Bit & Rig Compatibility
Spindle interface, bit connection standards, and rig pairing documentation.
Spindle Connection: 1-1/4"-7 UNC Male
This machine utilizes a 1-1/4"-7 UNC Male 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.
