The Titespot® Angle Head typically does not require a stop block. We have customers who choose to add one for ultra precision orientation or to compensate for machine tool spindle looseness. This defeats the indexability of the head.
A stop block might also be added to machines that do not have through the spindle coolant and need a stop block to introduce the coolant supply to the tool using the combination of a coolant induced tool holder with our straight shank tool. It is still possible to index the Titespot® head using this configuration.
