Diamond burnishing tools for internal use are non-intrinsic tools for smoothening and work hardening of holes and contours.

Advantages

Simple to use
Compact design available for machines with limited tool space
Can be adapted to all materials by means of four spring elements (included in delivery)
Diamond radii from 0.4–5 mm available
Diamond indexed for multiple machining
Highest surface quality and hardening
Universally applicable
Ideal for contour machining
For hard machining and thin-walled workpieces
Tolerance compensation through spring-loaded design
Changeable diamond insert
Re-grinding of the diamond is possible
Cost-effective/ low investment
