The small symbols represent a cross section of a twisted brush.
Single Spiral/Single Stem (2 wire)
Brush bristles are twisted between two stem
wires with a single wire on each side.
Double Spiral/Double Stem (4 wire)
Brush bristles are twisted between four stem wries with two layers of bristle. Each layer is perpendicular to the other
with a single stem wire in each quadrant.
Single Spiral/Double Stem (4 wire)
Brush bristles are twisted between four stem
wires with two stem wires on each side.

Technical Information
A popular layman’s term often used to describe any and all types of filament. Bristle is the hair of a hog and has been
used in brushes for centuries, resulting in the popular use of the term. The hair has a natural taper from the foot to the
tip end. The tip end has a natural split, which is called the flag.
Hair from the horse’s mane which is relatively soft or hair from the tail which is somewhat stiffer.
Vegetable fiber processed from the Mexican Argava Lechuguilla cactus. The natural fiber is absorbent and has a slight
abrasiveness. Tampico comes in different grades, colors and finishes.
Processed from the leaf stalks of the India Palmyra palm. Palmyra is absorbent and somewhat stiff.

Natural Brush Filaments
Synthetic Brush Filaments
Wire Brush Filaments
A wide variety of man-made synthetics are available and used in brush construction. Synthetic filaments are available in many
different shapes, colors and sizes. The more common sizes run from .005” up to .080” in diameter. Listed below are some of the more
common materials:
Highest quality, excellent abrasion resistance and bend recovery.
Excellent quality, most commonly used, good wet stiffness.
Nylon impregnated with silicon carbide or aluminum oxide grit.
Very durable filament with many of the same characteristics as nylon.
Lower cost than nylon, inert to most acids and chemicals.
Economical, durable, flaggable, and low heat resistant.
NylonType 6.12
Nylon Type 6.6
Abrasive Nylon
Schaefer Brush specializes in building twisted in wire brushes and utilizing wire filaments. We offer a wide selection of wire filled brushes to
accomplish any task. Some of the popular wire filaments are listed below:
Highly corrosion resistant, durable and preferred where contamination is a concern. The cleaning action of the
brush takes place at the tip or end of the filament. If carbon steel wire is used, the particles of carbon can corrode or
contaminate the surface being cleaned.
Very dark, hard, straight and wear résistance wire with good memory.
A soft non-corrosive wire less tendency to scratch.
A softer non-corrosive wire usually used in non-sparking applications.
A wave that is put in wire or synthetic filament. The crimp may vary in height and in number of crimps per inch
depending on the specifications we designate.
A process of splitting the ends of synthetic filament to product a soft tip or flag similar to that found on natural
hogs bristle.

The Schaefer Brush Warranty
We warrant all of our products to be free from defects in material and workmanship. Our liability is limited to replacing any product
proven defective.
Using Twisted Wire Brushes
When using twisted brushes with wire bristles, rotate the brush as if
tightening the brush construction. Most of Schaefer brushes are made
to be rotated clockwise when the brush points away from the user.
Safety Equipment & Requirements
Safety goggles or face shields must be worn by
operators or personnel in the working area of wire
brushes. Appropriate protective clothing and equip-
ment must be used where a possibility of injury exists.
Keep all machine guards in place.
Observe all speed restrictions indicated on brushes, containers,
labels, or printed literature. “MSFS” means “Maximum Safe Free
Speed” (RPM); that is, spinning free with no work applied. For
safety purposes, never exceed “MSFS”. Consult our office or repre-
sentative for maximum safe speeds pertaining to your application.
Listed in approximate pounds per pack (for freight calculations).
Brush Pressure
Remember, it is the tips of the wire filament that do the work.
Excessive pressure bends the filament. This results in excessive
flexing, which causes premature breakage and reduces brush life.
