Our
two-blade roof bolt PDC bit
is a professional anchor drilling tool optimized for coal mine roadway support, gas drainage holes, tunnel bolting, and underground rock reinforcement. This upgraded mining bolt bit adopts high-quality
1306 corrugated PDC cutters
and integrated tungsten carbide sintered body, solving the pain points of slow footage and easy tooth breakage of traditional anchor bits.
The unique corrugated cutter design greatly enhances the bit’s
impact resistance and abrasion resistance
. Compared with ordinary flat PDC cutters, the 1306 corrugated structure provides stronger rock-breaking force and lower drilling resistance, achieving
faster drilling footage speed
and higher construction efficiency. It is perfectly suitable for frequent working scenarios such as coal mine gas holes, water drainage holes, and roadway anchor bolt holes in soft and medium rock formations.
Featuring streamlined two-blade hollow concave structure, the bit discharges slag smoothly without jamming, with stable performance and ultra-long service life. As a professional mining drill bit manufacturer, we support full-size customization and strict factory inspection. Our
high-efficiency two-blade anchor PDC bits
are widely exported to mining areas in Africa, Southeast Asia, South America and other global GEO markets, winning recognition from numerous coal mine and engineering contractors.
