Specifications

 
pneumatic D-T-H Drill is a kind of rigs that may drill larger hole-diameters, and enchased with a cemented carbide bit; it can obtain long depth in a single hole. MFDTHR is mainly used for bore-holes drilled by diamond wire saw, such as vertical and horizontal holes cross-linking in order to run through diamond
wire, as well as filling explosives to large rocks in mining, and peeling covered layers. Nowadays MFDTHDR
are used in stone mining the most to drill run-through holes which pass through diamond wire for sawing
stone work.
 
 Characteristics:
1.) Such models are normally multi-purpose machines which have the function of drilling vertical, horizontal, tilted those three kinds of holes (i.e. multi-functional).
2.) New models of the reducer, pneumatic-driven motor are circular shape designs which allow the rigs to
closely meet ground during level operation.
3.) Sliding shelf drilling system uses the skateboard-style for lifting, and uses high-sensitivity pneumatic
motor for chain-driving while giving pressure to rock drill for it to move. There is no damping device fitted, it
is hence suitable for operations under small spaces conditions.
4.) It is also equipped with drilling group frame to carrying out lateral movement in small spaces, complete
the adjustment of drilling anchor points, so that it has strong practicability.
5.) The chassis features four adjustable bolts which can adjust their heights in order to adopt different
operation environments; and also is configured with self-lockable nut to maintain the machine’s stability.
6.) It is usually configured with two different sizes of impactors which can be exchanged according to the
needs in order to adopt requirements according to different calibers.
7.) Air distribution system has its independent operating platform, can go through long-distance operations in order to prevent effects on health brought by dusts.
8.) Such models usually have water filtering devices; lubrication system is equipped with pressure gauge,
safety valve, together ensuring the rigs have enduring and normal functions.

Performance and Parameters:
Mainly used primary and secondary drilling in all stone quarries.
Available for vertical, horizontal and slant drilling.
It should be used for drilling before wire saw cutting.
