14 Inch Diamond Blade for Cured Concrete (350mm): Walk-Behind Saw Guide
The 14 inch diamond blade for concrete (350 mm) is the entry size for walk-behind and flat saws. Designed for cured concrete, laser-welded or high-frequency-welded segments deliver excellent cutting speed and long life on floors, driveways and slabs.
Why Cured Concrete Needs a Dedicated Blade
Cured (aged) concrete is hard and dense — very different from green (fresh) concrete. A cured-concrete blade uses a bond matched to hard material so worn diamonds release steadily and cutting speed stays high throughout the blade's life.
Specifications (Construction Blade Series)
| Diameter | Segment height | Thickness | Segments | Bore |
|---|---|---|---|---|
| 350 mm (14") | 10/12/15 mm | 3.2 mm | 24 | 25.4/27/50 mm |
| 400 mm (16") | 10/12/15 mm | 3.2 mm | 28 | 25.4/27/50 mm |
| 450 mm (18") | 10/12/15 mm | 3.6 mm | 31 | 25.4/27/50 mm |
| 500 mm (20") | 10/12/15 mm | 3.6 mm | 35 | 25.4/27/50 mm |
Advantages
- ~125 mm cutting depth at 350 mm diameter — covers most slab work.
- Laser/high-frequency welding: segments withstand the heat and load of machine cutting without detaching.
- Fast, straight cuts with excellent performance and free chipping.
- 15 mm segment height option: maximum life for road and floor contractors.
Selection Tips
- Match bond hardness: hard cured concrete → softer bond; abrasive/green concrete → harder bond.
- Confirm bore (25.4/50 mm) and pin-hole pattern against your saw.
- Cut wet whenever the saw allows — longer life, less dust.
FAQ
Can a cured concrete blade cut asphalt?
Briefly, but asphalt's abrasiveness destroys concrete bonds quickly. Use a dedicated asphalt blade with undercut protection.
What about rebar in the slab?
Quality laser-welded blades handle occasional rebar. Heavy reinforcement calls for a reinforced-concrete bond specification.
How many linear meters does a 350 mm concrete blade last?
Highly variable — from a few hundred meters in hard aggregate to 1,000+ in medium concrete at proper speed and water flow.
