What is the DEDRA H12H0400, and why should you choose the G400 diamond polishing pad??

DEDRA H12H0400 is a pad, or polishing disc, whose working surface contains diamond abrasive.Diamond is a highly valued material in abrasive tools due to its high hardness, which allows it to effectively cut porcelain stoneware, granite, marble, stone, glazed tiles, and terracotta.This product is intended for dry operation, which makes it more convenient to use in many installation and renovation situations.

Graded disc 400 is primarily used for smoothing and improving surface quality after previous processing stages.It can be used to finish the edges of porcelain tiles after cutting, to smooth the edges of stone window sills, to gently polish marble elements, or to prepare granite surfaces for further polishing.

This product is a practical choice when consistent results, good control over the work process, and an attractive finish are important.Compared to standard abrasives, a diamond disc performs better on hard surfaces that require a tool capable of withstanding heavy-duty use.

• For hard materials: designed for porcelain tile, granite, marble, stone, glazed tile, and terracotta.
• For finishing work: helps achieve a smoother surface and minimize the visibility of cutting or sanding marks.

Where is the DEDRA H12H0400 125 mm polishing disc mounted??

DEDRA H12H0400 is mounted on a suitable mounting plate or polishing pad holder suited for a 125 mm diameter and the power tool being used.Discs of this type are most commonly used with polishing machines, grinders, or polishers equipped with the appropriate mounting accessories.Before starting work, make sure that the handle, plate, and device are compatible with the pad and that the tool is designed for polishing the specific material.

Information “Hole diameter: N/A” means that for this type of pad, it is important to select the correct mounting system rather than a traditional mounting hole as found on standard cutting discs.This makes the pad ideal for finishing work, where smooth operation, even pressure, and precise control are essential.

In everyday use, the disc can be used, among other things, to grind the edges of tiles after cutting, to smooth the visible edges of countertops or window sills, and during renovation work on stone elements.For best results, it’s a good idea to use the correct order of grit sizes, starting with lower grits for larger irregularities and then moving on to higher grits to achieve a smoother finish.
