Tool Count and Kit Scope

Number of tools

Edge: FLEX 24V Brushless 4-Tool Combo Kit

The FLEX 24V Brushless 2-Tool Drill and Impact Driver Kit includes two essential power tools. You get a 1/2-inch drill driver and a 1/4-inch quick eject impact driver. This setup focuses on drilling and fastening tasks. The FLEX 24V Brushless 4-Tool Combo Kit expands your options significantly. It adds a reciprocating saw and a work light to the drill and impact driver. This gives you four distinct tools for more varied jobs. If you need cutting or illumination capabilities, the four-tool kit offers more versatility. The two-tool kit is simpler but covers the basics effectively.

Included tools

Edge: FLEX 24V Brushless 4-Tool Combo Kit

Both kits feature a drill driver and an impact driver, but the specific models differ. The two-tool kit includes the FX1171T drill driver with turbo mode and the FX1371A impact driver with multi-mode control. These are higher-performance variants with more torque. The four-tool kit includes the FX1151 drill driver and FX1351 impact driver, which are slightly less powerful but still robust. Additionally, the four-tool kit provides the FX2271 reciprocating saw and FX5111 work light. These extra tools allow you to cut materials and illuminate dark workspaces without buying separate units. The two-tool kit lacks these specific additions.

Maximum torque

Edge: FLEX 24V Brushless 2-Tool Drill and Impact Driver Kit

Torque determines how much twisting force a tool can apply. The two-tool kit features the FX1371A impact driver, which delivers 2,500 in-lbs of torque. Its drill driver, the FX1171T, provides 1,400 in-lbs. The four-tool kit includes the FX1351 impact driver with 1,800 in-lbs of torque and the FX1151 drill driver with 750 in-lbs. The tools in the two-tool kit are clearly more powerful. They handle larger fasteners and tougher materials with greater ease. If high torque is critical for your heavy-duty projects, the two-tool kit’s specific drivers offer a clear advantage in raw power.

Battery capacity

Edge: FLEX 24V Brushless 2-Tool Drill and Impact Driver Kit

Battery capacity affects runtime between charges. The two-tool kit includes one 2.5Ah battery and one 5.0Ah battery. This mix allows you to swap between a compact option and a high-capacity option. The four-tool kit includes two 2.5Ah batteries. It lacks the larger 5.0Ah cell. While having two identical batteries is useful for rotation, the 5.0Ah battery in the two-tool kit provides significantly longer runtime. For tasks that require extended use without stopping to recharge, the larger capacity battery in the two-tool kit is more beneficial.

Weight and size

Edge: FLEX 24V Brushless 2-Tool Drill and Impact Driver Kit

The physical dimensions and weight of the kits differ notably. The two-tool kit weighs 17.6 pounds and measures 16.9 inches in length. It is lighter and more compact. The four-tool kit weighs 25 pounds and measures 10 inches in length but is taller at 8 inches. The four-tool kit is significantly heavier due to the extra tools and batteries. If you prioritize portability or need to transport the kit frequently in a vehicle, the lighter two-tool kit is easier to handle. The four-tool kit is bulkier and heavier, which may impact convenience during transport.

Which FLEX 24V Kit Suits Your Needs
