Low Air Pressure Tungsten Carbide DTH Hammer Bits 4 5 6 7 8 Inch For Metal Drilling
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
We select best steels from Sweden Ovako factory or Baogang, the Tungsten carbide inserts are selected YK05 with hot insert technology.
DTH Hammer drill bits are normally used on limestone,Granite, bluestone etc. YK05 button inserts can let the drill bits bear any hardness rocks. Special design to improve the drilling efficiency.
DTH Hammer bit is also called DTH BIT, DTH Button Bit, Down The Hole Button Bit, Rock Bit, Rock Drill Bit,
Low Air Pressure DTH Button Bit, High Air Pressure DTH Button Bit
Button bits should be reground when penetration rates drop or if the cemented carbide shows signs of damage Fixed grinding routines often result in good working practices.Bits for instance, can be examined and then reground after a specific number of holes, or at the end of the shift. Premature grinding is not necessarily uneconomical since less carbide needs to be ground off.
It is better to regrind rather than reducing productivity due to damage.Correct grinding adds considerably to drill bit service life. But equally important, it also enhances the performance of the entire drilling operation, especially hole straightness.
Generally Our DTH hammer bits matches most top class brands as Atlas Copco, Sandvik, Furukawa etc drill rig.
The connection have two different ways according to different DTH hammers.
A bit always gives a bigger hole than the stated bit diameter.
Cross bits: Can be a maximum of +1mm due to manufacturing tolerance
Button bits: Some bit designs can be a maximum +3mm to compensate for fast diameter wear.
Every DTH Bit has its mark and number and we also can print your logo as your request.
