3M ručný blok 7100247093 ručný brúsny blok, plast, 115×80 mm

The 3M Handblock 7100247093 hand sanding block is a compact plastic-backed tool sized 115×80 mm designed to secure abrasive sheets for manual sanding operations. It offers a flat, rigid surface that distributes pressure evenly across the abrasive, enabling consistent contact with the workpiece when smoothing wood, filler, paint and performing light metal finishing. Its lightweight construction and ergonomic shape support controlled movements during detail sanding and broader surface preparation tasks.

Advantages

This hand sanding block provides a stable backing for abrasive sheets, improving flatness and control compared with sanding by hand alone. The plastic body resists absorption of moisture and filler residues, maintaining consistent performance in workshop conditions. Its compact dimensions make it suitable for accessing confined areas and holding standard-sized sanding sheets securely for both fine and medium sanding grit ranges.

How to use

Attach an appropriately sized abrasive sheet to the block, ensuring the abrasive is held firmly and the edges are aligned with the block profile. Hold the block with a comfortable grip and apply even, moderate pressure while moving across the surface in the desired direction, using long strokes for flat areas and shorter, controlled motions for contours. Replace abrasive sheets when the grit becomes clogged or worn to maintain effective cutting performance.

Recommendations

Use the hand sanding block with compatible grit ranges depending on the task: coarser grits for material removal and shaping, medium grits for smoothing, and fine grits for finishing. Keep the block and abrasives clean of debris to prolong working life and achieve consistent results. For curved or highly contoured surfaces consider using a flexible backing or hand-held sanding methods to better follow the profile.
