product introduction
::LEANOMS
6 Inch High Air Pressure Drill Bit are specialized drilling tools used in various industries, including mining, quarrying, construction, geotechnical engineering, and well drilling. These button bits are designed to be attached to a 6-inch DTH hammer to create boreholes in the earth's subsurface.
History

Advantages Of 6 Inch High Air Pressure Drill Bit
1. While breaking rocks uses little energy, the single impact energy is substantial.
2. The piston and 6 6-inch high Air Pressure Drill Bit have a similar weight distribution that is long-lasting and efficient. Enhancing rock-crushing effectiveness will help the DTH Drilling hammer last longer.
3. The repeated crushing of rock is lessened by the center exhaust's effective slag discharge.
4. To drill holes in the water, the DTH Drilling hammer contains a check valve device.
5. When working, it is always at the opening of the hole, and the depth of the drilling has no bearing on how much impact energy is transmitted.
The large-diameter rock drilling sector enters the mechanized era with the invention of the DTH Drilling hammer. It increases drilling efficiency while also demonstrating the epochal advancement of rock drilling equipment. All, despite all of its benefits, it is still a tool for rock drilling. Maintaining a DTH Drilling hammer properly and promptly can increase its lifespan and significantly lower its cost of use, both of which are crucial for businesses.

Minimum requirements for air compressor capacity and pressure
The pressure and production rate of a DTH hammer is directly related to the air flow through the impactor. The pressure and performance of the impactor are closely related to the SCFM of the air flow provided by the air compressor. To determine the pressure required for the impactor (without water injection and good lubrication), the actual SCFM of the airflow delivered by the air compressor needs to be considered. Air compressors are rated by ACFM, which is equivalent to SCFM only at standard altitude and an inlet temperature of 60°F (16°). The SCFM of the air compressor output as the density of the inlet air increases or decreases with changes in temperature and altitude. As the density of the inlet air increases or decreases with changes in temperature and altitude, the SCFM output from the air compressor will also change. The pressure and performance of the DTH hammers are determined by the SCFM output from the compressor.

Operating hazards
LEANOMS
WARNING:
Avoid coming in contact with operating tools. Rock drilling tools in operation move with significant force. If you come in contact with an operating tool, you may be seriously injured.
Never grab or touch an operating tool. There is a risk of getting dragged into or caught by an operating rock drilling tool, which may cause serious injury. Avoid loose clothing and other items that may get caught. If you have long hair, cover it in a hair net.
CAUTION:
Rock drilling tools may become hot during operation, and remain hot for a period of time even after drilling has stopped. To avoid burns or other injuries, avoid direct skin contact with hot drilling rods.
DANGER:
• Compressed-air hoses between the compressor and the drill rig must be secured by means of an external or internal safety wire, which must be fastened safely to the drill rig. If the DTH hammer is to work at pressures above 10 bar (145 psi), any local regulations regarding air hoses and couplings must be strictly observed.
• Always check that hoses, hose nipples and hose clamps are not damaged, and that they are properly tightened and secured.
