Description

The DEWALT DW8382 6-Inch x 7/8-Inch Type 29 HP Flap Disc is a high-performance abrasive built for grinding, blending, and finishing metal. The Type 29 (T29) shape offers a broader contact surface and a steeper working angle than flat flap discs, making it ideal for light-to-medium stock removal and blending on flat and contoured surfaces. With 80 grit, it’s a versatile choice for cleaning up welds, removing rust, and smoothing steel.

DEWALT DW8382 Type 29 Flap Disc: 80 Grit Grinding and Blending

This disc’s 6-inch diameter and 7/8-inch arbor fit standard large angle grinders. The flexible abrasive flaps wear evenly, exposing fresh grain as they go, which extends disc life and keeps a consistent finish. The fiber backing adds durability, and the disc is rated for high-RPM work when used on compatible grinders.

Choosing the Right Flap Disc Size and Grit

For most steel and stainless steel work, an 80 grit disc is the go-to between coarse and fine finishing. It removes weld splatter and rust quickly while leaving a clean surface that can be brushed or painted. If you need more aggressive stock removal, step down to a 40 or 60 grit; for a smoother satin finish, move up to 120 grit.

Safety and Setup

Always use a proper guard, eye protection, and the correct backing pad for your grinder. Check that your grinder’s maximum RPM exceeds the disc rating and that the arbor is exactly 7/8-inch before mounting. Inspect the disc for damage before each use.

Product Details

Get More from Your Flap Disc

The DEWALT DW8382 is designed for pros who need consistent performance and long life. Unlike traditional grinding wheels, flap discs deliver both grinding and finishing in one step, saving you time and reducing wheel changes.

Type 29 Explained

The angled shape of a Type 29 disc lets you use it at a lower angle for stock removal and blend while still covering a broad area. It’s the go-to choice for beveling, weld grinding, and edge chamfering because the shape promotes faster cutting without gouging.

Abrasive Selection Tips

Lower grit numbers are coarser and cut faster; higher grits produce finer finishes. Start with 80 grit to balance material removal with surface quality. For extra-long life, let the flaps do the work and use moderate pressure.

Frequently Asked Questions

Will this flap disc fit a 4.5-inch angle grinder?

No, this is a 6-inch disc. It requires a grinder that supports 6-inch discs with a 7/8-inch arbor.

How many discs are in this listing?

This listing includes 1 flap disc.

Can I use this disc on stainless steel?

Yes, 80 grit aluminum oxide works on stainless steel. Avoid using the same disc on steel first to prevent contamination.

What is the difference between Type 27 and Type 29?

Type 29 flap discs are angled to provide a more aggressive grinding angle and better material removal on curved or contoured surfaces. Type 27 discs are flatter and better suited for flat-face blending.

Good value

I've used these on my angle grinder for metal fabrication. They last a long time and don't load up. Good value.

Ideal for blending welds

I've been welding since the early eighties, and flap discs have changed how we finish metal. This 80-grit disc is ideal for blending welds and removing rust. It's aggressive enough to save time, yet it leaves a surprisingly smooth finish. The Type 29 shape allows for better contact. I've used cheaper brands, but they wear out fast. This one lasts three times as long. It's a worthwhile investment for any serious metalworker.

Used it to clean up some steel. It worked quickly and didn't wear down as fast as I expected. Would buy again.
