Grinding wheel GRAPHITE 57H839 for rotary tool, wood, Ø115 mm, 54 g, 1 pc

GRAPHITE 57H839 is a grinding wheel for rotary tools designed primarily for working with wood. The abrasive disc has a diameter of 115 mm and a net weight of 54 g. Supplied as a single piece per pack, this grinding wheel is intended for sanding, shaping and finishing wooden surfaces and edges where a rotating abrasive disc is required. The product uses a close-coated abrasive layer on an X-cloth backing delivering consistent abrasion and improved durability for mechanical grinding tasks.

Advantages

The close coating (100% of the paper surface covered with abrasive grain) ensures even material removal and higher processing accuracy compared with open-coated discs. X-cloth backing increases mechanical strength and tear resistance during use on rotary tools. The construction and leaf arrangement are designed to provide higher efficiency and stable performance when sanding and shaping wood, while the compact single-piece supply simplifies replacement and inventory management.

Suitable for

• Sanding and smoothing wooden surfaces and edges
• Shaping wood profiles and contours
• Surface preparation before finishing or painting
• Light-duty material removal on wooden parts

How to use

Install the grinding wheel on a compatible rotary tool following the tool manufacturer's instructions and ensuring proper flanges and fastening. Check that the tool is powered off and unplugged when mounting. Use appropriate rotational speed recommended for a 115 mm abrasive disc and avoid exceeding the maximum speed rating of the rotary tool. Apply light to moderate pressure and move the disc evenly across the workpiece to avoid gouging; allow the abrasive to do the cutting. Replace the disc when wear reduces effectiveness or if any damage to the backing or abrasive layer is visible.

Usage recommendations

For safe and effective operation, wear suitable personal protective equipment including eye protection, dust mask, hearing protection and gloves. Use dust extraction or work in a well-ventilated area when sanding wood. Test on a scrap piece to verify finish and speed settings before working on the final surface. Do not use the disc on materials or at speeds beyond the specified limits.
