Lapidary Blade Compatibility Checker

Check blade diameter, arbor and RPM against documented lapidary saw requirements. Identify mismatches and specifications that need confirmation.

By John Morris·Updated September 10, 2026·How we research

A matching diameter is only the beginning.

Enter the blade’s documented specifications. Missing values remain unknown; this tool will not guess them.

What this checker can establish

It compares recorded blade sizes and arbor dimensions with your inputs and rejects a blade rating below the model’s screening speed. It cannot inspect a blade, a modified machine or an unclear listing.

The variable-speed trim saws are screened at 3,400 RPM. The 10-inch model is screened at 1,740 RPM; manufacturer sources list different fixed-speed values, so your exact machine label and current instructions take priority.

Check maximum thickness, rim construction, clamping and guard clearance separately. Do not use a failed combination or treat a preliminary pass as an endorsement of an unverified listing.
