Quick Answer
Cutting Method
For Nordic underfloor heating contractors, grooving Fermacell and other plaster-based flooring materials requires a blade that balances cutting efficiency, groove consistency, wear resistance and stability during repetitive work.
The SANG 125mm PCD Segment Diamond Saw Blade is developed for professional floor-heating grooving applications and is designed to help contractors achieve:
Therefore, professional buyers should evaluate more than the purchase price of one blade. Cutting meters, tool life, productivity and total cost per meter are equally important.
1. Why Does Fermacell Floor Grooving Require the Right Blade?
Fermacell plaster-based floors have different cutting characteristics from conventional concrete and masonry materials.
For Nordic underfloor heating contractors, important considerations include:
A conventional diamond blade designed for reinforced concrete does not automatically deliver the best performance on Fermacell flooring.
Professional floor-heating grooving therefore requires blade selection based on:
Material + Machine + Groove Requirements + Working Volume
2. What Is a PCD Segment and Why Does It Matter?
PCD stands for Polycrystalline Diamond.
PCD segments use polycrystalline diamond material to provide efficient material removal and controlled cutting performance when properly matched to the application.
For professional floor heating grooving, the segment does more than determine whether a blade can cut. It can also influence:
SANG develops its PCD segment structure, diamond specification and bond formulation according to different cutting applications, helping the 125mm blade meet the requirements of professional floor-grooving work.
3. SANG 125mm PCD Floor Heating Diamond Blade
The SANG 125mm Floor Heating Cutter Diamond Saw Blade is developed for professional floor-grooving applications.
Key Advantages
High-Efficiency Cutting
The PCD segment design is engineered for efficient material removal and can help improve productivity during repetitive grooving.
Stable Cutting
The blade and segment structure are designed to support controlled and stable cutting performance.
Wear Resistance
PCD cutting technology can provide suitable wear characteristics for repetitive professional applications, helping contractors manage blade consumption.
125mm Diameter
The 125mm format is suitable for compact professional grooving equipment and indoor floor-heating applications.
Application Matching
SANG can evaluate blade specifications according to the customer's material, machine model, groove dimensions and expected working volume.
4. SANG 125mm PCD Blade vs. Conventional Diamond Blade
For professional contractors, the key question is not simply “Which blade costs less?” but “Which blade can complete more meters of grooving at a lower overall cost?”

Purchasing Focus
Cost per meter
Price per blade
Before purchasing, contractors and procurement managers should evaluate the following factors.
Material
Confirm whether the floor is Fermacell or another plaster-based flooring material.
Machine
Check:
Groove Requirements
Confirm:
Groove width
Groove depth
Groove spacing
Heating pipe dimensions
Working Volume
Estimate the number of meters to be cut per day, week or project.
Tool Life
Instead of asking only how long one blade lasts, evaluate the actual number of meters cut per blade.
Cost per Meter
A more useful purchasing formula is:
Total Blade Cost ÷ Actual Cutting Meters = Blade Cost per Meter
This provides a more meaningful comparison than purchase price alone.
