Multi-roll burnishing tools for accurate sizing, low micro-finishing, and surface hardening of ID holes.
Proven technology with decades of refinement. Common sizes available in stock, including all wear parts.
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”.
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.
Used in blind hole applications to minimize the release clearance (Roll Style 8).
