Stanley BR87320 Underwater Hydraulic Breaker 1 x 1-1/8 Hex

The Stanley BR87320 is a robust underwater hydraulic breaker engineered for the most demanding subsea construction and demolition jobs. As the largest breaker in Stanley’s underwater BR87 lineup, this 90 lb class tool combines superior power-to-weight performance with a long piston stroke for high impact energy, making it ideal for breaking concrete, rock, coral removal, and driving rods and anchors during commercial diving operations. 

Built for reliable operation underwater, the BR87320 features a comfortable T-handle with a large on/off trigger for precise control and a feathering valve for smooth start-up and easy bit placement. Its diaphragm-style accumulator boosts blow energy while reducing recoil, and rugged construction — including a four tie rod design and stainless-steel components — ensures durability and ease of service in tough environments. Capable of operating in any orientation with an open-center hydraulic circuit, this breaker accepts standard 1-1/8″ × 6″ hex shank bits and operates within a 7–9 GPM (26–34 LPM) flow range at 1500–2000 PSI.
