Stanley CH1533101 Underwater Chipping Hammer .580 Hex Oval

The Stanley CH1533101 is a professional-grade underwater hydraulic chipping hammer built on the rugged CH15 series, engineered for light to medium duty chipping, concrete breaking, and scaling work in subsea and submerged applications. This model is especially suited for commercial divers, marine contractors, and underwater maintenance teams who need a nimble yet powerful tool for confined or hard-to-access locations. 

At approximately 16 lbs (7.25 kg) with a 17″ (43 cm) overall length, the CH1533101 combines a high power-to-weight ratio with compact dimensions that make it easy to handle underwater. It features an ergonomic “D” handle with an integrated floating trigger that engages with minimal pressure, enhancing user comfort and control while reducing fatigue during extended use. The tool accepts .580″ hex shank, oval-collar tool bits with a solid bit retainer — including chisels and moils — suited for scaling concrete, rock, masonry, or metal surfaces below the waterline. 

Designed for use with open-center hydraulic systems delivering 7–9 GPM (26–34 L/min) at 1000–2000 PSI (70–140 bar), the CH1533101 operates efficiently in a wide range of hydraulic applications. It includes quick disconnect couplers and hose whips for easy setup and connection to a power unit or remote hydraulic supply. The trigger is recessed within the handle to help prevent accidental engagement, and the body is insulated against shock and heat for increased durability and diver comfort. 

Ideal for underwater construction and repair tasks where precision and mobility are critical, the CH1533101 delivers reliable, ergonomic performance in demanding subsea conditions.
