utilized for the final finishing sequence. Generally
speaking, the more aggressive the flail
configurations, the more coarse the resulting finish
and texture.
Many flail configurations are available to meet a
wide variety of job applications and surface material
specifications. To give additional perspective to each
configuration, a rating system of 1 to 10 (10 being
highest) has been devised.

Star Flail
The star flail is manufactured from high carbon steel
that is through ha
rdened for additional service life. It
is highly effective for light cleaning or scarifying and
delivers a finer surface finish texture. FIGURE 7.
Suggested Applications:
1) Removal of thin coatings and encrusted
accumulations.
2) Cleaning concrete and asphaltic surfaces
3) Removing thick material build-ups of greases,
paints, oils, vegetable powders and some resins
from floors.
4) Light scarifying prior to the application of
coatings, toppings or sealers.

SERVICE LIFE 1
The star 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.
Beam Flail
The beam type flail is manufactured from high
carbon steel that is through hardened for additional
service life. It is highly effective for scabbling or
scarifying and delivers medium to coarse surface
finish texture. FIGURE 8.

Suggested Applications:
1) Medium duty asphalt and concrete scarifying.
2) Descaling steel decks.
3) Removing thick material build-ups of grea
ses,
paints, oils, vegetable powders and some resins
from floors.
4) Dried, fully cured, carpet a nd tile adhesive
removal.
