Sanding Disc 3M 65336 Medium 125 mm Hook-and-Loop for Cleaning and Finishing

3M 65336 Sanding Disc Medium 125 mm with hook-and-loop backing is designed for cleaning and finishing operations on metal and composite surfaces. The 125 mm diameter fits standard orbital and random-orbit sanders and the medium abrasive grade provides balanced material removal with surface refinement. The hook-and-loop attachment enables quick disc changes and stable hold during use, supporting consistent results in preparation before painting, coating, or welding touch-up work.

Advantages

The sanding disc delivers uniform medium-abrasion performance across the working area while maintaining good edge durability. The hook-and-loop backing allows fast replacement and secure mounting on compatible sanding pads, reducing downtime. Abrasive formulation and disc construction are optimized for cleaning contaminants, removing light corrosion and paint residues, and producing a finish suitable for subsequent coating processes. Its 125 mm size offers a balance between coverage and control for workshop and bodyshop tasks.

Suitable for

• Surface preparation of metal and composite panels
• Cleaning and light removal of rust, paint, and adhesives
• Finishing before primer, paint or coating application
• Detail sanding in automotive bodyshops and small workshops
• Use with compatible 125 mm orbital or random-orbit sanders

Key specifications

• Disc diameter: 125 mm
• Abrasive grade: Medium grit
• Attachment type: Hook-and-loop backing for quick change
• Intended materials: Metals and composite substrates
• Primary applications: Cleaning, light material removal, finishing

How to use

Secure a compatible 125 mm sanding pad on your orbital or random-orbit sander, align the hook-and-loop backing of the disc with the pad, and press firmly to attach. Start sanding at low speed to verify contact and adjust pressure to maintain even abrasive engagement; avoid excessive force that can cause premature wear or surface damage. Move the sander in overlapping passes and check the surface frequently to achieve the desired level of cleaning or finish. Replace the disc when abrasive performance decreases or the backing shows wear.

Usage recommendations

Use appropriate personal protective equipment including respiratory protection, eye protection and gloves. Test on an inconspicuous area before full application to confirm suitability for the substrate and process. For best results on painted surfaces, follow with finer abrasives as required by the coating system.
