DRILL STEEL & BITS
Warranty Policy
All drill steel and bits sold to customer are
intended for use in drilling concrete. It is not
capable of drilling through steel mesh, rebar
or dowel bars. Use in these applications will
void all warranties and dramatically shorten
bit life. Bit life is also affected by the sharp-
ness of the bit, type of aggregate and con-
dition of concrete. Minnich Manufacturing’s
drill steel and bit warranty is limited to the
warranty provided by the supplier. All war-
ranty claims must be submitted to Minnich
for evaluation and sent to the supplier for
authorization.
