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

  • Diamond 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.


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


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

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.

Operating Procedure

Diamond Burnishing – Stick Tool Style

The diamond burnishing tool is designed for use in lathes and similar machines. The tool should be mounted so that the diamond is perpendicular and on center to the surface being burnished.

Part Preparation: 100/120 RMS
Feed Rate: .003”/.004” (750 Max Surface Feet per Minute)
Coolant Required: Water soluble or oil

Can be used on most metals with a hardness below HRC40.

Diamond Burnishing – Boring Bar Style

The boring-bar style diamond burnishing tool is designed for lathes or similar turning machines to provide an improved surface finish on a manufactured part.

Part preparation: 100/120 RMS
Feed rate: .003”/.004” (750 Max Surface Feet per Minute)
Coolant required: Water soluble or oil
Maximum tool reach: 2.861”
Minimum hole diameter: .500”

Can be used on most metals with a hardness below HRC40.
