Contact Drawbar Force Bump-Off Distance 2. First contact position: In this position, the clamping components make their first contact with the taper of the tool. • The drawbar begins to retract, causing the locking balls to climb out of their pockets and begin traveling onto the lockrod ramps. • As the locking balls rise, they begin to draw the tool into the taper. • Stand-off is the distance between the two gage faces when the two tapers make first contact. This gap is a result of the interference between the two tapers.
