Abrasive Grinding Block 89×125×25 mm, Grit P80, No name (MPN 337847)

Abrasive Grinding Block 89×125×25 mm with grit P80 is a rectangular manual sanding tool designed for medium-coarse surface preparation. The compact block form provides a stable handhold and even wear across the abrasive surface, making it suitable for tasks that require controlled pressure and consistent removal of material. This grinding block is intended for manual use on wood, metal, plaster and painted surfaces where moderate material removal, leveling or rough shaping is needed.

Advantages

The block's dimensions (89×125×25 mm) offer a balance between surface coverage and maneuverability, allowing precise control in corners and flat areas. Grit P80 delivers medium-coarse abrasive action that efficiently removes old paint, rust and uneven plaster while still permitting a degree of surface smoothing. The rigid rectangular body ensures uniform contact with the workpiece, reducing finger fatigue and promoting even abrasive wear for predictable performance during sanding sessions.

Suitable for (tasks / use cases)

• Manual removal of paint and varnish from wood and metal surfaces
• Rust and oxidation removal on metal parts prior to priming or painting
• Leveling and rough shaping of plaster, filler and putty
• Surface preparation before sanding with finer abrasives or applying coatings
• Carpentry and renovation tasks requiring controlled abrasion

Key specifications

• Dimensions: 89 × 125 × 25 mm
• Abrasive grit: P80 (medium-coarse)
• Shape: rectangular block for hand sanding
• Intended use: manual sanding and surface preparation on wood, metal and plaster

How to use

Hold the grinding block with a comfortable grip and apply even pressure while moving it along the surface in the direction appropriate for the material. For painted or rusty metal, begin with steady strokes to remove loose material, then inspect the surface and repeat until the desired level of removal is achieved. On wood and plaster, use controlled passes to level irregularities without gouging; switch to finer abrasives for finishing. Replace the block or abrasive surface when wear reduces effectiveness to maintain consistent results.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, dust mask and gloves. Test on a small inconspicuous area first to verify the effect on the substrate. For best results combine the P80 block with progressively finer abrasives when preparing surfaces for painting or finishing.
