Angle grinder accessory Dedra HP2107E — backing/flange plate, 25 cm diameter, 1 pc

Dedra HP2107E backing/flange plate with a 25 cm (250 mm) diameter is a replacement accessory for compatible angle grinders. It provides a flat, stable support surface for grinding, sanding or polishing discs and is supplied as a single unit. The plate is intended for use with Dedra angle grinders and other tools that accept the same mounting dimensions, allowing secure disc attachment and uniform pressure distribution during operation.

Advantages

The backing plate offers a large 250 mm contact area that helps stabilize discs and reduce vibration during work. Manufactured to match common mounting standards for compatible grinders, it enables quick replacement and consistent disc alignment. The single-piece supply makes it easy to stock or replace when maintenance is required, and its rigid construction supports even pressure across the disc for more predictable results.

Suitable for

• Grinding metal surfaces with abrasive discs
• Sanding and surface preparation on wood or composites
• Polishing large surfaces with polishing pads
• Replacing worn or damaged backing plates on compatible angle grinders

Key specifications

• Diameter: 250 mm (25 cm)
• Type: backing / flange plate for angle grinder discs
• Quantity: 1 piece per pack
• Compatibility: designed for angle grinders with matching mounting dimensions

How to use

Before installation, ensure the angle grinder is disconnected from power. Remove the existing backing plate following the tool manufacturer's instructions, align the replacement backing plate with the spindle and mounting threads or flange, then tighten securely to the recommended torque. Mount the chosen grinding, sanding or polishing disc onto the plate, checking that the disc sits flat and is centered. Reconnect power and perform a brief test run at low speed to confirm secure attachment and smooth rotation before normal operation.

Usage recommendations

Use discs and pads appropriate for a 250 mm backing plate and verify that the grinder's spindle size and mounting pattern match the plate. Inspect the plate and disc for damage before each use, avoid side-loading the plate beyond intended application, and follow the angle grinder manufacturer's safety guidance including appropriate personal protective equipment.
