Product Information

Full details

The Lessmann Knot End Brush with Shank is designed for professionals needing to clean or prepare hard-to-reach areas. Its key benefit is the expanding knot design that opens up during rotation, allowing access to drilled holes and recesses. A potential caveat is the need for a compatible rotary tool to operate it.

FAQs

What is the primary use for this brush?

This brush is primarily used for cleaning, deburring, and surface preparation in hard-to-reach areas like drilled holes and recesses.

How does the brush open up?

The knot design of the brush causes the wire bristles to splay outwards due to centrifugal force when the brush is rotated at speed.

What type of wire is used?

The brush is made with 0.35 steel wire.

What size shank does it have?

It features a standard 6mm shank.

Can this brush be used on delicate materials?

Due to its steel wire construction, it is best suited for metal and harder materials. Use with caution on softer or more delicate surfaces.

What rotary tool speed is recommended?

Refer to your rotary tool's manual for recommended speeds when using accessories like wire brushes. Generally, higher speeds are needed for the brush to expand effectively, but always stay within the tool's safe operating limits.

Troubleshooting

Brush not expanding during rotation

Ensure the brush is rotating at an adequate speed. Lower speeds may not cause the knots to splay effectively. Check that the brush is not clogged with debris.

Brush wire breakage

Reduce excessive pressure against the workpiece. Ensure the tool is operating at a suitable RPM and that the brush is not damaged or worn out. Do not use for aggressive material removal.

Vibration or imbalance

Check that the brush is securely and centrally mounted in the tool's chuck. Ensure the rotary tool itself is functioning correctly.
