Characteristics of Quick Change Bars:
1、High quality carbide and brazing technology ensure excellent abrasive and impact resistance.
2、Cutting geometry is unaffected after holder replacement.
3、Tool and carbide are designed to different shapes for inner and outer overcut.
4、High joint strength between tool and holder due to internal guide.
Welding Bars
They are on the cutting ring of drill casing or coring barrel for piled retaining wall construction. All types of rocks and concrete can be drilled through by using appropriate block.
Characteristics of Weld-on Blocks:
1、High strength.
2、Self-cleaning
3、Protected body by distributed carbides.
