Basic Guidelines:
Quick Set Up of the Orbitool*: The shaft of the cutter can be easily trimmed to the required length. This will reduce vibration and improve operators ability to control the process. Tighten the shaft of the cutter and the drive pin in the flexible holder.
Step 1: Position the tool on the axis of the hole directly above the entrance to the part.
Do NOT begin rotation of the tool yet.
Step 2: Move the tool inside the hole to a depth close to the intersection to be deburred.
Step 3: Move tool to the side of the hole until the axis of the tool is located at the diameter of interpolation.
Step 4: Begin rotation of the tool. Begin helical interpolation.
The direction of interpolation and the direction of the tool rotation must coincide.
Step 5: Advance tool to the center of the second hole. Stop rotation and interpolation of the tool.
Step 6: Move the tool to the center of the bore.
Step 7: Withdraw tool
Tip: Excessive dwelling and too slow of a feed rate can lead to disproportionate material removal and creation of chamfer.
RPM:
The tool is rotated in a clockwise direction. The faster you spin the shaft, the faster you remove material. The RPM limiting factors are the machine spindle rpm and the desired surface finish. Suggested RPM for the Orbitool* is 2,000 to 12,000 rpm. A slower rpm results in a lower vibration and a better finish can be expected. Note that harder materials typically require a fast rpm.
Feed Rate (Z Axis):
Feed rate is responsible for the amount of material removal as well as the shape of the radius at the intersection that is being created. On softer materials such as aluminum, slow feed rates will result in chamfer creation instead of the radius at the intersection. Feed rates of 0.002 to 0.025 inches per one circular interpolation are recommended.

Orbitool Deburring Tool Guidelines (clicking this link will take you to a .pdf page. Once there use your back button to return to this Toolinghouse page)
Feel free to experiment beyond the general guidelines shown in the link above but never compromise safety.
Safety First: Never spin the Orbitool Deburring Tool before inserting the cutter into the bore of the part. Spinning the tool outside of the part may result in the separation of the cutter and injury to the operator.
The Orbitool is a relatively new and unique cross hole carbide
deburring tool. As with any new technology it will take the user a few
tries to fully utilize the tools potential. Once the operator has run
a few deburring operations with the Orbitool the time for deburring
will decrease and the quality of deburring will increase.
