Suggested Applications: 
1) Removing synthetic coatings, thermoplastic  and 
cold plastic marking  and lines from concrete and 
asphaltic surfaces.

PRODUCTIVITY 7 
SERVICE LIFE 7. Milling flails are designed to remove 
a  variety of traffic line materials from concrete and 
asphaltic type surfaces. With proper techniques, 
minimal  amounts of parent work surface material will 
also be removed during the planing process. Milling 
flails  are expensive. To realize maximum service life, 
milling flails should not be utilized for the direct 
removal of concrete and  asphaltic work surface 
materials.  Such use will drastically reduce their 
service life and substantially increase project costs. 
 
SPACER WASHERS. 
 
Spacer washers  are stamped from high carbon,  alloy 
steel that is heat treated for additional service life.

The Function of Spacer Washers 
1) Reduce the number of flails required to be mounted 
on the flail drum, thus reducing purchase  and 
operational costs. 
 
2) Arrange the flails in a sequence or pattern that 
minimizes "blind" or "open" spots created by the 
additional support plates of the two section flail drum. 
Always insert at least one spacer washer between two 
(2) consecutive flails. The exception to this rule is a 
configuration where its design does not require the 
use of spacer washers. A flail drum set up with only 
star, beam or pentagonal flails and no spacer washers 
will not penetrate the work surface  at satisfactory 
rates. Typical configurations minimize the hammering 
or impact action of the flails. However, this can also be 
useful when removing traffic lines. 
 

 
 
3) Allow the flails to be arranged on the one section 
flail drum in configurations of specific widths for many 
job  applications.  An example would be the use of 
pentagonal flails to groove a concrete floor. The 
spacer washers  are used to position the pentagonal 
flails at the desired width. FIGURE 7. 
 
Variances in material thickness and manufacturing 
processes can  affect the final thickness of both flails 
and spacer washers. Because of this occurrence, trial 
and error is important for assembling flails and spacer 
washers on a flail drum. By mixing and matching flails 
and spacer washers of specific thicknesses, the 
required number of components can be assembled on 
a flail drum in a minimum amount of time. 
 

 

USE ONLY FACTORY SUPPLIED SPACER 
WASHERS ON THE FLAIL DRUM. OTHER 
WASHER TYPES AND/OR CONFIGURATIONS CAN 
PRODUCE ABNORMAL WEAR AND ELONGATION, 
RESULTING IN COMPLETE SEPARATION FROM 
THE FLAIL DRUM. SPACER WASHER 
SEPARATION CAN RESULT IN PROPERTY LOSS 
AND/OR PERSONAL INJURY.

FLAIL DRUM RODS 
Flail drum rods are manufactured from 1/2 inch 
diameter  alloy steel. They are heat treated in a two 
step process that yields a surface hardness that 
resists wear and extends service life.  
Drum rod service life is difficult to predict because of 
the large number of flail configurations  and work 
surface materials. Normal wear should be uniform 
about the rod circumference. FIGURE 8.
