table saw, floor saw
Typical end-use jobs: Demolition and renovation of reinforced concrete walls and slabs, opening cuts for doors/windows/utility penetrations, infrastructure and road-edge cutting, general contractor and rental-fleet resale
If your buyers are sourcing for handheld or table saw use specifically on reinforced structures, this blade is the correct match — not our wall saw or ring saw lines, which are built for track-mounted, large-diameter cutting instead.
We work directly with hardware distributors, tool wholesalers, and construction equipment importers who need private label or custom-spec production, not just off-the-shelf stock. As a factory-direct laser welded concrete blade manufacturer, we offer:
Custom segment height, diameter, and packaging under your own brand
Sample production before batch commitment
Batch lead time of approximately 3 weeks for standard orders; sample lead time shorter — confirm current timelines with our sales team for your specific spec
Flexible MOQ discussion for new accounts testing the market
Delivery Time
Our leading time will be about 4 weeks for the batch order.
What's the actual difference between the array pattern segment and a standard turbo segment?
A turbo segment is optimized for cooling and debris clearance, which gives faster cutting speed on general concrete and masonry. The array pattern, key-slot segment is optimized for mechanical retention — it's designed to keep the segment locked to the core when the blade is cutting through embedded rebar, where a turbo segment is more prone to premature wear or chipping. Choose based on your end customer's material mix, not just price.
Can you produce this blade under our own brand and packaging?
Yes, private label and custom packaging is available for distributor and wholesaler accounts, including custom segment specs on request. See the OEM/ODM section above for what we typically support.
How do you package and ship the blades?
Blades are packed to withstand international freight, and we can accommodate custom packaging requirements for distributor branding. We ship by commercial express (UPS/DHL/FedEx) for smaller orders and by air/sea/land for bulk shipments, depending on your volume and destination.
Is this blade suitable for wet cutting only, or dry cutting as well?
Both. The blade is designed for universal wet and dry cutting, so it can be used on handheld saws, table saws, and floor saws depending on your job-site setup.

How is the quality?
First, we have a very serious control system.
Second, in the face of different markets, we have different quality levels. The main promotion for Euro and US markets is the premium level. The main promotion for the Middle East Market is the standard level.
Third, the different quality level has different cutting speed and working life.
