Geothermal Drilling Tapered Button Bits Hard Rock Drill Bits Tungsten Carbide And Alloy Steels

Specification of HD35 DTH Bits:

Bit Face Shape of HD35 DTH Bits:

1. Drop Center Face

For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.

2. Concave Face

The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.

3. Convex Face

For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.

4. Double Gauge Face

This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.

5. Flat Face

This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.

Carbide Button Shape of HD35 DTH Bits:

1. Domed/ Round Button

It is usually used as gauge buttons of DTH bits, suitable for very abrasive and very hard formations.

2. Parabolic/ Semi-ballistic Button

It is usually used as gauge buttons and front buttons of DTH bits, suitable for medium abrasive and hard formation

3. Ballistic Button

It is usually used as front buttons of DTH bits, suitable for medium abrasive and medium hard formations. It can also be used as gauge buttons if the rock is soft.

4. Sharp Button

It is usually used as front buttons of DTH bits, suitable for soft formations where fast penetration rates are possible.

5. Flat Button

It is usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits.
