The hand hold rock drill is used for rock drilling, blasting holes and other drilling works in the quarries, small coal mines and other constructions. It’s suitable for drilling of horizontal or inclined holes on the medium-hard and hard rock. When it’s matched with air leg Model FT100, it can blast holes from different directions and angles.
Blast hole diameter is between 32 mm and 42mm. with an efficient depth from 1.5m to 6m. It’s recommended to be matched with Model W1.8/5 air compressor which is powered by Model S1100 diesel engine. Other suitable air compressors can also be matched with this rock drill.
1. YO18,Y19A,YO20,Y24,Y26 are Hand Held Jack hammer.
2. YT23,YT24,YT26,YT27,YT28,YT29A,MZ7665 are Air leg Jack hammer
This type Jack hammer 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.Suitable for either drilling downward or incline of blast holes in medium-hard rock, of for second blasting operation,Centrally grouped control, nimble starting, stable running and easy maintenance.
YO18,Y19A,YO20,Y24,Y26 hand held jack hammer works without air leg, mainly use for downwards drilling.
YT23,YT24,YT26,YT27,YT28,YT29A,MZ7665 pusher air leg jack hammer always works with support air leg, can be used for any angle drilling.
