What is a ball-shaped carbide burr used for?
A ball burr is particularly useful for hollowing, carving concave surfaces and creating rounded grooves or recesses. It can also be used for smoothing curved edges, shaping contours and removing material from difficult-to-reach areas.
Double-cut flutes
The crossed cutting flutes break the removed material into smaller chips, helping the burr cut efficiently while offering good control. Double-cut burrs generally produce a more manageable finish than single-cut burrs and are well suited to detailed shaping and material removal.
Suitable materials
Suitable for use on a wide range of materials, including steel, stainless steel, cast iron, non-ferrous metals, wood and plastics.
Will it fit my rotary tool?
This burr has a 2.35mm (3/32") shank. Check that your rotary tool, flexible shaft or micromotor has a suitable 2.35mm collet or adjustable chuck.
For compatible Dremel tools, the Dremel 4486 Multi-Chuck can be used to hold a 2.35mm shank.
How to use
Secure the burr firmly in the tool, leaving as little unsupported shank as practical. Begin at a moderate speed and allow the carbide teeth to do the cutting without applying excessive pressure.
Keep the burr moving across the workpiece to prevent it from digging into one area. Use appropriate eye protection and do not exceed 35,000 RPM.
