Product Information

Full details

This Bosch EXPERT Cordless Circular Saw Blade is designed for professionals and DIY enthusiasts who need to cut fibre cement materials efficiently with their cordless circular saws. Its key benefit is maximising battery life and providing a smooth cut through abrasive materials, thanks to its thin kerf and polycrystalline diamond (PCD) teeth. A potential caveat is its specialised nature, meaning it's optimised for fibre cement and may not be the best choice for general-purpose wood cutting.

FAQs

What is the primary benefit of the extra-thin kerf?

The extra-thin kerf reduces friction and the amount of material removed during the cut. This conserves energy, leading to significantly longer battery life for cordless saws.

Can this blade be used for cutting wood?

While it might cut wood, this blade is specifically engineered for abrasive materials like fibre cement. Using it on wood will not provide optimal results and may wear the PCD teeth prematurely for their intended purpose.

How long do the PCD teeth last?

Polycrystalline Diamond (PCD) teeth are extremely hard and durable. This blade is designed for an extremely long lifetime, especially in abrasive materials, far exceeding conventional carbide-tipped blades in such applications.

What does the ProteQtion coating do?

The ProteQtion coating is designed to reduce friction during the cut, prevent rust formation on the blade, and contribute to a highly durable and consistent cutting performance over the blade's lifespan.

Can PCD blades be sharpened?

No, PCD blades are not designed to be resharpened like carbide blades. Once the PCD teeth have worn down or are damaged, the blade requires replacement.

What does '4T' mean on the blade specification?

'4T' refers to the number of teeth per inch (TPI). In this case, it means the blade has 4 teeth per inch, indicating a coarse tooth configuration suitable for fast material removal in specific applications like fibre cement.

Is this blade suitable for wet cutting?

The product information does not specify suitability for wet cutting. It is recommended to use this blade for dry cutting of fibre cement as intended to maintain its performance and longevity.

Troubleshooting

Blade is not cutting cleanly.

Ensure the blade is correctly installed with the cutting direction aligned with the saw's rotation. Check for any damage to the PCD teeth. If teeth are worn or damaged, the blade needs replacement.

Reduced battery life despite using the blade.

Verify that the thin kerf is not obstructed. Ensure the material being cut is within the intended use (fibre cement). Check saw maintenance for other potential power drains.

Blade binding or snagging.

Ensure a straight cut is being maintained and the material is properly supported. Check that the blade is not warped and the saw's arbor is true.

Rust spots appearing on the blade.

While the ProteQtion coating prevents rust, prolonged exposure to moisture can still cause minor surface rust. Clean with a dry cloth. The coating's effectiveness remains.

Pros and Cons

Pros

  • Significantly extends battery life on cordless saws due to reduced friction.
  • PCD teeth ensure exceptional longevity in abrasive materials.
  • Provides a smooth, clean cut in fibre cement.
  • ProteQtion coating offers rust prevention and reduced friction.
  • Adaptable fit for a wide range of cordless circular saws.

Cons

  • Primarily designed for fibre cement; may not be optimal for other materials.
  • PCD teeth can be more brittle than carbide if subjected to extreme lateral force.
  • Higher initial cost compared to standard blades.
  • Requires correct usage to maintain performance and avoid damage.

Setup, Compatibility & Care

Setup:

  1. Ensure the saw is unplugged or the battery is removed before blade installation.
  2. Select the appropriate reduction ring for your saw's arbor size if needed. The standard bore is 30mm.
  3. Mount the blade onto the saw's arbor, ensuring the cutting direction arrow on the blade aligns with the saw's rotation.
  4. Secure the blade using the saw's locking mechanism.

Compatibility:

This blade is compatible with various cordless circular saws, including mitre saws, plunge saws, and handheld circular saws, provided the arbor size matches (with or without reduction rings).

Care:

  • Keep the blade clean from dust and debris, especially from abrasive materials.
  • Avoid dropping the blade or subjecting it to impact, which can damage the PCD teeth.
  • Store the blade in a dry place to prevent rust, although the ProteQtion coating offers significant protection.
  • If the blade becomes dull or performance degrades, it typically indicates the PCD teeth have worn significantly and the blade needs replacement. PCD blades cannot be resharpened.
