PFERD Flap Wheel - Unmounted Type - Aluminium Oxide (A-COOL - Reduced Heat) FR 16550 A-COOL 60 Grit

Flap Wheel - Unmounted Type - Aluminium Oxide (A-COOL - Reduced Heat) FR 16550 A-COOL 60 Grit

Designed for work on stainless steel (INOX) and high-temperature-resistant alloys. Active grinding additives in the coating substantially improve stock removal, prevent clogging and result in cooler grinding. Unmounted flap wheels FR 15050 and FR 16550 comply with ISO 5429.

Abrasive: Aluminium oxide A-COOL

The coated abrasive flaps are arranged radially around the tool axis in a fan-type configuration. Due to their flexibility, they adapt ideally to the contours of the workpiece. The abrasive grit is embedded in a resinoid bond on the strong, flexible backing cloth. Unmounted flap wheels are designated "Flap
Wheels" according to ISO 5429.

Recommendations for use:
- Unmounted flap wheels achieve their best performance at a recommended cutting speed of 15Ð30 m/s. This provides an ideal compromise between stock removal, surface quality, thermal load on the workpiece and tool wear.
- Flexible shafts, straight grinders and grinding blocks can be used as tool drives
- The drive power output required for tool drives is 1,000Ð1,500 watts
- Use grinding oil that is suitable for the material in order to significantly increase the tool life and the abrasive performance of the tools.

Advantages:
- High flexibility
- High stock removal due to the aggressive coated abrasive
- Carrier material wears off uniformly and without residue on the workpiece surface, meaning that sharp abrasive grain is exposed at all times
- Due to the special mounting system, the face of the unmounted flap wheels can be used to work very close to edges and in corners

Safety notes:
- As a rule, unmounted flap wheels should be used with the appropriate clamping flanges
- The maximum permitted peripheral speed is determined as follows:
- Unmounted flap wheels = 50 m/s
- Unmounted flap wheels for angle grinders = 80 m/s
- For safety reasons, it is imperative to remain within the stated maximum permitted rotational speed at all times
