FAQs
What materials can this blade cut?
This blade is designed for cutting all types of concrete, including reinforced concrete, as well as non-abrasive building products like breeze blocks, porous bricks, and natural stone.
What is the bore size of this blade?
The blade has a 20mm bore. You may need to use an adapter ring if your saw has a different spindle size.
How long will this blade last?
The blade offers extended life and consistent performance due to its high-quality steel center and 10mm segment height. Actual lifespan depends on usage intensity and the materials being cut.
Can I use this blade on an angle grinder?
Yes, the product description mentions suitability for use in angle grinders, provided the grinder's specifications match the blade's RPM and speed ratings, and the bore size is compatible (potentially with an adapter).
Is this blade suitable for cutting asphalt?
Yes, the description specifically mentions compatibility with cutting asphalt.
What is the segment height?
The segment height is 10mm, which is substantial for aggressive cutting and provides good longevity.
Does the blade come with an adapter for smaller saws?
The product information does not specify if an adapter is included. However, a 20mm bore is standard for many professional machines, and adapters are widely available if needed.
Troubleshooting
Blade not cutting effectively
Ensure the blade is mounted in the correct direction of rotation. Check for excessive wear on the diamond segments. The material being cut may be too abrasive for this blade; consider a different blade type if cutting materials other than concrete or non-abrasive stone.
Blade chipping or segment damage
Stop immediately. Inspect the blade for damage. This can be caused by hitting rebar, excessive force, or cutting inappropriate materials. Do not use a damaged blade. Ensure proper cooling if applicable.
Blade vibrates excessively
Check that the blade is securely mounted and that the flanges are clean and flat. Ensure the saw's spindle is not damaged. Verify the blade is not warped or damaged.
Blade gets too hot
Reduce cutting pressure and allow the blade to cool. Use water cooling if possible. Ensure the saw is operating at the correct speed and the blade is not dull.
Pros and Cons
Pros
Excellent cutting speed on concrete and masonry.
Long-lasting performance due to durable construction.
Compatible with many common professional saws.
Ideal for heavy-duty civils and groundwork.
10mm segment height offers good cutting depth and wear resistance.
Cons
Primarily designed for concrete; may not perform optimally on other materials.
Requires appropriate safety equipment and operating procedures.
A 20mm bore might require an adapter for saws with smaller spindle sizes.
Setup, Compatibility & Care
Setup:
Ensure the saw is switched off and disconnected from its power source.
Mount the blade onto the saw spindle, ensuring the blade's rotation direction arrow matches the saw's direction of rotation.
Secure the blade using the provided flange and locking nut, tightening appropriately.
If your saw's spindle is smaller than the blade's 20mm bore, use the correct adapter ring.
Double-check that the blade is securely fastened and rotates true before operation.
Compatibility:
Machines: Designed for petrol saws and bench-mounted cut-off machines.
Bore Size: 20mm bore. Check if an adapter is needed for your specific saw (common adapters reduce to 22.23mm or 25.4mm).
RPM/Speed: Ensure your saw's maximum RPM (6600 RPM) and speed (100 m/s) are compatible with the blade specifications.
Care:
Storage: Store the blade in a dry environment, away from moisture, to prevent corrosion.
Cleaning: After use, clean off any dust and debris. Avoid harsh chemicals.
Inspection: Regularly inspect the blade for damage, excessive wear, or missing segments. Do not use a damaged blade.
Cooling: For prolonged use, consider using water cooling to reduce dust and extend blade life, if your saw permits.
