Buying Guide

Match disc type to material

Choose aluminum-oxide or bonded abrasive discs for steel and stainless; diamond or turbo-segment wheels are designed for concrete, masonry and other hard materials

Confirm wheel size and arbor fit

Pick discs that match your angle grinder's diameter (e.g., 4-1/2" or 7") and arbor hole (commonly 7/8") to ensure safe mounting and proper clearance

Consider segment style for cutting speed

Turbo segments and cup wheels remove material faster on concrete and masonry, while flat grinding wheels give smoother results on metal

Check grit and bond for finish

Lower grits remove material quickly but leave rougher finishes; finer grits and harder bonds last longer and produce smoother surfaces

Evaluate pack size and value

Higher-count packs are cost-effective for frequent use, while single or smaller packs suit occasional projects; compare review volume and ratings to gauge consistency
