APT M137 Rock Drill, in its wet‑drilling version is a heavy‑duty pneumatic drilling tool engineered for high‑performance use in demanding environments. Equipped with a 1″ × 4‑1/4″ chuck, a 2‑3/8″ bore, and a 2‑5/8″ stroke, it produces approximately 2,300 blows per minute (BPM). It is designed with the optional wet‑drilling configuration — including a wet‑tube and swivel assembly — which enables water or flush fluid to flow through the drill bit, helping to control dust, cool the bit, and improve drilling efficiency. The dry/wet adaptability is noted in official specifications showing the model “available in wet or dry.” This version offers a robust build with balanced ergonomics so operators can tackle anchor holes, utility penetrations, quarry secondary holes and hardened rock faces where wet‑drilling is needed for either regulatory compliance (dust control) or improved bit life and hole quality.
