CIR shank low air pressure DTH hammer details:
We manufacture DTH Hammers including low air pressure CIR hammer
and high air pressure dth hammer in different size. These hammers
are made corresponding to drilling bits to carry out prevalent
objectives. These hammers are used in various down the hole
operations like bench Drilling. CIR series DTH hammer, a kind of
valve-equipped low air pressure hammer with a single piston, a
plate valve and a central exhaust structure. The compressed air is
adopted as the driving force. To prevent dust pollution and get a
better performance, some high pressure water may be added into the
air for the wet rock drilling.

FAQ:
1. What is DTH hammer?
Down-the-hole drilling (DTH) essentially involves a drilling hammer
at the bottom of a drill string. It relies on three elements for
drilling holes: bit loading (weight), rotation and air. These
active elements combine to be efficient at crushing rock.
2. What are mining drill bits made of?
The drill bit, which is located at the tip of the drillstring,
below the drill collar and the drill pipe, is a rotating apparatus
that usually consists of two or three cones made of the hardest
materials (usually steel, tungsten carbide, and/or synthetic or
natural diamonds) and sharp teeth that cut into the rock.
3. How does DTH drilling work?
A down-the-hole drill, usually called DTH by most professionals, is
basically a jackhammer screwed on the bottom of a drill string. The
fast hammer action breaks hard rock into small cuttings and dust
that are evacuated by a fluid (air, water or drilling mud).
