Power Source and Motor Specs
Power source type
The Bosch GOP18V-34B14 is a cordless tool powered by an 18V battery system. It includes a CORE18V 4 Ah Advanced Power battery in the kit, offering portability and freedom from cords. The Bosch GOP40-30B is a corded model with a 4.0-amp motor. You must plug it into a wall outlet to operate. This limits movement but ensures consistent power without battery management. For jobs where you need to move around a large site or work in areas without easy outlet access, the cordless option is more practical. If you work in a fixed shop location, the corded model removes battery weight and charging concerns.
Motor technology
The GOP18V-34B14 features a brushless motor. This design typically offers longer motor life, increased efficiency, and better heat management than brushed motors. The product data states it delivers power and speed comparable to corded oscillating multi-tools. The GOP40-30B uses a traditional brushed 4.0-amp motor with reinforced metal gearing. Brushed motors are generally more robust against heavy loads but have higher friction and wear over time. The brushless motor in the 18V kit provides a modern efficiency advantage. However, the corded motor provides direct electrical power without the degradation of battery charge. For long-term durability and efficiency, the brushless design holds the edge.
Included accessories
The GOP40-30B kit is defined by its extensive accessory package. It includes 30 accessories and a carrying bag. This allows you to start cutting, sanding, grinding, and plunge-cutting immediately without buying separate blades. The GOP18V-34B14 kit includes the tool and the 4 Ah battery. The product data does not list any included blades or accessories for this model. You would need to purchase StarlockPlus compatible blades separately to begin work. For immediate versatility and value in terms of usable parts, the corded kit with 30 accessories is significantly more complete. The cordless kit focuses on the tool and power source only.
Ergonomics and weight
The cordless GOP18V-34B14 is designed for comfort with a redesigned handle and rotated battery position. It weighs only 1.6 ounces for the tool body, excluding the battery. The slim-grip design provides more control and less interference during flush-cutting. It also reduces vibration up to 80 percent compared to previous generations. The corded GOP40-30B weighs 3.3 pounds. While lightweight for a corded tool, it is significantly heavier than the bare tool of the cordless model. The cordless option offers superior balance and reduced fatigue for overhead or detailed work. The corded model’s weight is distributed by the power cord, which can be a factor in maneuverability.
Speed and oscillation
Both tools share the same maximum oscillation speed of up to 20,000 OPM. The GOP18V-34B14 features an improved cutting angle of 3.4 degrees for efficiency. The GOP40-30B includes a variable speed dial allowing you to adjust speeds from 8,000 to 20,000 OPM. This dial gives you precise control over the cutting speed for different materials. The cordless model’s data highlights the 20,000 OPM top speed and angle but does not explicitly mention a variable speed dial in the key specs. If you need to fine-tune speed for delicate sanding or aggressive cutting, the dial on the corded model offers clear operational control. The top speeds are identical.

The StarlockPlus interface ensures a secure three-dimensional blade grip for greater torque transfer.
Users prioritizing compact design and lightweight handling
The Bosch GOP18V-34B14 features a slim-grip design for improved comfort and control. It is notably lighter than the corded alternative, weighing just 1.6 ounces for the tool body. The compact dimensions measure 8.3 inches in length and 6.6 inches in height. This ergonomic form factor reduces hand fatigue during extended use while maintaining a top speed of 20,000 OPM for precision work.
Users requiring durable metal gearing and tool-free changes
The Bosch GOP40-30B includes a 4.0-amp motor with reinforced metal gearing for durability under heavy loads.
