Grinding flap wheel KLINGSPOR KM 613 40×20×6 mm grit 100 for rotary tools

The KLINGSPOR KM 613 flap grinding wheel, 40×20×6 mm with grit 100, is a compact abrasive accessory engineered for use with rotary tools and die grinders. Its arranged abrasive flaps provide uniform material removal and controlled surface finishing on metal, wood, plastics and composite materials. The wheel's small diameter and central bore are intended for high-speed rotary applications where precision deburring, edge rounding and fine surface conditioning are required.

Advantages

The flap construction maintains a consistent cutting profile as the abrasive wears, enabling even stock removal and predictable finish quality. Grit 100 offers a balance between cutting speed and surface smoothness, producing fine-to-medium satin finishes without aggressive gouging. The compact 40×20×6 mm size improves access to confined areas and supports precise work on small parts. Designed for rotary tools, the wheel runs at high speeds while providing stable operation and reliable service life when used within the tool’s recommended RPM range.

Suitable for

• Deburring and removing flash from metal and plastic parts
• Edge rounding and softening sharp corners on machined components
• Blending welds and smoothing joints on sheet metal
• Fine surface conditioning and preparation before painting or coating
• Light finishing on wood, plastics and composite materials

Key specifications

• Overall diameter: 40 mm
• Working width: 20 mm
• Bore diameter: 6 mm (center hole for rotary tool mandrel)
• Abrasive grit: 100 (medium–fine)
• Abrasive type: flap-style cloth/sanding composite designed for consistent wear
• Intended mounting: rotary tools and die grinders with matching shank/adapter

How to use

Install the flap wheel on a compatible rotary tool or die grinder using an appropriate mandrel or adapter that matches the 6 mm bore. Secure the wheel according to the tool manufacturer’s instructions and confirm the maximum safe RPM of both the wheel and the tool. Run the tool at moderate speed and apply light, even pressure to the workpiece, moving the wheel across the surface to avoid concentrated heat buildup. For best results, use steady passes and allow the abrasive flaps to wear uniformly; avoid forcing the wheel into the workpiece to prevent premature wear or glazing.

Usage recommendations

Wear appropriate personal protective equipment including eye and respiratory protection and gloves. Use the wheel within the tool’s rated speed limits and ensure the workpiece is secured. For different materials, test on a scrap piece to verify the finish and adjust feed pressure or speed as needed. Replace the wheel when abrasive performance declines or damage is observed.
