Weiler 51514 Hook Loop Abrasive Disc 4.5 in Aluminum Oxide Coarse

Product Description

The WEILER 51514 is a hook and loop non-woven abrasive disc designed for surface preparation, blending, and finishing on metal substrates. The disc measures 4.5 inches in diameter and features aluminum oxide abrasive in a coarse grade, making it well-suited for aggressive material removal and surface conditioning tasks. The non-woven construction provides consistent scratch patterns and resists loading on soft metals. At 0.08 pounds, it mounts quickly to any compatible hook and loop backing pad and is rated to a maximum of 13,000 RPM. Fabricators, maintenance technicians, and metalworkers are the primary installers for this type of consumable.

This disc is used for deburring, surface blending, and weld prep on aluminum and stainless steel. The coarse grade cuts efficiently on both materials without the glazing common to bonded abrasives. It is appropriate for bench grinding setups and angle grinder applications where a hook and loop fastening system is already in place. Typical use cases include shop fabrication environments, field maintenance on stainless process equipment, and light stock removal on aluminum extrusions or sheet goods.

Key Features

• Aluminum oxide abrasive in coarse grade for fast cutting on metal
• Non-woven disc construction resists loading and delivers consistent scratch patterns
• Hook and loop attachment for tool-free disc changes on compatible backing pads
• Rated to 13,000 RPM for use with standard angle grinders
• Suitable for aluminum and stainless steel applications
• No vacuum holes — compatible with solid backing pad setups

Compatibility

Designed for use on aluminum and stainless steel surfaces. Requires a hook and loop backing pad of matching 4.5-inch diameter. No vacuum hole pattern is present, so a solid-face backing pad is required.

Installation Notes

This disc is installed by trade professionals and experienced fabricators familiar with angle grinder safety. Before mounting, confirm the tool's free-speed RPM does not exceed 13,000 RPM. Inspect the backing pad for wear or damage before attaching the disc, and ensure the hook and loop surface is clean and free of debris for secure adhesion. Always use appropriate eye protection, hearing protection, and gloves when operating abrasive discs on powered tools.
