Diamond dressing tool for grinding wheels GEKO G78289 (125 mm)

The Diamond dressing tool for grinding wheels GEKO G78289 (125 mm) is designed to restore the cutting profile of abrasives and maintain consistent grinding performance. Intended for use with bench grinders and stationary grinding machines with a 125 mm wheel diameter, this dressing tool removes glazing, embedded debris and unevenness from the wheel surface to improve cutting efficiency and surface finish. The tool is compatible with typical workshop and metalworking environments where regular wheel maintenance is required.

Advantages

This diamond dressing tool provides precise truing and dressing of grinding wheels, extending wheel life by exposing fresh abrasive grains and removing clogged material. Its diamond cutting element ensures consistent dressing results and reduces downtime by enabling quick restoration of wheel geometry. The compact design is suitable for use on standard 125 mm wheels and supports improved surface quality and repeatable grinding performance.

Suitable for

• Restoring profile and concentricity of 125 mm grinding wheels
• Removing glazing, embedded contaminants and loading from abrasive surfaces
• Sharpening tools and maintaining cutting edges in metalworking shops
• Routine maintenance of bench grinders and small stationary grinding machines

Key specifications

• Tool type: diamond dressing tool for grinding wheels
• Compatible wheel diameter: 125 mm
• Function: truing, dressing and deglazing of abrasive wheels
• Application areas: metalworking, tool sharpening, workshop maintenance
• Design feature: diamond cutting element for consistent material removal

How to use

Secure the grinder or grinding machine and ensure the wheel is brought up to operating speed before dressing. With the machine switched on and the wheel rotating at the recommended speed, apply the diamond dressing tool gently to the wheel surface, moving it across the face to restore the desired profile and remove glazing. Use light, controlled passes rather than heavy pressure, and check the wheel periodically to avoid over-dressing. After truing, stop the machine and inspect the wheel for uniformity and balance before resuming grinding work.

Usage recommendations

Prior to dressing, verify the grinder's safety guards are in place and wear appropriate personal protective equipment such as safety glasses and a dust mask. Avoid using excessive force; multiple light passes yield better results and reduce the risk of wheel damage. For heavily loaded wheels, start with small, incremental dressing passes and inspect the wheel balance after truing. Store the dressing tool in a dry place and keep the diamond element free of oil or grease to maintain performance.
