APT M137 Rock Drill is a robust midsize pneumatic drilling tool crafted for high‑intensity wet‑drilling operations in harsh environments. Featuring a 7/8″ ×  4‑1/4″ chuck, a substantial 2‑3/8″ bore, and a 2‑5/8″ stroke, it delivers approximately 2,300 blows per minute (BPM). Optimized for wet‑drilling use, this model incorporates a water‑tube and swivel assembly that allows controlled water or slurry flow into the drill hole, enhancing cooling, dust suppression, and bit life under tough rock‑face or concrete conditions. Designed with professional durability in mind, it offers rugged internal construction, efficient impact energy transfer, and operator‑friendly ergonomics for demanding tasks like quarry hole drilling, anchor‑hole preparation, or secondary blast‑hole creation. This tool balances power, precision, and reliability to meet the needs of heavy‑use utility, industrial, and construction sites where wet‑drilling is preferred or required for safety and performance.
