Cobra™ Drill Bits (Wet and Dry)

The Cobra™ drill bits are engineered to drill through reinforced concrete with or without water.These bits are available in 6 or 10 inch (15.24- 25.4 cm.) drilling depths and range in diameter from 1 to 5 inches (25 to 127 mm.).

Standard MQ Drill Bits (Wet)

This core drill can use the following series of wet drilling bits:

■GCB Series – economy quality small jobs.

■GB Series – standard quality small to mid-size jobs.

■PRB Series – premium quality for fast speeds.

■PCB Series – super premimum quality and long life.

■PCB Series – pro quality, high steel content and extremely hard aggregate small jobs.

Threads/Adapters and Core Bit Combinations

Figure 1 and Table 1 depict most Adapter/Core Bit combinations and part numbers. The CDM1H is manufactured with an 18mm male drive end that directly connects to all MQ COBRA™ drill bits. For other US standard threading options, the CDM1H includes two adapters: (1) ADM1858 – that permits connection of 5/8”-11 female threaded bits, and (2) ADM181147 – that permits connection of 1 ¼”-7 female threaded bits.
