Magnum 5/8" Coarse Aluminum Oxide Sanding Discs – 100 Pack

Tackle sanding, shaping, and surface cleanup in tight areas with Magnum 5/8" Coarse Aluminum Oxide Sanding Discs. These compact abrasive discs feature coarse aluminum oxide grit mounted on reinforced plastic, providing an aggressive abrasive surface for working on small components and confined areas.

Each disc has a snap-on/off brass center for quick attachment to the compatible BRS-279.00 mandrel. The compact 5/8" diameter provides excellent access where larger sanding discs are difficult to use, while the coarse abrasive is well suited to initial sanding and heavier surface refinement on non-precious metals.

Supplied in a box of 100 discs.

Specifications

Coarse Abrasive for Faster Material Removal

The coarse aluminum oxide abrasive makes ABR-175-03 the more aggressive choice when compared with the Fine version.

Use it for initial sanding, removing surface irregularities, smoothing rough areas, shaping, and other applications where faster material removal is more important than producing the final refined finish.

For work requiring a smoother surface, follow the coarse abrasive with a finer sanding disc as appropriate.

Compact 5/8" Diameter

The small 5/8" diameter makes these discs especially useful when working on small parts or reaching into areas where larger abrasive discs cannot easily fit.

Their compact size provides greater control over localized sanding and allows you to concentrate the abrasive action on the area that needs attention.

Reinforced Plastic Construction

The aluminum oxide abrasive is mounted on reinforced plastic for extended working life.

The reinforced construction supports the abrasive surface during rotary use while maintaining the compact disc format needed for detailed bench work.

Snap-On/Off Brass Center

Each disc incorporates a brass snap-on/off center designed to fit our BRS-279.00 mandrels.

The snap-on design makes changing abrasives fast and convenient. When a disc is worn, simply remove it from the compatible mandrel and snap on a fresh disc.

This is particularly convenient when moving through multiple discs during longer sanding or finishing jobs.

Coarse vs. Fine

Choose the abrasive grade according to the amount of material you need to remove.

Coarse – ABR-175-03
Best when you need more aggressive sanding, shaping, cleanup, or initial surface refinement.

Fine – ABR-175-01
Better suited to lighter sanding and refining the surface after more aggressive work.

Using the Coarse and Fine versions together provides a simple progression from initial sanding to a more refined surface.

For Non-Precious Metals

These discs are recommended for sanding and polishing non-precious metals.

The coarse abrasive makes them particularly useful for initial surface preparation and areas requiring more material removal before progressing to finer abrasives or polishing steps.
