| Blue Demon replaceable blade bits are
effective and efficient all-purpose, blade-type bits for shot hole, exploration, slim hole, blast hole, and water
well drilling. The four bit bodies, providing a complete range
of sizes from 17/8" (47.6mm) through
24" (609.6mm), use low cost
expendable blades which are designed to be completely
worn out and thrown away.
Available in Series MP-200, DB-400,
AC-600,
and SH-800 sizes, these bit
bodies become a permanent part of the drilling equipment
and are used with many sets of long-lasting replaceable bit blades.
|
| Replacement blades are changeable in any
fractional size within the range of each bit body (normally 1/8
inch). A
complete assembly consists of tool joint connector,
optional reaming stabilizer, locking bowl, bit shank, and
a set of replaceable bit
blades.
All Blue Demon bit parts in the same
series are interchangeable, allowing any part to be
replaced as it becomes worn. Each assembled bit may be
used with or without reamers (reaming stabilizers cannot
be used when using connectors having breakout lugs), as
dictated by drilling conditions.
|
All Blue Demon
bits are designed for use with air, water, or mud. Connectors
are available, threaded with box or pin connection, to
fit directly on any common drill rod used with portable
drilling equipment. Used in conjunction with shank and
locking bowl to complete assembly.
