Flap Mounted Grinding Wheel LUKAS NK 24 N BA Soft 40×20×6 for shaft-mounted polishing

The LUKAS NK 24 N BA Soft flap-mounted grinding wheel 40×20×6 is a shaft-mounted abrasive accessory engineered for fine finishing, deburring and surface preparation. With a flexible flap construction and soft backing, this wheel adapts to contours and provides consistent contact on uneven surfaces. It is suitable for use in handheld and bench-mounted rotary tools that accept a 6 mm bore and is intended for work on metal and a variety of other materials where a gentler abrasive action is required.

Advantages

This flap-mounted grinding wheel combines a soft backing with layered abrasive flaps to deliver uniform material removal and reduced risk of gouging. Its compact 40 mm outer diameter and 6 mm shaft fit make it compatible with many shaft-mounted polishers and rotary tools, while the construction supports heat dissipation during light to medium polishing tasks. The soft grade improves surface finish quality and reduces the likelihood of creating sharp edges or excessive stock removal.

Suitable for

• Fine finishing and polishing of metal surfaces
• Deburring of small parts and edges
• Surface preparation before painting or coating
• Light rust and scale removal
• Working on contours and irregular shapes

Key specifications

• Outer diameter: 40 mm
• Inner bore (shaft): 6 mm
• Thickness: 20 mm
• Abrasive type: flap-mounted construction with soft backing
• Intended use: shaft-mounted grinding and polishing
• Compatibility: handheld and bench rotary tools with 6 mm arbor

How to use

Mount the flap wheel onto a rotary tool with a compatible 6 mm shaft and ensure it is securely fixed before operation. Start at low speed to verify balance and apply light, even pressure while moving across the workpiece. Use steady, overlapping passes for uniform finish and avoid prolonged dwell in one spot to prevent overheating or excessive material removal. Observe the tool manufacturer's recommended speed limits and wear appropriate personal protective equipment.

Usage recommendations

For best results, select this soft flap wheel when a smooth surface finish is required rather than aggressive stock removal. Monitor wheel wear and replace when flaps are significantly eroded to maintain consistent performance. When working on small or delicate parts, reduce tool speed and use light pressure to preserve detail and avoid deformation.
