Frequently Asked Questions

The Difference

Each fine alumina fiber rod is made by binding together 1000 alumina fiber filaments (ALF), each only several µm in diameter. The tips are the actual cutting edges so there is no damage to the peripheral area of the part.

Self-sharpening tips lead to superior grinding performance. End-to-end solid abrasive rod material assures consistent performance. Unlike brass wire, steel wire and abrasive impregnated nylon brush filaments, the unique design of the XEBEC® fiber rod allows it to maintain its shape with no deformation even after repeated use. This leads to consistent performance time after time.

FAQs

What is the largest burr size? up to 1.0 mm with the blue brush.

Does it deform the work piece or change part dimensions? Not if used correctly. The white or blue brush can remove tool marks if desired.

What kind of material will this work on? Anything from plastic to High-Temp alloys.

Does it work on hardened material? Yes, up to 57 Rc.

With or without coolant? Coolant isn’t required but will help improve surface finish
and tool life.

Pressure? Pressure is a variable of the depth of cut, more depth of cut will result in more
aggressive deburring and surface finishing.

How much pressure should I put on the brush? Depth of cut should range from .020 to .060 (0.5 to 1.5mm). Do not place excessive load or force on the brush. Use of the floating holder is highly recommended for most consistent performance and optimal tool life.

How do I adjust the brush for wear or tool pressure? As the brush wears and the fiber length decreases, use the set screws in the sleeve to adjust the fiber projection to the optimal length. In addition to adjusting depth of cut, a shorter bristle projection from the holder will result in more aggressive deburring action.


What is the purpose of the sleeve? The sleeve serves as a holder for the cutting fiber brush and allows the exposed length of the fiber rods to be adjusted in order to achieve optimal grinding performance. A shorter projection will result in more aggressive grinding action where as a longer length will provide greater flexibility of the cutting fibers.

How do I run it? The preferred method is CNC equipment. Any machine tool and some hand tools are usable.

What is the best method to hold the brush? Collet chucks are the preferred method of
holding the sleeve shank.

Can I run it on a powered hand drill? Yes, but depth control and horizontal orientation cannot be regulated, resulting in premature tool life.

How many RPMs do I need for cross-hole deburring brushes? Minimum of 15,000 on the 1.5mm brush. Minimum of 8,000 on all others.

Does the orientation of the tool to the burr matter? Yes. It is best for the brush cutter path to be in the opposite direction of the cutting tool that created the burr.

Can you surface finish with a cutting fiber brush? Yes.

When do I begin to spin the cross-hole deburring brush? Never rotate cross-hole deburring brush outside of hole. The fibers will break and could cause injury to the o perator. See page 7 for more information.

Can I use this cross-hole deburring brush in a power tool? Yes, but depth control and horizontal orientation cannot be regulated, resulting in premature tool life.

What makes the XEBEC® cross hole deburring stones better than other stones? They are self sharpening and have consistent grain structure. In addition they deburr cross holes that are often not accessible with other tools.

Can these be used my hand or better suited in a machine? They work well on both applications.

What’s the difference between colors? Blue is the stiffest and most aggressive, followed by white, red and then pink.

Is there cutting action on all sides of the fiber brush? No, only the tips of the brushes cut. The entire surface of deburring stones have cutting action.
