Buying Guide

Match abrasive material to task

Zirconia and zirconium-oxide discs suit heavy stock removal and metal work, while aluminium-oxide works well for general-purpose grinding and light finishing

Choose the right grit

Lower grits (e.g., 80) remove material faster; higher grits (e.g., 120) leave a finer finish—pick grit based on whether you need rapid cutting or smoother results

Pick compatible mounting

Confirm shank or arbor size (1/4" shank vs 7/8" arbor) so wheels fit your drill, die grinder, or angle grinder without adapters

Consider wheel diameter and thickness

Larger diameters (around 7") cover more surface area faster; smaller 1–2" wheels reach tight spots and edges for detail work

Balance pack size vs. value

Multipacks (dozens in a set) lower per-wheel cost for frequent use, while smaller packs or single discs are better for occasional, specific tasks
