Heavy Duty vs Cordless Specs
Power Source
The Berserker 1-9/16-Inch SDS-Max Rotary Hammer relies on a 13 Amp corded motor. This setup delivers consistent, unlimited runtime for heavy demolition or continuous drilling in thick concrete. You do not need to manage battery charge levels. In contrast, the Berserker 1-1/8-Inch Cordless Rotary Hammer uses a 20V Max lithium-ion system. It offers portability and freedom from cords, making it ideal for sites without easy power access. The cordless option includes two 4.0Ah batteries and a fast charger, allowing for extended work periods through quick swaps.
Impact Energy
When drilling into hard masonry, impact energy determines how fast the tool penetrates. The heavy-duty model provides 7.38 ft.lbs. (10 Joules) of impact energy. This high output allows it to tackle large-diameter holes in solid concrete with ease. The cordless model delivers 2.1 ft.lbs. (2.8 Joules) of impact energy. While lower, this is sufficient for standard SDS-Plus bits and smaller holes in brick or block. If you need to bore large holes in dense concrete, the corded unit has a clear advantage in raw power.
Weight and Portability
Weight significantly affects user fatigue during overhead or prolonged use. The heavy-duty rotary hammer weighs 16 pounds. Its substantial mass helps with stability but can cause arm strain during extended periods of use. The cordless model weighs only 7.2 pounds. This lighter design allows you to carry it up ladders or into tight spaces without excessive effort. For jobs requiring frequent repositioning or working in elevated areas, the lighter cordless tool is much easier to handle for long durations.
Chuck Size
The chuck size dictates the maximum bit diameter you can use. The heavy-duty tool features a 1-9/16-Inch SDS-Max chuck. This larger interface accepts bigger, more robust bits capable of handling high torque and heavy chipping tasks. The cordless model uses a 1-1/8-Inch SDS-Plus chuck. This standard size fits a wide range of common drill bits for general masonry work. If your projects require large-diameter core bits or heavy demolition chisels, the SDS-Max system is the necessary choice.
Included Tools
Both kits provide essential accessories for immediate use. The heavy-duty model is described as including a drill driver and hammer drill, though specific bits are not listed in the key specs. The cordless model comes with a more comprehensive kit. It includes three SDS-Plus drill bits, a point chisel, a flat chisel, two 4.0Ah batteries, a fast charger, a carrying case, and a metal depth gauge. For buyers wanting a complete, ready-to-work package out of the box, the cordless option provides more tangible accessories and power sources.
Motor Type
The motor technology influences durability and maintenance. The heavy-duty unit uses a 1,600-watt industrial motor. While powerful, brushed motors generate more heat and require brush replacements over time. The cordless model features a brushless motor. This design runs cooler, operates more efficiently, and reduces wear, extending the tool's lifespan. Brushless motors also offer better speed control and longer runtime per charge. For long-term reliability and efficiency, the brushless motor in the cordless model is superior.

This heavy-duty setup handles 1-9/16-inch SDS-Max bits for large concrete cores. The overload clutch protects your wrists during snagging. You get unlimited runtime for continuous heavy work without battery management.
Portable work in tight or elevated spaces
Pick this 7.2-pound cordless model for portability. The brushless motor runs cooler and lasts longer. It fits into tight areas with its compact size. You get 5,100 BPM for fast drilling in masonry. The two 4.0Ah batteries provide flexibility. This tool is ideal when you need to move frequently or work where cords are inconvenient.
Versatile tasks across multiple materials
This cordless option offers four modes, including drilling only and chisel adjustment. It handles concrete, brick, wood, and metal with its 2.1 ft.lbs. impact energy. The variable transmission gives you control. You can switch between SDS-Plus bits easily. This versatility makes it suitable for general renovation projects where you drill various materials.
