KINGDRILLING DTH taper drill bit description:

Taper cross X bits are tend to drill round holes in all rock conditions.The steel support in the narrow parts. X drill bits is smaller than 64 mm because of the restricted circumference.

Where straight hole accuracy is required in hard, abrasive ground, blade bits of cross bit and X-bit are ideal, as they tend to resist gauge wear better than button bits. Generally, blade bits are not as productive and yield higher drilling costs than button bits. In addition, blade bits generally require more frequent sharpening than button bits because of the less wear resistant carbide grades on the face.

Product application:

Tapered drill bits are used in granite and marble quarry, gold mine, railway, tunnel.

FAQ:

1. What is top hammer drilling?

In Top Hammer Drilling the hammer produces a percussive force on the drill rods or tubes, which is transmitted to the drill bit. The feed device is usually attached with a hinged boom to a mobile unit.

2. Is top hammer drilling vs down-the-hole drilling?

The primary difference between the top hammer and down-the-hole drilling methods is where the hammer is attached. The hammer in the industrial equipment makes contact with the bit during the down-the-hole drilling method. The top hammer drilling method's activity is concentrated at the very top of the drill string.

3. How does the Top Hammer Drilling work?

The percussive force of the top hammer drilling produced by the piston of the pump in the hydraulic drilling rig, it is transmitted to the drill bit via shank adaptor and drill pipe, This is the difference between DTH drilling. Meanwhile, the percussion system drives the drilling system rotation. When the stress wave reaches the drill bit, the energy is transmitted to the rock in the form of bit penetration. The combination of these functions enables drilling holes into the hard rock, and the air compressor only performs dust removal and slagging in top hammer drilling.

The combination of these functions enables drilling holes into the hard rock, and the air compressor only performs dust removal and slagging in top hammer drilling.

Impact energy multiplied by impact frequency together creates the percussive output of the drifter. However, usually, top hammer drilling used for hole diameter maximum 127mm, and hole depth less than 20M, which in high efficiency.

4.What is the general delivery time?

15 working days for DTH bits.

20-25 working days for DTH hammer

3-5 working days for ex stock items.

5. Competitive price:
