Flap disc X-Treme HD Made of a very strong and newly developed polyester fabric coated with the latest generation Norzon abrasive. The new flap disc contains extra long abrasive cloth flaps, which give a significantly longer service life. This also gives more effective grinding, making X-Treme Heavy Duty suitable for e.g. edge chamfering and rounding. The flap disc is highly resistant to wear and tear, which also contributes to longer life. The abrasive used is intended for machining iron, steel and stainless and provides an extra high removal rate in a short period of time. X-Treme HD is intended for use in angle grinders and has a convex support plate made of fibre glass.
