New Bosch EXPERT Angle Grinders: Cutting performance, user safety and comfort at your fingertips

Angle grinders suitable for heavy-duty work

The operations of grinding, cutting and deburring require equipment capable of maintaining consistent performance. With the EXWS18V2-230P (cordless) and EXWS20-150SB (corded) models, Bosch targets a variety of uses, from metalworking to mineral materials.

These two machines are based on a robust design and wear-resistant materials, adapted to the constraints of construction sites. They comply with the safety requirements defined in particular by the standard EN 60745 (safety of portable power tools), which governs the design of portable equipment used by tradespeople and construction companies.

In the field, these grinders are integrated into the routine operations of a metalworking workshop, of a major construction project or even of an industrial maintenance intervention.

Bosch EXPERT angle grinder motors and cutting performance

A cordless grinder with equivalent power to a corded one

The EXWS18V2-230P angle grinder based on an engine BITURBO Brushless 2x18Vdesigned to deliver power equivalent to a 2700W corded tool. It can reach up to 45 cuts per load, a concrete indicator for teams working on repetitive series.

This level of performance allows for working with different materials:

• ferrous and non-ferrous metals
• concrete and masonry
• tiles and stone
• composite materials

A design office or a project manager can thus integrate this type of tool into cutting protocols requiring speed and autonomy, particularly in the finishing stages.

"It delivers power equivalent to a 2700W corded tool for fast and efficient work."

A corded grinder geared towards precision and durability

The EXWS20-150SB modelequipped with an engine 2000W Brushless, stands out with a claimed power output 65% higher than that of a 1200W reference model.

This configuration is suitable for applications such as:

• weld bead trimming
• deburring of molded parts
• preparation of metallic surfaces

In a constrained workshop or construction site context, this power makes it possible to reduce implementation time, while limiting downtime cycles related to overheating.

One operational limitation remains, however: the wired version requires a dependence on a power supply, which may restrict its use in areas not connected to the grid.

Ergonomics and ease of use on the construction site

Balance and maneuverability of tools

The EXWS18V2-230P enjoys a optimized center of gravity, facilitating handling in different working positions. Its 90° rotating motor housing allows the tool to be adapted to the cutting or grinding configuration.

This type of design meets the ergonomic constraints identified by construction ergonomists, particularly to limit musculoskeletal disorders related to prolonged postures.

Compactness and precision for finishing work

The EXWS20-150SB adopts a compact format with a thin handlefacilitating precise interventions. This criterion is crucial for craftsmen carrying out finishing work or adjustments on metal structures.

A concrete example: when installing a metal railing, deburring the welds requires a handy tool that allows for precise control without altering the material's surface.

Safety devices and user protection

Integrated active security features

Both models incorporate several systems designed to reduce the risk of accidents:

• KickBack Control : motor stops in case of disc blockage
• dead man's switch : immediate stop upon release
• Rapid disc braking
• overheat protection

The wired version includes additional features:

• Drop Control : stop in case of a fall
• Restart Protection : prevents an unexpected restart

These devices meet the requirements for risk prevention on construction sites, particularly within the framework of the single document for the assessment of occupational risks (DUERP).

"KickBack Control reduces the risk of injury if the disc jams."

"Restart Protection prevents the engine from automatically restarting after a power outage."

Reduction of vibration and operator fatigue

The presence of a anti-vibration handle The wireless model helps reduce fatigue. This is essential for prolonged work, where exposure to vibrations can impact the health of operators.

Thermal management and equipment durability

The EXWS20-150SB integrates a direct cooling system combined with temperature monitoring. A removable dust filter protects the internal components, limiting fouling.

This type of device is part of a logic of Preventive maintenance, often recommended by technical departments and equipment fleet managers.

An LED indicator provides real-time information on the tool's status, facilitating monitoring of usage on site.

Compatibility and integration into existing systems

The EXWS18V2-230P cordless grinder is compatible with the system Bosch Professional 18V and the alliance AMPShareenabling battery interoperability between several partner brands.

This compatibility is an advantage for companies wishing to streamline their equipment fleet and limit costs related to energy-efficient equipment.

A response to the demands of the field

These two angle grinders are part of an evolution in power tools towards more power, safety and ergonomicsThey meet the needs of professionals facing constraints of intensity of use and diversity of materials.

However, their effectiveness depends on the conditions of use: choosing the right disc, respecting rotation speeds and regular maintenance remain crucial to guaranteeing performance and safety on site.
