Huada's CBM80/180 range is a water-cooled core-boring machine for stone drilling and sampling. The three listed variants are not simply different motor sizes: their hole diameter, maximum depth and feed range define different jobs.
Choose from the required hole
| Model | Hole diameter | Maximum depth | Feed rate |
|---|---|---|---|
| CBM80-15HA | Ø80 mm | 40 m | 2–5 m/h |
| CBM80-22HB | Ø80 mm | 80 m | 4–7 m/h |
| CBM180-22HB | Ø180 mm | 20 m | 2–4 m/h |
The CBM80-22HB extends the listed Ø80 mm drilling depth, while the CBM180-22HB changes the hole diameter to Ø180 mm and has a shorter maximum depth. This distinction should be checked before comparing motor power.
Features relevant to setup
The source describes a compact layout intended for lifting into narrow spaces. Double-inverter control is used to adjust feed as stone hardness changes, with hole straightness as the stated objective. Water cooling at the tool bit is intended to control dust and noise. End-of-stroke stoppers are optional and should be identified in the order if they are needed.
For a deep hole, access for adding and removing drill sections is as important as the footprint of the power unit. The mounting proposal should show that working space and the route used to lift the machine into position.
