SD Button Bits

We are engaged in manufacturing supplying and exporting high quality DTH Button Bits. These Button bits have two flushing holes and are available in three flavors: Flat, Convex and Concave. These Down The Hole (DTH) bits fit the most popular DTH hammers use in water welling, mining, construction and quarrying. We offer a wide assortment of DTH button bits that works with precision and provide accuracy while penetrating into the sub-soil formation of varied nature.

The DTH Button Bits are also called rock busters due its high strength, wear and tear resistance. Our flawless range of DTH Button Bits is appreciated for durability, dimensional accuracy, high performance and corrosion resistance. We are capable of offering a wide range of DTH Button Bits that is well known for its efficiency during drilling, high penetration rate, good flushing and long service life has made our product favorite world wide. Our DTH button bits are manufactured from the optimum quality raw materials using high technology machines.

DTH Button Bits:


Features:

Button bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 MPa to 260 MPa compressive strength). Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture.

Recommended for eliminating hole deviation

Widely used drifting and tunneling

Bit face design is ideal for medium-hard to hard abrasive rock

Bit face shape selection:

1. Drop Center Bit

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. Flat Face Bit

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.

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. 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.
