Rock Drilling Equipment

38 mm R28 Top Hammer Bit

A 38 mm top-hammer rock drill bit with a R28 threaded connection.

ÜRÜN AÇIKLAMASI

The 38 mm R28 Top Hammer Bit uses tungsten-carbide buttons to transfer impact and rotation from the R28 drill string to the rock face. This size is suited to small-diameter surface and drifting work.

Button profile and flushing layout must be selected for rock hardness, abrasiveness and hole-cleaning capacity. Matching the shank adapter, rod, coupling and bit to the same thread standard helps prevent energy loss and connection damage.
