Power and Hand Tube Brush Selection Tips

The stems in power tube brushes are not as strong as the stems in most other brushes. Therefore, it is very

important to avoid any load conditions and brush speeds that can cause excessive stem deﬂ ections and

destructive bending.

A suggested guideline to avoid this unsafe condition is minimizing the overhang of the stem to under an inch,

and running the brush at speeds below 2,000 RPM.

Increasing overhang could decrease the safe speed at which the brush can operate. To reach into deeper holes,

use drill extension rods instead of increasing stem overhang.

Before Starting the Brush:

Tube Brush Operating Recommendations

Correct

Mounting

in Chuck

Incorrect

Mounting

in Chuck

• Secure brush in chuck

• Ensure clockwise brush rotation

(running the brush counter-clockwise

could cause the brush to fall apart.)

• Clamp work securely.

• Position all guards in place.

• Align brush with the work so the brush rotates on its

true centerline to prevent any stem deﬂ ections.

• Guide the brush into the hole before starting the

brush rotation.

• Always wear eye protection.

• A ﬂ at burrite style tube brush is most effectively used

with a holder on blind, threaded holes.

• A round tube brush is most effectively used fully chucked

on smooth or threaded blind holes.

• A single stem, single spiral tube brush is most effectively

used for manual or hand cleaning applications.

• A double stem, double spiral tube brush is most effectively

used with power tools for heavy-duty cleaning and deburring.

• A Polyﬂ ex

Encapsulated double stem, double spiral tube

brush is most effectively used on power tools for very

aggressive cleaning and deburring applications.
