CIR90 95mm CV Convex Face Semi-Ballistic Button Bit - DTH Rock Drill Bit
The CIR90 95mm CV Convex Face Semi-Ballistic Button Bit is a high-performance DTH drilling bit designed for efficient rock drilling in mining, quarrying, construction, and rock excavation applications. It features a 95mm bit diameter, convex face design, and semi-ballistic button configuration for balanced penetration, efficient rock breaking, and reliable drilling performance.
The carbide button layout includes 6 × 14mm, 4 × 12mm, and 2 × 10mm buttons, providing an optimized cutting structure for effective energy transfer and stable drilling in medium to hard rock formations.
The convex face profile helps concentrate drilling energy toward the center of the hole, while the semi-ballistic buttons provide a combination of penetration efficiency and wear resistance. The CIR90 configuration is suitable for DTH drilling applications where consistent hole quality and dependable bit life are required.
