Kitzel Commutator Tool Geometry (Drawing)
Kitzel “Top of the Line” Commutator Skiving Tools (Drawing)
Our “Top of the Line” Commutator Tool is an original Kitzel design. No other toolmaker can match this tool.
Features:
- Cleans the slots of the commutator with drag over
- Gives a uniform cut with minimum working pressure
- Combination of shear type action and skiving cut
- Non-interrupted cut reduces shock on the diamond because the diamond is engaged across the bars
- Large included angle for strength and long life of the tool

Diamond Tool Set-Up and Machining Parameters
- The tool should be setup with the cutting edge of the tool at the centerline of the commutator to be turned. Conventional commutator turning lathes are generally set for the tool to run at a height of .156”.
- Before installing the tool, be sure to remove any copper chips from inside the tool holder. The length is tightly controlled on all Kitzel tools both new and repaired. The tool should be installed perpendicular to the face of the commutator and secured tightly with the holder set screws.
- A synthetic diamond tool should remove between .005” and .010” of stock per side of the commutator. For lighter cuts a natural diamond tool may be considered.
- A commutator is best machined at 800 to1200 SFPM (Surface Feet Per Minute).
- A good starting feed rate is .005” IPR (Inches Per Revolution). The commutator surface finish can be controlled by speeding up or slowing down the feed rate.
- To ensure maximum diamond tool life, your lathe should be inspected and maintained regularly. Special care should be given to the journal bearings, end stops and drive belt.
