Suggested Applications:
1) Medium duty asphalt and concrete milling.
2) Descaling steel decks.
3) Removing thick material build-ups of greases,
paints, oils, vegetable powders and resins from non-
wood type floors.
4) Dried, fully cured, carpet and tile adhesive removal.
5) Painted traffic line removal.

SERVICE LIFE 2. The beam flail should be replaced
when the outside diameter is worn to approximately 1-
5/16 inch or the inside diameter elongates to
approximately 3/4 inch.
Pentagonal Flail
The pentagonal flail is manufactured from high
carbon, alloy steel that is through hardened for
additional service life. FIGURE 4. Each section of the
five sided design features a small, tungsten carbide
insert that is first placed in a small hole and then held
in position with copper brazing. It is highly effective for
scabbling or scarifying and delivers medium to coarse
surface finish texture. Designed for high speed
material removal of the work surface.

Suggested Applications:
1) Heavy duty asphalt and concrete milling.
2) Milling concrete joints.
3) Asphalt and concrete grooving.
The pentagonal flail is designed for more aggressive
and rapid removal of a surface in comparison to the
beam flail. The addition of the tungsten carbide inserts
contributes to its long service life and higher
production rates. The tungsten carbide is also the
main reason for the cost differential between it and the
other flails. The design configuration yields a rather
coarse surface finish and texture. For many job
applications, this finish and texture will be satisfactory.
Some applications may require an additional
smoothing process. For example: removing high spots
or other irregularities from sidewalks. The initial
process would utilize pentagonal flails for productivity
and service life reasons. If the resulting surface finish
is too coarse to meet specifications, it can be
smoothed with the use of the star or beam flails.

SERVICE LIFE 10. The pentagonal flail should be
replaced when two successive tungsten carbide
inserts break off or the inside diameter elongates to
approximately 3/4 inch. In service, the flail body will
wear much faster than the tungsten carbide inserts.
The copper brazing used to weld the inserts into the
body can fail and an insert break off. The flail can still
be used in service. It will just wear a little faster and
more uneven in that particular area. As a general rule,
a pentagonal flail can be utilized until there has been
body wear that will no longer support the tungsten
carbide inserts.
Milling Flail
The milling flail is manufactured from high carbon,
alloy steel that is heat treated for additional service
life. FIGURE 5. Each section of the five sided design
features a rectangular, tungsten carbide insert that is
held in position with copper brazing. The milling flail is
primarily designed for "climb" milling applications.
This requires that the Floor Planer be pulled toward
the operator when being utilized. Removal rates are
dependent upon both surface and substrate material
composition.
