Description

Alpha® Libero Electroplated Dry-Cutting Blade

The Alpha® Libero is an electroplated diamond blade engineered for chip-free dry cutting of softer stones — marble, travertine, soapstone, alabaster, onyx and limestone — on angle grinders, stone cutters, and (in 7") worm-drive saws. Five sizes from 4" to 7" cover everything from small detail work to full-depth slab cuts.

Features

  • Electroplated diamond edge engineered for chip-free cuts on softer stones
  • Recommended for marble, travertine, soapstone, alabaster, onyx and limestone
  • Runs dry — running wet further extends blade life
  • Five sizes (4" / 4-1/2" / 5" / 6" / 7") for grinders, stone cutters and 7" worm drives
  • NOT for granite or other very hard stones (electroplated diamonds will dull quickly)

  1. Match the blade size to your tool and confirm the blade Max RPM exceeds your tool RPM.
  2. Mount the blade with the correct arbor bushing for your spindle (7/8", 5/8", 20 mm, or diamond knockout per part number).
  3. Lower the blade fully onto the work and let blade weight do the cutting — do not force feed.
  4. Use a steady, light-pressure pass; back the blade out and re-enter to clear the kerf on deep cuts.
  5. For longer life, run with light water mist where the application allows (still rated for dry use).
  6. Inspect the diamond layer after each job — replace once the electroplated edge is worn smooth.

What materials can I cut with a Libero blade?

Softer stones: marble, travertine, soapstone, alabaster, onyx and limestone. It also handles fiberglass when used dry.

Can I use Libero on granite?

No. Granite is too hard for an electroplated diamond edge — the diamonds will dull almost immediately. Use a sintered or brazed blade for granite.

Can I use Libero wet?

Yes. Libero is designed to run dry, but adding water will significantly extend the life of the blade.

What is the advantage of a stone cutter over an angle grinder?

A stone cutter provides better stability and accuracy than a handheld angle grinder, especially for long straight cuts and miters.

Can I use Libero on fiberglass?

Yes — use it dry on fiberglass.

Which size do I need?

Match the blade diameter to your tool. 4"-6" sizes fit angle grinders and small stone cutters; 7" fits 7" worm drives and larger angle grinders.
