1. Long life span: the wear-resist of tungsten carbides is 10-20 times
higher compared with other similar materials, which greatly extends
the life of the carbide bits;
2. High drilling efficiency: the high grade hardness of the
carbides can always stay sharp, which could increase the drilling
speeds too;
3. Stable drilling speed: the bit is scraped and cut to break the rock.
4. Good performance: strong wear resistance, good diameter protection which will make the cutting teeth
more efficiently.
5. Lower cost.
Service
A.Quick response in 24 hours when there are any further inquiries,
complaints,testing feedback.later order confirmation etc.
B.Online Technical support covering dis-assembly, maintenance,

painting color, logo, packing etc., are also available.
we has a comprehensive range of DTH drill bits to match all
conceivable applications. Each bit is made from quality alloy
steel, and has been precision machined to produce a perfect body,
heat treated to the required hardness, given surface compression
for fatigue resistance, and fitted with precision buttons
manufactured in-house. These are deigned for specific applications
for all rock types, hardness's and condition. Bit life and rate of
penetration are the most important criteria in selecting the right
bit for a particular application.
