GRENPRO 110-Piece 5-Inch Sanding Discs, 8-Hole, 60–2000 Grit

Some projects need coarse abrasion to strip or shape a surface, others call for finer grits to smooth and polish. This GRENPRO set brings both stages together in one assortment. Printed grit numbers make it easier to find the grade you need as the work changes.

What it works with

The 5-inch hook-and-loop backing is designed for random orbital sanders, die grinders, air grinders, and electric drills. The discs’ eight holes are intended to align with dust collection ports on orbital sanders, helping sanding dust move through the tool’s extraction system. For a secure fit and effective collection, line up the disc with the tool’s backing pad and dust ports before sanding.

The abrasive assortment covers wood, metal, plastic, leather, stone, and glass. That range is useful when a workshop handles different materials and projects, from woodworking and metal cleanup to polishing tasks. As with any abrasive, select a grit suited to the surface and the stage of work rather than using one grade for every job.

Tips for day-to-day use

Start with a coarser grade for heavier stripping or rough grinding, then move through progressively finer grits as the surface becomes smoother. The set’s 60-grit discs are suited to heavy removal, while the 120-to-600 range supports medium finishing. The finer 800-to-2,000 grits are intended for polishing work. Printed grit numbers on the backing help identify discs between steps and make it simpler to put the right grade back in its place.

The red aluminum oxide abrasive has a clog-resistant coating, designed to reduce dust buildup and grit shedding during dry sanding. Keep the work area organized by separating used discs by grit, and check that the hook-and-loop surface is seated evenly on the tool before starting. When sanding with an orbital sander, align the eight openings so dust can reach the collection ports.

Buying individual discs in a single grit can suit a project with one consistent sanding stage. This mixed set is a more flexible approach when a task moves from material removal through finishing, or when several materials and surface treatments are part of the same workspace. Its broad grit range lets you choose a suitable disc for each stage without treating coarse and fine sanding as interchangeable.

Buying verdict

For DIY users and professionals who want a range of abrasive grades in a single 5-inch format, this GRENPRO assortment provides a practical progression from 60-grit stripping to fine polishing. The printed backing, hook-and-loop attachment, and eight-hole layout support clear grit selection and use with compatible tools. It’s a useful fit for varied dry-sanding jobs across wood, metal, plastic, leather, stone, and glass.
