FLEX 24V 6-Tool vs 4-Tool Kit Comparison
Number of tools
The FLEX 24V Brushless 6-Tool Combo Kit includes six distinct power tools in its package. This list features a hammer drill, an impact driver, a circular saw, a multi-tool, and a reciprocating saw. In contrast, the FLEX 24V 4-Tool Combo Kit with STACK PACK Storage contains only four tools. You get a drill driver, an impact driver, a reciprocating saw, and a work light. If you need a circular saw or oscillating tool, the six-tool kit provides those specific capabilities. The four-tool option leaves those tasks to other equipment or different tools entirely. You must decide if the extra two tools justify the kit choice.
Included tools
Tool variety defines the practical value of each kit. The six-tool model brings a 7-1/4 inch circular saw with a 2-9/16 inch depth of cut and an oscillating multi-tool running at 20,000 OPM. It also includes a hammer drill. The four-tool model swaps these for a dedicated work light and lacks the saw and multi-tool. While the four-tool kit includes a substantial storage system with rolling boxes and cases, the six-tool kit focuses purely on tool count. You get more cutting and grinding options with the larger set. The smaller kit offers organization but fewer cutting capabilities.
Voltage
Both kits operate on the same 24V lithium-ion platform. This shared voltage ensures that batteries are interchangeable across both sets. You can use the batteries from the six-tool kit in the four-tool tools and vice versa. The motor technology is also identical, utilizing brushless motors for efficiency. This means performance characteristics like torque and speed are comparable for the tools they share. The impact driver in both kits delivers 1,800 in-lbs of torque. Choosing between them does not involve a power base difference, as the electrical foundation remains consistent.
Battery capacity
The six-tool combo kit includes two batteries with varying capacities: a 2.5 Ah battery and a 5.0 Ah battery. This mix allows you to choose between lighter weight for overhead work and longer runtime for heavy tasks. The four-tool combo kit specifies 2.5 Ah batteries in its key specs. The features section mentions two 2.5Ah lithium-ion batteries. It does not list a 5.0 Ah option. If you need extended runtime without swapping frequently, the six-tool kit provides a higher capacity option. The four-tool kit relies on the standard capacity cells.
Chuck size
Both kits provide compatible chuck sizes for standard accessories. The drill and hammer drill in the six-tool kit feature a 1/2 inch chuck. The impact driver uses a 1/4 inch hex quick-change system. The four-tool kit mirrors this setup with a 1/2 inch chuck on its drill driver and a 1/4 inch hex on its impact driver. This consistency means your existing bits and drill chucks work equally well with either kit. You do not lose compatibility by choosing the smaller set. The mechanical interface for holding bits remains identical across both product lines.
Storage system
The four-tool kit distinguishes itself with a comprehensive storage solution. It includes the STACK PACK system, featuring a rolling tool box, a medium tool box with a removable tray, and a suitcase with four organizer cases. The six-tool kit description does not mention any storage containers or cases. It focuses solely on the tools and charger. If you require immediate organization and transport capability, the four-tool kit is the superior choice. The six-tool kit leaves storage to your existing infrastructure. You gain convenience with the four-tool set but lose tool variety.
Power source
Both kits are fully cordless and rely on lithium-ion batteries. This power source allows for unrestricted movement around a job site. Neither kit requires a constant electrical outlet connection. The six-tool kit includes a 160W fast charger to replenish the 2.5 Ah and 5.0 Ah batteries. The four-tool kit also includes a 160W fast charger for its 2.5 Ah batteries. The charging speed and power source type are identical. You benefit from the same cordless freedom regardless of which kit you select. The runtime depends on the specific tool and battery capacity chosen.

Professionals requiring impact driver torque and reciprocating saw speed
You need high torque for fastening and speed for cutting. This kit includes the FX1351 impact driver delivering 1,800 in-lbs of torque. It also features the FX2271 reciprocating saw with 4,000 RPM. Both tools use the same 24V brushless platform, ensuring consistent performance and efficiency across your most frequently used power tools.
DIYers wanting a multi-tool for detailed work
You need precision for cutting and sanding in tight spaces. This six-tool kit includes the FX4111 oscillating multi-tool with 20,000 OPM. It offers high-speed cutting with vibration suppression.
