Buying Guide

Match arbor and wheel size

Confirm your angle grinder or floor grinder arbor (5/8-11 or 5/8) and wheel diameter (4.5" or 7") to ensure a safe fit

Choose grit for material and speed

Use coarser grits (30–40) for aggressive coating removal and finer grits for leveling or finish work

Pick segment style for task

Turbo or segmented diamond rims improve stock removal on paint and epoxy, while continuous rims suit finer edge work

Consider bond hardness

Medium bond wheels balance life and cutting rate for varied concrete conditions; softer bonds wear faster on hard substrates

Check compatibility with concrete prep

Steel core construction and multiple diamond segments are preferable for heavy coating removal and surface prep
