Grinding Discs Proline 40x20mm with 6mm Shaft A120 abrasive discs for rotary tools

Grinding disc made of abrasive linen with radial corundum grains, designed for use on rotary tools. The disc has a 6 mm shaft and compact dimensions — 40 mm diameter and 20 mm height — providing stable mounting for precision surface finishing, deburring and light material removal on metal, wood, plastics and composite materials.

Advantages

The Proline grinding disc features corundum abrasive for consistent cutting and a linen backing that ensures flexibility and conformability to complex shapes. Standard 6 mm shaft enables quick mounting in many rotary tools and die grinders. Small diameter and medium grit A120 deliver controlled material removal and fine surface refinement in detailed work.

Suitable for

• Deburring small metal parts
• Smoothing and finishing wood details
• Polishing plastics and composites
• Cleaning and shaping complex or contoured surfaces

How to use

Secure the 6 mm shaft of the disc in the compatible rotary tool collet or chuck and tighten according to the tool manufacturer’s instructions. Run the tool at appropriate speed for the material and grit — start at lower speeds and increase if necessary while maintaining steady, light pressure. Move the disc across the workpiece with controlled strokes, avoiding excessive dwell in one spot to prevent overheating or over-removal of material.

Usage recommendations

Use personal protective equipment (safety glasses, gloves and dust mask) and ensure the disc is not damaged before use. Match the A120 grit to the desired finish; for coarser removal choose a lower-number grit, for finer polishing use higher-number grits. Do not apply excessive pressure and avoid speeds beyond the rotary tool’s recommended limits.
