APT M137 Rock Drill is a mid‑size pneumatic tool optimized for wet‑drilling use in tough rock and concrete environments. With its 2‑3/8″ bore and 2‑5/8″ stroke delivering approximately 2,300 blows per minute, this model integrates a 7/8″ × 3¼″ chuck and a dedicated wet‑drilling configuration (including wet‑tube and swivel options) for enhanced performance in drilled‑hole cooling and dust‑mitigation conditions. Built for durability and consistent output, the M137 features a heavy‑duty cylinder assembly and ergonomic handle design that allow operators to maintain control during intensive drilling. Its wet‑drilling setup allows water or slurry flow for better cleaning of holes and longer bit life—making it ideal for quarrying, secondary‑blast‑hole creation, and water‑aided rock or concrete drilling where dust control and cooling are essential.
