Zoro Select Type 29 Flap Disc 4 Inch

This Zoro Select flap disc is a coated abrasive tool built for angle grinders with a 5/8 inch unthreaded arbor. It suits metal fabrication, weld blending and surface preparation where a medium-grade zirconia alumina abrasive is required. The Type 29 angled face gives aggressive stock removal on flat and contoured workpieces.

60 Grit Zirconia Alumina Capacity

The 60 grit zirconia alumina flaps deliver consistent cutting action on steel and stainless steel, maintaining material removal rate through the disc life. Medium density and X-weight fiberglass backing provide enough rigidity for heavy grinding while still conforming to curved surfaces. Maximum operating speed is 15,300 RPM, so the disc must only be used on grinders rated at or below that speed.

Fiberglass Backing and 5/8 Inch Arbor

The fiberglass backing plate absorbs vibration and resists heat buildup during extended grinding sessions. An unthreaded 5/8 inch centre hole fits directly onto standard angle-grinder spindles without additional adapters. Builders needing threaded hubs, finer finishing grits or larger diameter discs will need a different product.

Questions about this item

Will this 4 in Type 29 flap disc fit the 5/8 in arbor on my older angle grinder?

Yes, the unthreaded 5/8 in hole matches the standard arbor size on most 4 in grinders.

How can I confirm the disc is running true after mounting it?

Run the grinder at no load; the disc should spin without wobble up to the 15,300 RPM maximum speed.

Does the box include a backing pad or mounting nut, or must I buy them separately?

The disc has a built-in fiberglass backing plate, so no separate backing pad is needed; a compatible 5/8 in flange nut is required if your grinder does not already have one.
