## Overview

The NEIKO 11108A 10-pack flap discs feature 4.5-inch aluminum oxide abrasive wheels with 80 grit for medium stock removal and surface finishing. Designed with a flat Type 27 profile and a 7/8-inch arbor, these discs operate up to 13,300 RPM and include a fiberglass backing plate to reduce vibration and smearing. Ideal for metal, wood, plastic, and fiberglass, they deliver professional-grade grinding, blending, and deburring for industrial and DIY applications.

## Description

The Neiko 11108A 80 grit Aluminum Oxide 4.5” Flap Disc is a T27 flat disc outfitted with a 7/8” arbor and are packed in a 10-piece set. Flap discs are a multi-functional abrasive which can perform stock removal and surface finishing at the same time. These AO flapper wheels are best used on ferrous and non-ferrous metals like stainless steel, carbon steel, tool steel, nickel alloy, aluminum, titanium, cast iron and welds. AO flap discs can be used on other materials like rubber, plastic, fiberglass, and wood, but Zirconia would be a good alternative if longer life, faster cut, and higher heat and pressure are concerns. Abrasive flap discs are commonly used in welding, machining, manufacturing, heavy-duty equipment work, and industrial maintenance. Can be used to remove paint and rust, cleaning flashing, edge grinding and chamfering, deburring, blending of weld seams and materials, stock removal, sharpening, shaping, contouring, and smoothing of various materials, surface preparation and surface finishing, and the finer grits can be used for shining and polishing. Choose coarse 40 grit when removing more material or initial grinding, flattening, or shaping. Choose medium 60 or 80 grit for surface preparation, cleaning, and deburring. Choose fine 120 grit for blending or creating a semi-polished surface.

Review: Solid Pad - I recently purchased the NEIKO 11142A Zirconia Flap Discs, and I have to say, they exceeded my expectations. The quality of these discs is impressive—they're durable and hold up well under high pressure and heat. I used them for grinding and sanding metal, and they performed flawlessly, removing material quickly and leaving a smooth finish. The angled Type 29 design is particularly useful for shaping edges and grinding contours. It feels like the discs were designed with precision in mind. The fiberglass backing plate is another great feature—it absorbs vibrations and prevents smearing, which makes the whole process smoother and more efficient. Overall, these flap discs are a fantastic value for the price. If you're looking for reliable and high-performing discs for your angle grinder, I highly recommend giving these a try.
Review: A Descent Quality Flapper Disc - These are descent quality discs. So far I've only used one, but no issues. Some reviewers mention it making blue dust which made me hesitant to buy these. I did not experience that at all, just normal metal dust. They have good abrasive qualities and cut down weld material quickly, slightly above average for a flapper. Probably not as long lasting as some more expensive discs but wearing reasonably well. I think they are a good buy and get the job done.

## Features

- PREMIUM QUALITY: These flat flap discs, also known as cut off wheels 4 1/2 inch, are constructed with industrial grade premium aluminum oxide abrasive for strength, durability, and fine finishes.

## Questions & Answers

**Q: will these disks work to sand wood?**
A: i have been using the 80 grit disc on wood for three years , i use them to sculpt live edge lumber for furniture. they work great just dont over use them when they are worn out change them or they will burn the wood. they are not ment to finish sand and will gouge the wood if you are not careful.

**Q: Will these flap disk grinders fit black and decker angle grinders?**
A: Hi Steve.  These are generic and should fit any 4 1/2" angle grinders.  They work very well at removing paint and rust without removing a lot of metal

**Q: The chrome on my runner boards is bubbling and chipping. Will this work to sand the remaining chrome off and prep for Spray on bed liner on them?**
A: yes, these will sand anything, ive used them on wood,metal, paint and varnish so far, the paint and varnish clog them up pretty fast tho

**Q: Where are they made?**
A: China

### ⭐⭐⭐⭐⭐ Flap disc
*by J***E on September 7, 2025*

These flap discs are excellent quality. They cut smoothly, last longer than the cheaper discs I’ve used, and don’t wear down quickly even on tougher metals. Great value for the price, and they fit my grinder perfectly. Highly recommend for anyone doing metal fabrication or welding work.
