Extended Product Information

FAQs

What is the maximum thickness of material this blade can cut?

The Marcrist FZ850 is designed to cut materials up to 3cm (30mm) thick, particularly vitrified paving and outdoor porcelain slabs.

Can this blade be used on any angle grinder?

It is compatible with most standard angle grinders that have a 22.23mm bore size. Always check your grinder's specifications before mounting.

Will this blade chip delicate materials like porcelain?

No, the FZ850 is specifically engineered to provide an extremely precise and chip-free cut, even through the hardest materials like outdoor porcelain.

How long does the blade typically last?

The blade features premium 10mm segments and a special bond composition for an extremely long life, offering a low cost per cut. Actual lifespan depends on usage intensity and material hardness.

What safety standards does this blade comply with?

The Marcrist FZ850 complies with the highest European safety standard, EN13236.

What if I'm not satisfied with the blade's performance?

Marcrist offers a 30-day money-back guarantee if you are not totally satisfied with the performance of the blade from the date of purchase.

Can I use this blade for dry cutting only?

While optimized for dry cutting, water can be used for dust suppression, which may also help with cooling during very demanding tasks. Ensure the blade is dry before storing.

Troubleshooting

Blade cutting slowly or inefficiently

Ensure the blade is rotating in the correct direction. Check if the material being cut is within the specified thickness (up to 3cm) and type compatibility. The blade might be dulling; try to "sharpen" it by cutting into a softer abrasive material like concrete block for a short period.

Excessive chipping on the material edge

This blade is designed for chip-free cutting; excessive chipping may indicate the material is harder or thicker than specified, or the blade is worn. Reduce the cutting speed and pressure. Ensure the blade is correctly mounted and not damaged.

Blade is noisy or vibrates excessively

Check that the blade is securely tightened on the grinder spindle. Ensure the grinder's flange is clean and correctly seated. Inspect the blade for any damage or warping. Use of the reinforced flange design helps minimize vibrations, but ensure it's functioning as intended.

Blade gets extremely hot during use

Allow the blade and material to cool down periodically. Ensure you are not applying excessive pressure. Use dust suppression methods (like water spray) if appropriate, which can also aid cooling.

Pros and Cons

Pros

  • Cuts hard materials extremely fast.
  • Provides a chip-free finish on delicate materials.
  • Offers a very long service life.
  • Minimizes vibrations for better user comfort and control.
  • High safety standards compliance.
  • Economical due to low cost per cut.

Cons

  • Optimized for specific materials (up to 3cm thick porcelain/vitrified slabs); may not be the most efficient for softer materials.
  • Requires a compatible angle grinder with a 22.23mm bore.
  • As a specialized tool, its cost might be higher than general-purpose blades.

Setup, Compatibility & Care

Setup:

  1. Ensure the angle grinder is switched off and unplugged.
  2. Remove the old blade, ensuring the grinder's spindle nut is loosened.
  3. Mount the Marcrist FZ850 diamond blade onto the grinder's spindle, ensuring the direction of rotation arrow on the blade matches the grinder's rotation.
  4. Tighten the spindle nut securely using the appropriate spanner.
  5. Ensure all safety guards are correctly positioned.

Compatibility:

  • Bore Size: The blade has a 22.23mm bore, compatible with most standard angle grinders that accept this fitting. Check your grinder's specifications.
  • Tool Type: Designed for use with handheld angle grinders.
  • Material Thickness: Optimized for materials up to 3cm (30mm) thick.

Care & Maintenance:

  • Cooling: For extended use, especially in demanding materials, occasional breaks to allow the blade to cool can prolong its life.
  • Cleaning: After use, brush away any dust or debris from the blade segments. Avoid using water unless specifically required for dust suppression during cutting, and ensure the blade is dry before storage.
  • Storage: Store the blade in a dry place, away from moisture, to prevent corrosion.
  • Inspection: Regularly inspect the blade for any signs of damage, wear, or segment loss before each use.
