Chave de impacto DeWALT DCF900P2T-QW 1/2" sem escovas 18 V, 1898 N·m, bateria 5 Ah, 2 baterias, carregador, mala

The DeWALT DCF900P2T-QW is a 1/2" impact wrench designed for demanding fastening and loosening tasks. With a maximum torque of 1898 N⋅m and a brushless motor, this battery-powered tool combines high torque output with improved efficiency and reduced maintenance. The kit includes an 18 V, 5 Ah lithium-ion battery which supports extended runtime. Compact and relatively lightweight for its class, the DCF900P2T-QW features a built-in light and the familiar DeWALT black and yellow finish suitable for professional environments.

Advantages

The brushless motor delivers better energy efficiency and longer tool life compared to brushed alternatives. High maximum torque (1898 N⋅m) enables the tool to handle heavy-duty tightening and loosening jobs. The included 18 V, 5 Ah lithium-ion battery provides extended runtime and consistent power delivery under load. A built-in light improves visibility in poorly lit work areas, while the compact design enhances maneuverability in tight spaces. The tool’s adjustable speed allows for greater control across different applications.

Suitable for (tasks / use cases)

• Automotive wheel and suspension work requiring high torque
• Heavy machinery assembly and maintenance
• Industrial and construction fastening where high torque is needed
• Outdoor maintenance work in low-light conditions

How to use

Ensure the battery is fully charged before use and insert it securely into the tool. Select the appropriate socket for the fastener and fit it onto the 1/2" anvil. Use the adjustable speed control to set an initial lower speed for engagement, then increase speed as needed to achieve the required torque. Hold the tool firmly with both hands where possible and engage the trigger to apply torque. When loosening fasteners, set the tool to the reverse direction and use controlled bursts to prevent sudden release. After use, remove the battery and store the tool and battery in a dry, ventilated area.

Recommendations

For optimal performance, use the DeWALT 5 Ah battery supplied with the tool or DeWALT batteries of equivalent specifications. Wear appropriate personal protective equipment such as eye protection and gloves. Avoid prolonged continuous operation at maximum torque to reduce heat buildup; allow periodic cooldowns during extended heavy use. Regularly inspect sockets and fasteners for wear to ensure safe and effective operation.
