Abrasive Flap Cylinder KLINGSPOR Faecherschleifer 50x20mm K40 with 6mm Shank (MPN 12996)

Abrasive flap cylinder KLINGSPOR Faecherschleifer 50x20mm K40 with a 6mm shank is a rotary abrasive tool designed for use with die grinders and rotary tools. The cylinder shape combines overlapping abrasive flaps arranged around a central core to provide aggressive stock removal while maintaining a consistent contact surface. With K40 grit it is intended for coarse material removal tasks such as deburring, rounding sharp edges and preparing rough surfaces on a range of metals and other hard materials. The tool is supplied in a pack quantity useful for workshop and production environments where frequent tool changes are required.

Advantages

The flap construction ensures fast material removal and a uniform finish as the flaps wear, reducing the risk of gouging. The coarse K40 abrasive provides efficient cutting action on welded seams, burrs and oxidized layers. A 6 mm shank enables compatibility with most standard collets on handheld die grinders and rotary tools. The compact 50x20 mm dimensions make the cylinder suitable for access to confined areas while offering a stable working surface.

Suitable for

• Deburring welded joints and cutting edges
• Edge rounding and chamfering of metal parts
• Surface preparation before welding or coating
• Removal of rust, scale and oxidation on steel
• General-purpose metal surface conditioning

Key specifications

• Shape: cylindrical flap wheel (flap cylinder)
• Dimensions: 50 mm diameter x 20 mm width
• Abrasive grit: coarse (K40)
• Shank diameter: 6 mm
• Pack quantity: multiple units supplied
• Recommended mounting: rotary tools and die grinders with compatible collet

How to use

Mount the flap cylinder securely in the collet or chuck of a properly rated rotary tool or die grinder, ensuring the 6 mm shank is fully inserted and tightened. Operate the tool at the manufacturer’s recommended speed range for flap abrasives and the material being worked; start with a moderate speed and increase if necessary while monitoring heat and surface condition. Apply light to moderate pressure, allowing the abrasive flaps to do the cutting; avoid forcing the tool to prevent excessive wear or heat buildup. Use steady, controlled passes across the workpiece to achieve an even result.

Usage recommendations

Use appropriate personal protective equipment including eye and respiratory protection and cut-resistant gloves. For ferrous metals, minimize dwell time in one spot to reduce heat and avoid altering temper. Replace worn flap cylinders when performance declines or when flaps are unevenly worn. Store dry and free from contamination to preserve abrasive performance.
