EZARC 40-Grit Zirconia Flap Discs, Type 29, 4.5-Inch, 12 Pack

A fine abrasive is suited to lighter finishing, while a coarse disc is designed for more substantial sanding and stock removal. These EZARC 40-grit flap discs use blue zirconia grains and a high-density layout of 90 flaps per disc. The Type 29 bevel supports work on surfaces, edges, and welded seams. Need one abrasive setup for sanding, rust removal, and deburring? This 12-pack covers those jobs with a disc made for an angle grinder.

The coarse 40 grit is intended for heavier stock removal, making the discs useful for sanding, grinding, and removing rust or weld reinforcement. They can also be used for deburring, blending, polishing, and finishing. The Type 29 angled profile offers access for edge and corner grinding as well as broader surface work, so one disc format can serve several stages of metal preparation.

Practical tips

Use these discs with an angle grinder and keep the tool’s speed within the disc’s 13,300 rpm maximum. For welded seams, the recommended working angle is 15 to 20 degrees. On a practical project, that setup can help address a weld bead and then work across nearby metal for sanding or deburring. The discs are also listed for wood, so the same coarse abrasive format can be considered for wood sanding when the task calls for substantial material removal.

Choose this 40-grit format when the job calls for a coarse abrasive and broad material removal, a finer-grit approach is more suited to lighter finishing. Buyers often praise the wheels’ effectiveness across applications, including heavy sanding on auto bodies. Feedback on how long they last is mixed, so actual wear can vary with the material and the work being done.

Box contents

The pack contains 12 EZARC Type 29 flap discs. Keeping multiple discs on hand is useful for a run of related grinding or sanding tasks, with the same 4.5-inch diameter, 7/8-inch arbor, and 40-grit zirconia abrasive across the pack.

Final verdict

For metalworkers, repair projects, and other users who need a coarse angle-grinder abrasive for sanding, rust removal, weld work, or deburring, these EZARC discs bring several practical details together: a Type 29 profile, 90 zirconia flaps per disc, and a 12-disc pack. They’re a great fit if your work calls for a versatile 40-grit wheel for both surface and edge tasks, with the stated speed and arbor size matching your grinder setup.
