Perforator DEWALT DCH172E2T-QW

The DEWALT DCH172E2T-QW is a cordless perforator designed for professional applications that require reliable drilling and light chiselling in concrete, masonry and similar materials. Equipped with a brushless motor, the tool delivers efficient power transfer and extended runtime while maintaining a compact, lightweight form. The package includes a 2.0 Ah battery and a charger, enabling immediate use on site without a separate power supply.

Advantages

The brushless motor improves energy efficiency and reduces maintenance needs compared with brushed alternatives. Its lightweight construction and ergonomic handle provide better balance and reduced user fatigue during prolonged operation. The tool offers a combination of percussion drilling and rotary functions suitable for medium-duty drilling tasks, and the integrated battery and charger support quick deployment at job sites.

Suitable for

• Drilling holes in concrete and masonry for anchor bolts and fasteners
• Light demolition and chiselling tasks where controlled impact is required
• Installation work in construction and renovation projects with limited access to mains power
• Trade professionals who need a portable rotary hammer for routine on-site tasks

Key specifications

• Power system: brushless motor for improved efficiency
• Battery: 2.0 Ah lithium-ion battery included
• Operation modes: rotary and percussion drilling with selectable function
• Design: compact, lightweight housing with ergonomic handle
• Intended materials: concrete, masonry and similar hard substrates

How to use

Charge the included battery fully before first use and install it securely in the battery compartment. Select the appropriate drill bit or chisel for the task and attach it according to the tool's bit retention system. Choose the required operating mode (rotary or percussion) and set the drill speed or impact force if the tool provides adjustable settings. Start drilling with light pressure to establish the hole, then apply steady, controlled force while allowing the tool to perform the work. For chiselling, use short controlled strokes and reposition as needed for the desired material removal.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. For extended drilling in reinforced concrete, use carbide-tipped bits and allow intermittent cooling breaks to prevent overheating. Store the battery at moderate temperature and recharge after use to preserve battery life.
