Description

The Metabo concrete grinding kit combines the powerful WEVBA 20-125 QUICK BL brushless angle grinder with a professional dust shroud and heavy-duty grinding handle installed by Diamond Tool Warehouse.

Instead of receiving a standard angle grinder that still requires conversion, contractors receive a purpose-built setup for concrete grinding and floor preparation.

The 2000W brushless motor provides strong performance for demanding trade and industrial work. Furthermore, Metabo’s variable-speed electronics maintain steady speed under load for more consistent grinding.

Diamond Tool Warehouse installs the professional dust shroud and strong grinding handle before supplying the kit. Therefore, the grinder arrives set up for connection to a compatible dust extractor and correctly selected 125mm diamond cup wheel.

What Makes This a Professional Grinding Kit?

A standard angle grinder does not provide the dust control or two-handed support required for professional concrete grinding.

Consequently, Diamond Tool Warehouse adds two important upgrades:

• A professional concrete-grinding dust shroud
• A heavy-duty professional grinding handle

The dust shroud surrounds the diamond cup wheel and helps collect concrete dust at its source. Meanwhile, the strong handle gives the operator greater control during edge grinding, floor preparation and coating removal.

As a result, this kit provides a more practical concrete-grinding setup than the standard grinder alone.

A diamond cup wheel, extraction hose and H-Class dust extractor are not included unless the product or order specifically states otherwise.

Powerful 2000W Brushless Motor

The Metabo WEVBA 20-125 uses a highly efficient Marathon brushless motor. Therefore, contractors receive strong grinding performance without the service needs of traditional carbon brushes.

Metabo combines its brushless design with internal cooling and motor dust protection. As a result, the grinder can handle demanding trade and industrial work while supporting a long service life.

Key motor specifications include:

• 2000W rated input power
• 1600W output power
• Brushless Marathon motor
• 3,300–11,000 RPM no-load speed
• 3.5Nm torque
• Constant speed under load
• Detachable motor dust filter

However, contractors must still clean the filter and follow Metabo’s maintenance instructions. Fine concrete dust can damage power tools if operators allow it to enter the motor.

Variable Speed for Different Grinding Tasks

The Metabo grinder uses Vario Tacho Constamatic electronics to provide an adjustable speed range of 3,300–11,000 RPM.

Therefore, operators can select a suitable speed for the connected grinding or polishing accessory. In addition, the electronics help maintain a more constant operating speed when the grinder comes under load.

Variable speed can help when working with:

• Diamond cup wheels
• Concrete grinding wheels
• Compatible polishing accessories
• Surface-preparation tooling
• Coating-removal tooling
• Abrasive discs approved for the grinder

Nevertheless, operators must follow the accessory manufacturer’s maximum speed rating. Never operate a diamond cup wheel or accessory above its marked maximum RPM.

Professional Dust Shroud

Diamond Tool Warehouse installs a professional dust shroud to help collect dust close to the grinding point.

When contractors connect the shroud to a suitable H-Class dust extractor, airflow draws concrete dust away from the cup wheel and through the extraction hose.

As a result, the shroud helps:

• Reduce airborne concrete dust
• Contain dust around the grinding area
• Improve visibility of the working surface
• Reduce job-site cleanup
• Support professional silica-dust controls
• Direct dust towards a compatible extractor

However, the dust shroud cannot control hazardous dust by itself. Contractors must connect it to a correctly sized H-Class dust extractor and use secure hoses and fittings.

Heavy-Duty Professional Handle

Concrete grinding creates torque, vibration and sideways movement. Therefore, operators need a stable two-handed grip.

The installed professional grinding handle gives the operator greater leverage and control. Consequently, it can make edge work, floor preparation and coating removal easier to manage.

The handle also helps operators maintain a flatter and more controlled grinding position. Nevertheless, operators must always hold the grinder with both hands and keep a firm, balanced stance.

Metabo M-Quick Disc Changes

The Metabo M-Quick system allows fast accessory changes without a separate pin spanner.

Operators can release the M-Quick flange nut at the touch of a button. Therefore, they can change compatible discs and cup wheels with less downtime.

Before changing any accessory:

1. Disconnect the grinder from power.
2. Allow the wheel to stop completely.
3. Check the accessory for cracks or damage.
4. Confirm the correct diameter, bore and RPM rating.
5. Fit the accessory according to Metabo’s instructions.
6. Check that the dust shroud and handle remain secure.

Anti-Vibration System

The WEVBA 20-125 features an integrated auto-balancer and a Metabo VibraTech side handle.

According to the listed Metabo specifications, the auto-balancer can reduce hand-arm vibration by up to 50%. In addition, lower vibration may help extend the service life of the grinder and compatible grinding wheels.

The kit also includes Diamond Tool Warehouse’s stronger professional grinding handle for concrete work.

However, anti-vibration features do not remove the risks linked to long-term tool use. Operators must still manage exposure time and follow workplace vibration-control procedures.

Grinder Safety Features

Metabo includes several safety systems to help protect the operator and machine:

• Fast mechanical brake
• Anti-kickback protection
• Electronic overload protection
• Soft start
• Restart protection
• Twist-resistant adjustable guard
• Low-vibration technology
• Detachable motor dust filter

For example, restart protection helps stop the grinder from starting unexpectedly after power returns. Meanwhile, anti-kickback control reacts when the accessory suddenly jams or catches.

These features support safer operation. However, they do not replace correct training, two-handed control, PPE or safe work methods.

Suitable Applications

The Metabo concrete grinding kit suits professional work including:

• Concrete edge grinding
• Concrete floor preparation
• High-spot reduction
• Surface levelling
• Epoxy coating removal
• Paint and sealer removal
• Adhesive and tile-glue removal
• Waterproofing removal
• Concrete repair preparation
• Residential garage preparation
• Commercial flooring projects
• Detailed grinding around walls and columns

The final performance will depend on the selected diamond cup wheel, surface hardness, coating type and dust extractor.

Therefore, contractors should match the cup-wheel bond and segment design to the concrete or material being removed.

Technical Specifications

Important Dust-Control Information

Concrete grinding can generate hazardous respirable crystalline silica dust. Therefore, contractors must use the grinder as part of a complete dust-control system.

A suitable system should include:

• The installed professional dust shroud
• A compatible H-Class dust extractor
• Correctly sized extraction hose and fittings
• Secure connections
• Regular filter checks
• Suitable respiratory protection
• Hearing and eye protection
• Safe cleanup methods

A general workshop vacuum may not provide suitable filtration for hazardous concrete dust. Consequently, contractors should use an H-Class extractor that meets the needs of the grinder, shroud and application.

Operating Safety

Before using the grinder:

• Read the Metabo operating instructions
• Check the power lead and grinder for damage
• Inspect the handle and shroud
• Confirm that all fittings remain secure
• Check the cup wheel for cracks or damage
• Confirm the accessory’s maximum RPM
• Connect the dust shroud to a suitable extractor
• Put on the required PPE

Required PPE may include:

• Safety glasses and a face shield
• Suitable hearing protection
• A correctly selected and fitted respirator
• Work gloves
• Protective footwear
• Suitable work clothing

Always hold the grinder with both hands. Furthermore, allow the machine to reach operating speed before contacting the surface.

Do not force or twist the cup wheel. Finally, disconnect the grinder from power before changing accessories, cleaning the filter or adjusting the shroud.
