Types of Burnishing Tools


Low microinch finish

  • Produces a 4 to 8 Ra surface finish in one pass.
  • Improves surface irregularities and tool marks.

Process improvements

  • Burnishing is a repeatable and consistent process
  • Fast cycle times – measured in seconds, not minutes!

Work hardening

  • 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.

Low cost

  • 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.

Easy to use

  • MTG and Elliott burnishing tools require limited training to operate.
  • Easy to maintain and repair.
  • Common repair parts are always stocked!


  • Burnishing is effective for many different part configurations.
  • Suitable process for a variety of metals – all ductile metals can be burnished!

Proven quality

  • The burnishing process has been refined and improved  for over 100 years and has a proven record of success.
  • Monaghan Tooling Group and Elliott Tool Technologies continue this long tradition by providing the industry’s highest quality burnishing tools.
