Rotary Hammer DeWALT DCH333X2-QW

The DeWALT DCH333X2-QW rotary hammer is a cordless percussion tool designed for drilling and light chiselling in concrete and masonry. It is equipped with a brushless motor and an SDS Plus chuck, delivering impact energy of 4.2 J and a no-load speed up to 1000 RPM. The tool is powered by a 54 V battery system with two 9 Ah batteries included, offering extended runtime for demanding on-site tasks. The unit weighs 4.9 kg and features the familiar yellow DeWALT housing for visibility on the jobsite.

Advantages

The brushless motor increases efficiency and reduces maintenance compared with brushed alternatives, while the SDS Plus chuck ensures fast and secure bit changes. An impact energy of 4.2 J provides reliable performance for drilling up to 30 mm in concrete. Supplied with two batteries, the kit reduces downtime by allowing continuous work while one battery charges. The compact cordless design removes the need for a mains connection and improves mobility on construction sites.

Suitable for

• Drilling holes in concrete, brick and masonry up to 30 mm diameter
• Anchor and rebar hole preparation on construction sites
• Light chiselling and demolition tasks where controlled impact is required
• Work in locations without easy access to mains power

How to use

Select an SDS Plus bit appropriate for the hole diameter and material. Fit the bit into the SDS Plus chuck until it locks, then set the tool to the drilling or hammer mode depending on the task. Start drilling at low speed to establish the pilot hole, then increase to the required speed up to the specified no-load RPM. Apply steady forward pressure without forcing the tool; allow the percussion mechanism to do the work. For extended work periods, swap the batteries as needed and follow the battery manufacturer guidelines for charging and storage.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust extraction or a dust mask when drilling concrete. For optimum performance and battery life, store batteries at moderate temperatures and use manufacturer-approved chargers. Inspect SDS Plus bits and the chuck regularly and replace worn accessories to maintain drilling accuracy and safety.
