Alpha® Eclipse Q High-Performance Dry Flush-Cutting Blade
The Alpha® Eclipse Q is a high-performance turbo blade engineered for flush cutting and 90-degree inside-corner work on tile, brick, block, concrete, slate and natural stone — including granite. An 8mm tall diamond layer delivers long blade life and consistent, chip-free cutting on common building materials. The Eclipse Q is paired with the Alpha® Quad Drive or Flange Adapter system so it can run safely on most high-speed angle grinders found in stone and construction shops.
Features
- Specially designed for flush cutting and 90° inside corners
- 8mm tall diamond layer for extended blade life
- Smooth, chip-free performance on medium-to-soft granite (also cuts hard varieties)
- Available 5", 6", 7" and 8" with 20mm Quad Drive, 7/8" Quad Drive or flanged 8-hole mount
- Wet- or dry-cuttable — cutting wet extends life and controls silica dust
- Requires Alpha Quad Drive or Flange Adapter for high-speed angle grinders

- Confirm the blade arbor (20mm Quad Drive, 7/8" Quad Drive, or 20mm 8-hole flange) matches the Alpha adapter on your grinder.
- Mount the blade with the proper Quad Drive (BAH/AAH) or Flange Adapter — never run the Eclipse Q without an adapter.
- Check the grinder's max RPM is at or below the blade's rated speed (12,200 RPM for 5", 10,100 RPM for 6", 8,400 RPM for 7", 7,400 RPM for 8").
- Make light passes for flush cuts and 90° inside corners; let the blade do the work to avoid chipping.
- For best dust control and longer life, cut wet whenever the substrate and grinder allow it.
- Do not use the Eclipse Q for groove cutting — use the Alpha® Groove Cutter for that application.

What materials can the Eclipse Q cut?
Tile, brick, block, concrete, slate and natural stone including granite. It is best suited to medium-to-soft granite, but will also cut harder varieties.
Can I run the Eclipse Q wet?
Yes. Wet cutting generally extends blade life and keeps harmful silica dust out of the air.
Why must I use a Quad Drive or Flange Adapter?
The Eclipse Q is engineered to run on the Alpha Quad Drive / Flange Adapter system. It must always be paired with the proper adapter — never mount it directly to a grinder spindle.
What is the diamond layer height?
8mm, which gives the blade extended service life compared to standard turbo blades.
Can I use the Eclipse Q for groove cutting?
No. Use the Alpha® Groove Cutter for grooves. The Eclipse Q is built for flush cuts and 90° inside corners.
Can I mount it on a polisher?
No. Polisher RPM is too low; use a high-speed angle grinder rated at or above the blade's max RPM.
