Upgrading your 770M+ or 1100M+ mill to a BT30 spindle is a great upgrade to add more tool holding strength. Additionally, for the 1100M+, this upgrade increases your top spindle speed up to 10,000 rpm.
Note: The M+ update is a requirement before completing the BT30 upgrade. However, these updates can be completed at the same time. For more information, see 1100M+ Servo Upgrade .
