Ryobi 900 W SDS-Plus Corded Rotary Hammer - 26 mm Chuck, 4.0 J Impact Energy (ED-938)

High-Velocity Striking Power and Heavy-Duty Concrete Penetration

 

The Ryobi ED-938 is a powerhouse rotary hammer designed for industrial-strength tasks that require both raw power and precise control. Engineered to outperform standard impact drills, it uses an electro-pneumatic piston mechanism to deliver 4.0 Joules of impact energy, making it vastly superior for large-diameter drilling and breaking concrete. Whether you are a local builder or a serious DIY enthusiast, the ED-938 provides the strength needed for deep masonry penetration and light demolition with significantly less effort.

 

The Ryobi 900W SDS-plus Rotary Hammer (ED-938) is a versatile, high-performance tool built for strength and endurance. It features an intuitive 4-mode selector, allowing you to switch between rotary hammering (for concrete), hammering only (for chiselling), drilling only (for wood/steel), and a specialized vario-lock mode for adjustable chisel angles.

Designed with operator comfort in mind, the ED-938 is equipped with an anti-vibration system and a 360° rotating auxiliary handle to reduce fatigue during prolonged use. This rugged, user-friendly package ensures minimal downtime and maximum efficiency for residential upgrades, tile removal, or chasing wiring channels into masonry walls.

Frequently Asked Questions (FAQ)

1. How does this compare to a standard impact drill? A standard impact drill uses mechanical vibration, whereas the ED-938 uses an electro-pneumatic piston to deliver a powerful 4.0J 'hammer blow', making it far more efficient for concrete.

2. What is the benefit of the Vario-Lock mode? Vario-Lock allows you to rotate and lock a flat chisel or scaling bit at the specific angle required for the best leverage before switching to "Hammer Only" mode.

3. Is this tool compatible with standard straight-shank bits? No, this tool uses the SDS-plus connection system; standard bits would require a separate SDS-plus chuck adapter.

4. Does this product include a warranty? Yes, Ryobi power tools in South Africa typically include a 2-year warranty.
