Up to now, Our Cir series bits have been exported to Brazil, Pure, American, South African, South Aisa etc areas. The drill bits are normally used on limestone,Granite, bluestone etc.  YK05 button inserts can let the drill bits bear any hardness rocks. Special design can improve the drilling efficiency.

Button bits should be reground when penetrati on rat es 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.

Standard Shank used on CIR series Hammer, Generally the DTH bits are always same as Atlas Copco, Sandvik, Furukawa etc drill rig. 

The connection have two different ways according to different DTH hammers.  

All bit diameters are larger than the given dimensions in the catalog
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.

The minimum diameter for all button bits is +1.5mm above the
given dimensions
Keep in mind that a bit always gives a bigger hole than the stated bit diameter.Every DTH Bit has it's mark and number and we also can print your logo in it according to your request.
