Bit & Rig Compatibility

Spindle interface, bit connection standards, and rig pairing documentation.

Spindle Connection: 1-1/4"-7 UNC Male (Outer) / G 1/2" Female (Inner)

This machine utilizes a 1-1/4"-7 UNC Male (Outer) / G 1/2" Female (Inner) spindle. Diamond core bits matching this connection thread directly without adapters. Mismatched threads require a documented rigid arbor adapter.
