Key Differences in Accessories and Features

Included accessories count

Edge: Bosch 4.0 Amp StarlockPlus Kit

You get more blades with the Bosch GOP40-30C StarlockPlus Oscillating Multi-Tool Kit. This model includes 32 accessories in its package. The Bosch GOP40-30B StarlockPlus Oscillating Kit provides 30 accessories instead. Both kits offer a wide range of tools for various tasks like flush-cutting, sanding, and grinding. The two-extra items in the GOP40-30C give you slightly more versatility right out of the box. This small difference matters if you plan to tackle diverse projects without buying separate blade packs later.

Storage case type

Edge: Bosch 4.0 Amp StarlockPlus Kit

The storage solution differs between the two kits. The Bosch GOP40-30C comes with a durable case to hold its 32 accessories. The Bosch GOP40-30B uses a bag for its 30 accessories. A case typically offers better protection and organization for your tools. It keeps blades secure and prevents loss during transport. A bag is lighter and more flexible but may not protect edges as well. If you carry your kit to job sites regularly, the case provides superior durability and structure for your investment.

LED illumination

Edge: Bosch 4.0 Amp StarlockPlus Kit

The Bosch GOP40-30C includes an LED light for illumination in dark work areas. This feature helps you see clearly when doing flush cuts or working in tight spaces. The Bosch GOP40-30B does not list an LED light in its specifications. Without this light, you may need an external source to see your workpiece clearly in shadows. The LED adds practical value for precision tasks. It allows for better accuracy when using plunge or segment blades in low-light conditions.

Oscillating arc angle

Edge: Bosch 4.0 Amp StarlockPlus Kit

The Bosch GOP40-30C specifies a 3.0-degree oscillating arc. This angle delivers better accessory utilization and increased productivity. The Bosch GOP40-30B data does not list a specific arc angle. A defined arc can impact how efficiently the tool transfers torque and cuts material. The 3.0-degree specification suggests optimized performance for specific tasks. If the GOP40-30B has a similar or different arc, it is not stated in the provided data. The explicit mention in the 30C model highlights its design focus.

Constant response circuitry

Edge: Bosch 4.0 Amp StarlockPlus Kit

The Bosch GOP40-30C features constant response circuitry. This technology maintains the desired speed under load, ensuring consistent performance during heavy use. The Bosch GOP40-30B description mentions a 4.0-amp motor with reinforced metal gearing but does not explicitly list constant response circuitry. While both have heavy-duty power, the circuitry in the 30C offers added control. It prevents the tool from slowing down when pressure is applied. This feature supports sustained productivity for demanding cutting and grinding jobs.

Weight and dimensions

Edge: Tie

Both tools share identical physical specifications. They each weigh 3.3 pounds. The dimensions are 11 inches in length, 2.5 inches in width, and 3.75 inches in height. This consistency means you get the same balance and handling feel with either model. The lightweight design reduces fatigue during extended use. Since the size and weight are the same, your choice should depend on accessories and features rather than ergonomics. Both are compact and easy to maneuver in tight spaces.

Which Bosch oscillating tool kit fits you best

Need extra blades and a hard case

Our pick: Bosch 4.0 Amp StarlockPlus Kit

The Bosch GOP40-30C includes 32 accessories and a protective case. This model adds an LED light for dark work areas. It also features a constant response circuitry to maintain speed under load. If you want more tools and better illumination, this kit provides the extra utility you need for complex tasks.

Want a standard kit with fewer items

Our pick: Bosch GOP40-30B StarlockPlus Oscillating Kit

The Bosch GOP40-30B offers 30 accessories in a bag. It shares the same 4.0-amp motor and variable speed range as the other model. If you do not need the extra two blades or the LED light, this kit delivers the core performance you need. It is a straightforward option for general use.

Prioritize constant speed under heavy load

Our pick: Bosch 4.0 Amp StarlockPlus Kit

The Bosch GOP40-30C includes constant response circuitry. This feature maintains the desired speed when the tool encounters resistance. The Bosch GOP40-30B does not list this specific circuitry in its data. If you frequently cut dense materials, this electronic control helps ensure consistent performance throughout your work without manual speed adjustments.
