Description

The YT27 air-legged rock drill is a highly efficient lightweight rock drill suitable for downward or inclined drilling in medium-hard or hard (f=8 - 18) rock with a diameter of 34 - 45 mm and an effective drilling depth of up to 5 m.

 

Product Features:


1、The YT27 air leg rock drill has the features of strong function of blowing and cleaning the gun hole and high torque of turning to braze
2、In addition to the advantages of the YT27 air-legged rock drill, it also adopts the flange control valve to produce gas and other functions.
3、The YT27 air-legged rock drills are most suitable for rock drilling in large mines and roadway projects.
