Flap disc for aggressive stock removal

This 6 inch Type 29 flap disc uses zirconia alumina on a phenolic backing for coarse grinding on metal. The 40 grit surface cuts quickly while the angled flaps maintain consistent contact across curved or flat workpieces. Ten discs per box support extended shop use.

Phenolic backing with unthreaded 7/8 inch arbor

The rigid phenolic plate resists flex under heavy pressure and mounts directly on standard angle grinders without adapters. Unthreaded hole design speeds disc changes between jobs. Standard density rating balances material removal rate with surface finish control.

Maximum operating speed 10200 RPM

This speed limit defines the grinder compatibility window for safe operation. Exceeding the rated RPM risks disc failure and operator injury. Verify your tool specification matches before mounting any disc from the box.

Questions about this item

What does the Type 29 profile mean for how this flap disc contacts the workpiece?

Type 29 gives an angled face that works best at a shallow angle to the workpiece for aggressive stock removal.

What arbor size and backing material does this 6-inch disc need to mount securely?

It has a 7/8-inch unthreaded arbor hole and a phenolic backing plate for standard angle-grinder spindles.

How is this flap disc installed and what common step should be avoided?

Slide the disc onto the grinder spindle, tighten the flange nut, and do not over-tighten or the phenolic backing can crack.
