Types of Burnishing Tools
ID Multi-Roll Burnishing Advantages
Special tools with burnishing lengths longer than shown are available and will be quoted upon request.
Special deep hole tools with bodies smaller than the cages are available from .375” to 1.187”.
Through holes and blind holes
Tools with relieved rolls are used for through holes (Roll Style 1).
These tools are self-feeding and a release clearance is required. The through rolls cannot burnish as close to the bottom of the hole as blind end rolls (Roll Style 4). These rolls are interchangeable within the standard cages.
Full bottoming rolls
Used in blind hole applications to minimize the release clearance (Roll Style 8).
