Overview of the Bosch GOP12V-28N

The Bosch GOP12V-28N is an oscillating multi-tool that features brushless motor technology for efficient power delivery. It utilizes the Starlock accessory system which allows for quick and secure accessory changes without any tools required.

One of the key features of this multi-tool is its compact size and light weight at only 2.5 lbs. This makes it easy to maneuver into tight spaces and reduces fatigue during extended use. Despite its small size, it still delivers up to 50% more power than previous Bosch 12V oscillating tools.

It is powered by Bosch's 12V Max EC Brushless motor which provides high power while generating less heat. The brushless design also requires less maintenance compared to brushed motors. With the GOP12V-28N, users can expect up to 30 minutes of runtime when using a 12V 2.0Ah battery.

The Starlock accessory mount is another standout feature, allowing accessories to be changed quickly without any additional tools. There is no slipping or losing accessories, even during heavy use. Bosch offers a wide range of Starlock accessories from sanding pads, blades, scrapers and more.

Overall, the GOP12V-28N combines brushless power, the versatile Starlock system and a compact 12V platform to create a highly capable oscillating multi-tool suitable for professional use.

For users looking for a more complete cordless tool system, Bosch also offers combo kits like the Bosch GXL18V-270B22. This 18V 2-tool combo kit includes the GOP12V-28N along with the 18V Chameleon Drill/Driver that has Bosch's innovative 5-in-1 Flexiclick system.

The Flexiclick system allows the Chameleon drill to convert between an inline driver, 90° angle drill, offset driver, right angle attachment, and a conventional pistol grip driver. This provides versatility to tackle various applications and access tight spaces. It delivers up to 760 in-lbs of max torque.

Having both the GOP12V-28N oscillating multi-tool and the 18V Chameleon Drill/Driver in one kit provides users with a highly versatile 2-tool system. The oscillating multi-tool excels at detail work like sanding, grinding, cutting, and scraping while the Chameleon driver handles drilling and driving tasks. Together they form a compact but powerful combo kit.

The kit also includes two 18V SlimPack 4.0Ah batteries that provide long runtime. With brushless motors, the Starlock accessory system, and Flexiclick versatility, the Bosch GXL18V-270B22 combo kit is an excellent choice for professionals, remodelers, and DIYers looking for a portable but capable 2-tool setup.

Performance

The Bosch GOP12V-28N delivers impressive performance for a compact 12V oscillating multi-tool. It is powered by Bosch's proprietary EC Brushless motor, which provides efficient power output while generating minimal heat.

The variable speed dial allows users to adjust the speed from 10,000 to 20,000 oscillations per minute to match the application. At lower speeds, the GOP12V-28N excels at detailed sanding and grinding tasks. At higher speeds, it can power through wood, plastic and even metal cutting jobs.

The tool comes without a battery, allowing buyers to choose from Bosch's 12V Max line of lithium-ion batteries. With a 2.0 Ah slim pack battery, users can expect around 20 minutes of continuous runtime. The larger 4.0 Ah packs provide nearly 45 minutes of runtime for extended use. While not best in class, the runtime is respectable for a 12V oscillating multi-tool.

Overall, the brushless motor provides strong, consistent power in a compact form factor. The variable speed gives users good control over the tool's performance.

For users needing even more power, Bosch also offers the Bosch GOP18V-28N: 18V EC Brushless StarlockPlus Oscillating Multi-Tool Bare Tool. This upgraded 18V model features the same brushless motor technology but with a higher voltage battery pack for increased performance. The GOP18V-28N provides up to 20% more power while still maintaining speed control up to 20,000 oscillations per minute.

The higher voltage allows the brushless motor to work more efficiently with improved torque. This makes the GOP18V-28N better suited for demanding applications like aggressive cutting and sanding in wood and metal. The StarlockPlus quick change system also allows fast accessory changes.

For professional users or applications requiring maximum power in an oscillating multi-tool, the Bosch GOP18V-28N is a great option. It delivers more power than the 12V GOP12V-28N while maintaining the advantages of Bosch's brushless motor technology. The higher voltage 18V battery platform provides the best balance of performance and runtime.

Comfort and Handling

The Bosch GOP12V-28N is designed with comfort and ease of use in mind. The multi-tool has an ergonomic grip that allows for a secure hold during operation. The grip has soft rubber overmolding that makes it comfortable to hold, even during extended use.

Vibration levels are well controlled thanks to the brushless motor and counterbalance mechanism. There is minimal vibration transferred to the operator's hands. This reduces fatigue and allows the user to work for longer periods comfortably.

Changing accessories is fast and simple with the tool-free Starlock blade changing system. Accessories can be inserted directly into the multi-tool without any tools required. There is an auto-lock system that secures accessories once they are mounted. This allows the user to change blades and attachments in just seconds for maximum productivity.

Overall, the ergonomic design, low vibration, and quick accessory changes make the Bosch GOP12V-28N comfortable and easy to handle for a wide variety of oscillating tool applications.
