Design Highlights

• Hammer to Drill a hole of dia 115 – 140 mm (4 1/2”– 5 1/2”).
• S47S4 is a valveless type hammer designed for high performance at low operating air pressures
• S4 bit has a strong robust design to withstand heavy duty application and it does not use foot valves which reduces the possibility of hammer failure.
• S47S4  Hammer maximizes energy output and reduces service requirements
• Wear sleeve is not reversible
• Three  Start threads on Top sub and Drive sub ensure easy coupling/uncoupling of hammer.
• All critical internal components are heat treated under strict control to maximize tool longevity.
• An overall cost-effective and user friendly tool for use in the most demanding conditions.
