KD-1ST Drifter
KD-1ST Drifter rotates separately from the strike mechanism. Rotary motor torque is large, allowing the use of large diameter bit.
KD-4 Drifter
KD-4 Drifter was developed for taphole opening, and is capable of both forward and backward (reverse) strike with 1 cylinder.
KD-1HG Drifter
KD-1HG Drifter has strong strike mechanism and can be used for both crushing and boring (drilling, punching).
