Bit & Rig Compatibility

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

Spindle Connection: 1-1/4"-7 UNC Male (Outer) / 5/8"-11 UNC Female (Inner)

This machine utilizes a 1-1/4"-7 UNC Male (Outer) / 5/8"-11 UNC Female (Inner) spindle. Diamond core bits matching this connection thread directly without adapters. Mismatched threads require a documented rigid arbor adapter.

Compatible core bits

Mechanical fit is not the same as a safe operating-speed fit. Bit published max RPM wins when lower than the machine gear.
