SERIES MP-200
Blade Sizes 1⅞” (47.6mm) through 3¼” (82.5mm) for use with air, water or mud
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 1⅞” (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.
