1.Enhanced fatigue strength through advanced forging technology.
2.High quality carbide in optimal sizes for stable longevity.
3.Precision inlaying technology prevents carbide detachment.
4.State of the art heat treatment ensures superior hardness and wear resistance.
5.Tailored design and specialized processing for extended service life across various rock formations.
SHANDIKE 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.
