Mining conical rock tooth drill bit

The button bit has higher technical content, longer drilling time and higher drilling efficiency. button bit has large bearing capacity, good wear resistance and fast drilling speed. According to the different carbide teeth, the tooth shape can be divided into hemispherical, conical and parabolic buckles and other types.
It is made of high-quality steel raw materials through quenching and tempering treatment to improve the hardness and toughness of the product. It is widely used in granite and marble quarries, gold mines, railways, tunnels, etc., suitable for fixed (short hole) and blasting drilling systems. High cost performance. The diameter of the drill bit ranges from 24mm to 60mm, and the taper is 4, 6, 7, 11, and 12 degrees. The delivery is timely, and the design, product quantity and button quantity can be delivered according to customer requirements.

Thread Button Bit

HOW TO CHOOSE A STYLE

Normal drill bit

Suitable for ordinary rock, hardness 8-14, abrasive rock. The main appearance is flat type, tooth diameter is moderate, alloy impact resistance and wear resistance balance, multi-choice high-ball teeth and semi-ballistic teeth, generally adapted to a variety of rocks, for the general rock and unclear rock type of the case are recommended.


Soft rock drill bit

Mainly applicable to non-breaking, hardness of 8 or less, non-abrasive rock. The main appearance is concave, tooth diameter is small, alloy impact resistance and wear resistance is better, more selection of semi-ballistic teeth, ballistic teeth, powder intensifying effect is better than ordinary type, in order to improve work efficiency.

Hard rock drill bit

Mainly used in F14 and above, non-abrasive rocks. The main performance is a large profile, tooth-shaped multi-choice ball teeth and high-ball teeth, alloy wear resistance, and impact resistance are better, powder ginger effect is slightly lower than an ordinary drill bit. Because the amount of alloy is more, the price is higher than that of the normal type.

Retrac drill bit

Mainly used in the rock relatively broken, rock layer changes in the construction, the main appearance of concave band tail design, conducive to unexpected situations in the back of the brazing, front-end style can be selected by reference to the above product design.

Thread Button Bit

HOW TO SELECT A PROFILE?

Parabolic button

Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.

Ballistic button

The high tooth height, mainly used in soft rock and ordinary rock F12 below, the speed of entry is fast, but the hard rock, very hard rock is prone to the phenomenon of broken teeth.

Hemispherical button

The tooth height is low, mainly used in extremely hard rock F14 or above, improves wear resistance, prevents the appearance of broken teeth, and the speed is lower.


DTH Drill Bit

BIT FACE SHAPE SELECTION

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.

Concave face

The all-around application bit face is specifically for medium hard and homogeneous rock formations. Good hole deviation control and good Flushing capacity.


Convex face

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

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.

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 and resistance to steel wash.




DTH Drill Bit

CARBIDE BUTTON SHAPE SELECTION


Domed/Round button

Domed/Round Button are usually used as gauge buttons of DTH Bits, suitable for very abrasive and very hard formations.

Parabolic button

Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.

Ballistic button

Ballistic Buttons are usually used as front buttons of DTH Bits, suitable for medium abrasive and medium hard formations. They can also be used as gauge buttons if the rock is soft.

Sharp button

Sharp Buttons are usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible and button breakage is minimal.

Flat button

Flat buttons are usually used as protection buttons to reduce wear on rubbing surfaces of DTH Bits.
