We supply extension rods, MF rods, and guide rods. The sizes include H32, H38, D32, D39, D46, D52, D56, D64, D76, and D87, with lengths ranging from 3050mm to 6095mm.
We offer five main types of drill bits: cross bits, button bits, drop center button bits, retrac button bits, and drop center retrac button bits.
Button bits are available in diameters ranging from 51mm to 127mm. Cross bits are available in diameters ranging from 50mm to 65mm.
SDA Bolts are primarily used in geotechnical and engineering projects such as slope stabilization, tunneling pre-support, foundations using micropiles, railway support systems, and metro projects.
Our standard thread configurations include R32, R38, T38, T45, and T51 to ensure compatibility with different rock drilling rigs.
Depending on the specific bit diameter and configuration, the R32 button bits feature gauge tooth angles of either 30° or 35° to optimize penetration rates in various rock formations.
