## Overview

Benchmark Abrasives 4-1/2" x 7/8" Type 29 flap discs deliver industrial-strength grinding and finishing with premium European zirconia cloth. Designed for angle grinders, this 100-pack of 80 grit discs offers aggressive stock removal, long-lasting durability, and consistent performance across multiple heavy-duty applications, all while exceeding ANSI and EU quality standards.

## Description

Flap discs are used in heavy stock removal, usually weld removal. They outperform Resin Fiber Discs due to their increased lifetime. Resin Fiber discs are only two dimensional, once the abrasive surface wears down the product is finished. To achieve a finish equivalent to a resin fiber disc always use a flap disc one grit coarser. E.g. if the operator is running a 60 grit resin fiber disc try a 40 or 50 grit flap disc.

## Features
