Bosch GOP 40-30 Professional Black, Blue, Grey, Red 400 W 20000 OPM

The Bosch GOP 40-30 Professional is a compact oscillating multi-tool engineered for cutting, sanding and flush sawing in a variety of materials. Powered by a 400 W motor, the tool delivers a variable idle oscillation rate from 8,000 to 20,000 OPM and an oscillation angle of 1.4°, allowing controlled material removal and precise results. Its compact dimensions (284 mm length, 85 mm height) and 1.5 kg weight make it suitable for extended use and working in confined spaces. The model is offered in several colour options and is intended for routine trade and home-improvement tasks where versatility and maneuverability are required.

Advantages

The tool combines a relatively powerful 400 W motor with a wide speed range to handle tasks from delicate sanding to aggressive cutting without frequent tool changes. The small oscillation angle supports accurate control and reduced vibration, while the compact, lightweight form factor improves access in tight areas and reduces operator fatigue. A universal accessory interface accommodates a range of sanding pads, blades and scraping tools to increase task flexibility.

How to use

Before operation, secure the correct accessory for the intended task and make sure it is fitted according to the accessory interface instructions. Connect the tool to a suitable power supply and set the oscillation rate according to the material and cutting or sanding requirements. Begin work with moderate pressure and allow the tool to perform the cutting or sanding action; increase speed or pressure only if the accessory is rated for higher loads. Keep a steady hand and move the tool smoothly along the work surface to achieve even results. Switch off and unplug the tool before changing accessories or performing maintenance.

Recommendations

Use fine-grit sanding pads for finish sanding and coarser grits or dedicated cutting blades for material removal. For renovation or plunge cuts, choose blades designed for the specific material and work at lower oscillation rates to improve control. Wear appropriate personal protective equipment and follow local safety regulations when working with power tools.
