IMPLEMENTATION GUIDES
Manual Deburring

Manual deburring is readily accomplished with ORBITOOLT deburring cutters mounted in electric hand grinders (air grinders are not recommended-the rpm's are too high). We offer the unit shown below, part number 30004.

The patented design of ORBITOOL cutters provides a distinct advantage over conventional burrs. With ORBITOOL cutters it is much easier to control the deburring. Conventional burrs will remove material anywhere they touch the surface of the workpiece. Accidental/unintended contact damages the workpiece resulting in scrap or rework. With ORBITOOL cutters material removal occurs ONLY at the edge of a workpiece - where the burrs are! The disk on the end of the cutter prevents the tool's cutting edges from contacting the surface of the workpiece until the tool encounters an edge. Once the disk passes over the edge, the cutting edges can contact the workpiece and remove material. Moving the head of the tool back and forth over an edge is how you deburr with ORBITOOL cutters.

Because of its unique design, the results obtainable with ORBITOOL cutters will be superior to other hand deburring methods. As with other manual methods though, the results still depend on the skill and attention of the operator.

Safety is of paramount concern when deburring manually with any rotating cutting tool. Spinning any tool, especially one with a flexible shaft, in an uncontrolled fashion at high speeds is inherently dangerous. A fundamental feature of ORBITOOL cutters is the flexible shaft. This feature can be extremely hazardous when the cutter is used improperly.

With ORBITOOL cutters control of 3 factors is critical to safe operation: speed (tool rpm), shaft length, and contact or "engagement" with the workpiece.

SPEED: It is difficult to provide exact safe speeds for each size cutter as there are several variables involved. In general, smaller cutters can be used safely at higher rpm's than larger cutters. With ORBITOOL cutters use the lowest rpm that provides acceptable results. Charts indicating generally safe speeds for each size cutter are provided below. NOTE: the charts provide guidelines only-the user assumes all responsibility for determining the safe cutting speed (rpm) for a given situation.

SHAFT LENGTH: In general, shorter cutters can be used at higher rpm's than longer cutters. With ORBITOOL cutters it strongly advised the shaft of the cutter be trimmed as short as possible while still permitting the tool head to reach the edge to be deburred. NOTE: the user assumes all responsibility for determining the optimum safe length of cutter for a given situation.

CONTACT or WORKPIECE ENGAGEMENT: With ORBITOOL cutters it strongly advised that if the tool is spinning, the head of the cutter should be in contact with the workpiece. When deburring internal features though, it is generally sufficient that the head of the tool be fully inserted into the opening before the tool is spun.

FAILURE TO OBSERVE THESE PRECAUTIONS MAY RESULT IN CATASTROPHIC FAILURE OF THE ORBITOOL DEBURRING TOOL, RESULTING IN POSSIBLE INJURY TO THE OPERATOR AND BYSTANDERS, AS WELL AS DAMAGE TO THE WORKPIECE AND EQUIPMENT IN THE AREA.
All other customary precautions associated with using cutting tools in powered hand tools must be observed as well. These precautions include, but are not limited to: use of guards, safety apparel (eye wear, face shields, hair nets, etc.), electrical safety, etc. SAFE AND PROPER USE OF ORBITOOL DEBURRING TOOLS IS THE RESPONSIBILITY OF THE USER.
