Pferd Unmounted Flap Wheel

• Flap Wheel - Unmounted Type - Aluminium Oxide
• 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.
• For universal applications from coarse to fine grinding.

• Unmounted flap wheels achieve their best performance at a recommended cutting speed of 30 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 1,000̐1,500 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
