The HEM550 drill from TEI Rock Drills features the new TE550 drifter. This design is more durable than the dry firing that is destructive to most hammers. It allows for an oil ìcushionî to slow the piston when the shank is pulled forward. Completely radio- or cable-controlled, this drill allows the operator to enjoy the comfort of the excavator cabin. Hole sizes for the HEM550 are 2Ω to 3Ω inches.
