CAT 1500 W SDS-Plus Rotary Hammer - 32 mm Chuck, 5.0J Impact Energy (DX21)

High-Velocity Kinetic Force and Structural Demolition Strength

 

The CAT DX21 is an industrial-strength powerhouse designed for the most demanding jobsite applications. Engineered to bridge the gap between standard rotary hammers and heavy demolition breakers, it utilizes a high-compression pneumatic system to deliver a massive 5.0 Joules of impact energy. This tool provides the raw strength needed for high-diameter drilling and intensive chiselling into reinforced concrete and stone with minimal operator effort. Whether you are performing structural renovations or professional site installations, the DX21 delivers the rugged durability and high-torque performance required for rapid, heavy-duty penetration.

 

The CAT 1500W SDS-plus Rotary Hammer (DX21) 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 or steel, and a specialized vario-lock mode for adjustable chisel angles.

Designed with operator comfort in mind, the DX21 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 the 5.0J impact energy benefit my work? The 5.0 Joules of energy allows the DX21 to strike significantly harder than standard impact drills, making it much faster and more efficient when drilling into hard concrete or stone.

2. Can I use this for standard drilling into metal? Yes, by selecting the Drilling Only mode, you can drill up to 13 mm in steel. Note that standard bits require an SDS-plus chuck adapter (sold separately).

3. What is the purpose of the Vario-Lock mode? Vario-Lock (Bit Rotation) allows you to rotate a flat chisel to the most effective angle for your specific task before locking it into the hammering-only mode.

4. Is there an indicator for maintenance? Yes, the DX21 features an auto-stop carbon brush system and a power indicator to help manage the tool's industrial service life.
