Cogsdill Burraway Tool - one-pass solution for hole deburring
Upon entry, spring tension holds the cutting blade in the extended position as it removes the burr on the front of the hole.
As the feed load increases, the pre-set spring tension is exceeded and the blade retracts automatically as the tool passes through the workpiece
Spring tension again causes the blade to extend as it emerges from the ID of the part; the burr is removed on the back side of the hole on the return stroke.
