Blue Demon - Model Series MP-200 -Drilling Blade

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.
