1. Pneumatic rock drilling machine includes: Y6, Y20, Y24, and Y26(hand held), YT24 and YT28(air leg).
This type rock drills use compressed air as power, mainly used in construction sites, various types of mines, tunnel, railways, water conservancy construction and national defense construction areas for drilling operations.
YT24 YT28 pusher leg rock drills always works with support air leg, can be used for any angle drilling.
Y6, Y20, Y24, and Y26 hand held rock drills works without air leg, mainly use for downwards drilling.
2. Gasoline rock drilling machine includes: YN27, YN27C and YN27J.
This type rock drill adapt to outside situations where there is no water, no electronic power and no air compressor. It's a kind of hand held rock drill with gasoline engine, air pump and rotation plumbum equipment for running or stop. It can be used for breaking, drilling, blasting, tamping splitting and ramming.
