The Alpha® Eclipse II is a high-performance dry diamond blade engineered for general-purpose cutting on tile, brick, block, concrete, slate and natural stone, with superior results on granite. With an 8 mm tall diamond layer for extended blade life and a profile that fits most angle grinders and Alpha® wet stone cutters, the Eclipse II delivers consistent, chip-free cuts on the toughest jobs. It is best suited for medium-to-soft granite classifications and will also cut hard granite.

- Verify the tool RPM does NOT exceed the Max RPM stamped on the blade.
- Mount the blade with the arrow on the blade matching the rotation direction of the tool.
- Tighten the flange firmly using the manufacturer’s wrench; never over-torque.
- Allow the blade to reach full speed before contacting the material.
- Let the blade do the cutting; apply only light, steady feed pressure.
- For dust suppression and longer blade life, cut wet whenever the tool permits.
- Never use an 18 V cordless circular saw — 3,200 RPM is insufficient and causes premature wear.
- After use, run the blade free for several seconds to expel debris before storage.

What is the cutting edge rim height of the Eclipse II blades?
The rim height is 8 mm.
Which granite classifications are recommended for the Eclipse II?
The Eclipse II blades are best suited for medium-to-soft granite classifications; however, they will also cut hard granite classifications.
Can a dry blade be used wet?
Yes. Cutting wet generally increases blade life and eliminates harmful silica dust exposure.
Why use an Alpha® Stone Cutter rather than an angle grinder for 5" or smaller blades?
The AWS-110 or AWS-125 stone cutters provide better cutting stability and increased accuracy since the tool’s base glides across the cutting surface.
Can I use an 18 V cordless circular saw with Eclipse blades?
No. The 3,200 RPM of these circular saws is insufficient for diamond blades and causes premature wear or out-of-round conditions.
What materials can be cut with Eclipse II blades?
The Alpha® Eclipse II Series can be used to cut tile, brick, block, concrete, slate and natural stone, and gives superior results on granite.
