Carbide Drilling Tools DTH Button Drill Bits For Mining Tools Forging Energy & Mining

Production Description

Carbide inserts are replaceable and usually used in machining steels, cast iron, high-temperature alloys, and nonferrous materials. Carbide inserts allow faster machining and leave better finishes on metal parts. Carbide inserts can withstand higher temperatures than high-speed steel tools.

The life of the DTH bit depends on the material and technology of the bit. The ANBIT bit is made of the most efficient high-quality alloy steel.
Use quality forged steel, heat treatment, and shot peening to provide a durable and reliable balance of strength and toughness.
1. Long life of bit: alloy steel material has a long service life, which is higher than similar products;
2. High drilling efficiency: the drill teeth are wear-resistant so that the drill bit can always be sharp, thus greatly improving the entering speed of the teeth;
3. Steady drilling speed: the drill bit breaks the rock by scraping and cutting;

How to Select Threaded Button Bits Face shape and Carbide Button Shape



Drop Center

For high penetration rates in soft to medium-hard and fissured rock formations.
Concave Face
The all-round application bit face specifically for a medium-hard and homogeneous rock formation. Good hole deviation control and good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistant to steel wash, and good resistance to steel wash step gauge bit.
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 and resistance to steel wash.


B: Insert Carbide Button shape Selection
The different button is ideal for different ground conditions, abrasive levels, and penetration levels. In general, the more gauge buttons, the better over performance, especially in hard rock.

Spherical
* Application Strength-multipurpose
* Best suited to soft abrasive
* 25,000 to 45,000 PSI (170 to 300 MPa)
* Abrasive to very abrasive

Ballistic Button
* Application Strength- fast penetration
* Best suited to soft ground
* 10,000to 20,000 PSI(70 to 140 MPa)
* Nonabrasive ground

Semi-ballistic
* Application Strength-fast penetration
* Best suited to medium ground
* 15,000 to 25,000 PSI(100 to 170 MPs)
* Mildly abrasive ground

Wedged (Conical) Button
* Application Strength- fast penetration
* Suited for all non-abrasive ground types
* Smaller contact area
* Best suited for smaller diameter bits


Features of our Threaded Button Bits:
* Be produced from premium quality Nickel-alloy steel or Molybdenum-ally steel for increased durability and wear characteristics
* Specific heat treatment standards and strict production process ensure consistent performance
