Can I change bits with a Kreg router table without removing the router from the table ? Also with no spindle lock does it require 2 wrenches to change

Thank you for your question. The 1617EVSPK Router comes with both wrenches. You would want to check with your router table manufacturer to see if the bits can be replaced from above the table top. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.
