Sanding Disc 3M 65335 Medium 115 mm Hook-and-Loop for Cleaning and Finishing

3M 65335 Medium 115 mm sanding disc with hook-and-loop attachment is designed for cleaning and finishing operations on a range of surfaces. The medium abrasive grade balances material removal and surface refinement for tasks such as paint preparation, rust removal and smoothing of wood, metal and composite substrates. The 115 mm diameter fits standard backing pads and is compatible with rotary and random orbital sanders; the hook-and-loop fastening enables quick change during multi-step workflows.

Advantages

The sanding disc offers consistent abrasive performance and even wear across the disc to maintain finish quality. Hook-and-loop attachment ensures fast and secure mounting and removal, reducing downtime between operations. Medium grit provides a balance between cutting speed and surface finish, which helps achieve efficient cleaning without excessive substrate damage. The 115 mm format provides good access in confined areas while remaining stable on common backing pads.

Suitable for

• Paint and coating surface preparation
• Rust and corrosion removal from metal surfaces
• Smoothing and refining wooden parts and edges
• Finishing composite components before bonding or painting
• General workshop sanding with 115 mm backing pads

Key specifications

• Abrasive grade: Medium grit
• Diameter: 115 mm
• Attachment type: Hook-and-loop (velcro) fastening
• Compatibility: Suitable for rotary and random orbital sanders that accept 115 mm discs
• Intended use: Cleaning and finishing of wood, metal, and composite materials

How to use

Select a 115 mm backing pad compatible with your sander and ensure the tool is powered off before fitting the disc. Align the hook-and-loop surfaces and press the disc firmly onto the backing pad to secure it. Start sanding at low-to-moderate speed and apply even pressure; increase speed or pressure only if controlled removal is required. Work progressively and inspect the surface frequently to avoid over-sanding. Replace the disc when abrasive performance declines or the backing is worn.

Usage recommendations

For optimal results, match the medium grit disc with coarser or finer grits in a multi-step process: begin with coarser abrasives for heavy material removal, then use this medium disc for smoothing and preparation before finishing with a fine grit. Use appropriate personal protective equipment such as eye protection, dust mask or respirator, and hearing protection. Avoid excessive heat buildup by using moderate speed and intermittent contact on heat-sensitive materials.
