Internal Diameter Roll Burnishing Tool

A proven method for accurate sizing and finishing of bores.

The cold working action will improve minor surface irregularities and tool marks resulting in a low microinch surface finish.

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.

  • Size Range: 3.9mm – 165mm
  • Application: Hole ID Sizing, Finishing and Hardening
  • Low Microinch Finish
  • Accurate Sizing

ID Multi-Roll Burnishing Products

Through Rolls

Rolls with greater radius relief are used for through holes. These tools are self-feeding & a release clearance is required.

These rolls are interchangeable between blind and through cages.

Blind Rolls

Blind rolls burnish closer to the bottom of a hole than through rolls.

These rolls are interchangeable between blind and through cages.

Bottoming Rolls

Used in blind hole applications to burnish as close as possible to the bottom of the bore.

These rolls are not interchangeable between blind or through cages.

The Advantages of ID Multi-Roll Burnishing


Produces a 4 to 8 Ra surface finish in one pass.

Improves surface irregularities and tool marks.


Burnishing is a repeatable and consistent process

Fast cycle times – measured in seconds, not minutes!


ID burnishing tools produce accurate sizing in .0001″ increments.

Roller burnishing results in 25% size improvement in steel and up to a 50% improvement in high ductility materials.


Burnishing increases the surface hardness through the cold working process and compressive forces.

Increases metal’s resistance to fatigue and failure at stress points.

Produces a dense and uniform surface.


Burnishing is effective for many different part configurations.

Suitable process for a variety of metals – all ductile metals can be burnished!

Multi-roll burnishing tools are adjustable to cover a size range.


Eliminates secondary machines and set ups.

Eliminates secondary processes such as grinding, honing and polishing.

Elliott burnishing tools feature long lasting and replaceable wear parts, reducing total cost over the life of the tool.
