Product Description

Wholesale 254mm Numa100 Shank High Air Pressure DTH Hammer Drill Button Bit

Product Description

Down the hole(DTH) tools manufacturer KINGDRILLING supply DTH Drill Bits are available in a wide range of sizes and with a number of custom design features for optimum performance in a rock formation, which are designed to match all conceivable applications for water well industries, mining and construction. Numa's pneumatic lubrication are positive displacement, air-operated, lubrication systems. They are designed to inject rock drill oil into the air line under positive pressure to ensure the proper amount of oil is supplied to the DTH hammer while drilling.

DTH drill button bits are designed to deliver high penetration rates, precise hole straightness, and optimal rock fragmentation. The tungsten carbide buttons on the bit's face bear the brunt of the drilling forces, efficiently fracturing the rock formation and facilitating rapid advancement of the borehole.

The choice of DTH drill button bit is crucial and depends on factors such as rock hardness, abrasiveness, and the desired drilling depth. By selecting the right bit design and button configuration, drillers can enhance drilling efficiency, reduce downtime, and ultimately lower operational costs.

 

Technical date

How to choose the suitable head face of the DTH drill bit?
1. Concave:
Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.
2. Convex: 
Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.
3. Flat:        
Suitable for special hard formation stratum, especially for fracture, crack spacing and complex formation drilling effect is very good, has the good perpendicularity of the borehole.

Product Application

It is suitable for Geothermal well drilling, Water well drilling, Pipe roofing(umbrella arch drilling), Foundation work.
