💡 Why are zirconia flap discs handy for stripping heavy mill scale off structural steel?

- Zirconia alumina compounds fracture under load to expose fresh sharp edges that slice through weld spatter quickly. - They maintain consistent cutting force across thick plate prep or thin sheet metal straightening jobs without burning out. - Operators get quicker debris clearance and cooler running speeds which protects bearing seals on handheld angle grinders. ✝️
