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

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.

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
