Brushless Motor Technology: The core tools in this kit (Drill; Impact Driver; SDS) all feature brushless motors. This removes the friction and heat associated with traditional carbon brushes; resulting in significantly longer tool life; cooler running temperatures; and better battery efficiency per charge. All-Round Drilling Capability: You are covered for every material. The DCD796 Combi Drill handles standard wood; metal; and light masonry drilling. When the going gets tough (reinforced concrete or hard brick); the DCH273 SDS+ Hammer steps in with pneumatic impact power. Precision and Power: The DCF887 Impact Driver is widely regarded as a market leader; offering a massive 205Nm of torque for driving long screws; yet it features a 3-speed "PrecisionDrive" mode to prevent stripping heads on smaller fixings. Perform & Protect: The DCH273 SDS drill features floating handle mechanics that drastically reduce vibration (rated at just 6.6m/s²). This allows you to use the tool for longer periods without risking fatigue or hand-arm vibration issues. Intelligent Lighting: Both the Combi Drill and Impact Driver feature LED "Halo" rings or base-mounted lights to illuminate the workpiece without casting shadows from the chuck. The standalone DCL040 Torch adds a versatile; pivoting floodlight for loft or under-floor work. XR System Compatibility: The included 4.0Ah batteries offer an excellent middle-ground between the lighter 2.0Ah packs and the heavier 5.0Ah variants; providing ample run-time without making the tools cumbersome to hold overhead.
