YT28 Portable Pneumatic Rock Drilling Tools Drills With Air Leg

Product Information:



1. The YT28 air-legged rock drills are equipped with air-water linkage, quick
return of the air-leg and air pressure adjustment. The control handle is
centralised in the shank, which is novel and easy to operate. The sound-deadening
cover can effectively reduce the noise and change the exhaust direction at will,
improving the working conditions on site. Compared with the same type of rock
drills: light weight, low noise, high efficiency and good economic effect.

2. The machine can be used for wet drilling of medium or hard rock with a diameter
of 34-42 mm and a drilling depth of up to 5 m. It can be used with the FT160A air
leg to drill horizontal and inclined holes; it can also be mounted on a trolley or
stand.
