Buying Guide

Match disc grit to bevel needs

Use coarse grits (36–60) for heavy material removal and higher grits for blending and finishing on bevels

Choose the right abrasive type

Zirconia offers fast cut and long life for steel beveling, while aluminum oxide is better for lighter-duty tasks

Confirm diameter and arbor

Select 4.5 inch discs with a 7/8 inch (22.23 mm) arbor to fit common angle grinders used for beveling

Consider disc shape for beveling

T29 flat flap discs provide consistent contact for edge bevels; angled or conical designs may suit more contoured bevels

Buy by pack size for value

Large 100-count packs lower per-disc cost for frequent use but assess storage and shelf life before bulk buying
