SERIES MP-200
Blade Sized 17/8"
(47.6mm) through 3¼" (82.5mm) for use with air, water or
mud
The Type MP-200 bit was developed specifically for mineral
exploration, coal test, foundation test and grout hole drilling.
Also commonly used for drilling inside small diameter tubing in
both the oil and water well industries.
The MP-200 Series bits are designed for use on lightweight
drilling equipment. The Rock Cutter Blades perform best in soft
formations. The carbide Insert Blades are designed for use in
medium-hard formations that are stronger than those drilled by
the Rock Cutter type.
These bits are available in the 3-blade Insert type or the
3-blade Rock Cutter type.
Stocks are regularly maintained in common sizes corresponding
to diamond drill specifications, with the AX size ground to 17/8"
(47.6mm), BX to 211/32" (59.5mm), and
the NX to 231/ 32" (75.4mm). These
bits are used to drill inside standard diamond drill casing and
should be ordered by the letter designation.
