Saw Blades for Cutting Concrete –
Efficiency, Precision and Quiet Operation
Professional prestressed concrete saw blades are a key factor in hollow-core slab cutting. The blades are tailored to meet customer‑ and factory‑specific requirements, influenced by the customer’s machinery, concrete mix design and aggregates.
We continuously optimize the overall solution to suit Nordic aggregates and mix designs, both for different market regions and individual customers. Saw blades designed for hollow‑core slab cutting are delivered directly from our warehouse in Vantaa.
Additional diameters are available upon request. The design of the bore holes is customized according to the type of cutting machine.
Standard diameters and dimensions
Most common bore sizes available from stock
- 60 mm + 2 additional pin holes
- 100 mm
- 130 mm + 6 additional pin holes
Other sizes are available upon request.
Factors Affecting Cutting Speed
Cutting speed is influenced by slab thickness, curing stage, aggregate type and number of strands, and strand reinforcement.
Optimal speed (limestone aggregates):
- 200 mm slab: 1.8–2.0 m/min
- 500 mm slab: 0.5–0.8 m/min
Factors Affecting Blade Life
Blade life is affected by the aggregate type, curing stage, and the maintenance condition of the machine.
Measured Noise Levels
Noise levels were measured using a 1100 mm saw blade on an ELEMATIC saw during cross‑cutting.
- Normal core: Solid steel body – most economical, stable in cutting – 102–105 dBA
- DTS core: Laser‑cut slots for noise reduction – approx. 15–20% more expensive, moderate damping – 100–102 dBA
- DTE core: Laser‑cut slots filled with epoxy – significant noise reduction – 97–99 dBA
- LN (Sandwich) core: Copper foil between two steel layers – best noise reduction, approx. 50% more expensive – 94–97 dBA
Segment Qualities and Bonding Technologies
We offer several segment grades tailored to the customer’s working conditions and the concrete aggregate. GE LINE technology represents an innovative bonding system that enables higher productivity (speed, blade life) and is environmentally friendly (free of heavy metals). For maximum efficiency, we combine the bonding system with the correct segment shape and internal structure.
