Harjaharja 3M radiaalinen K120 75x9mm BB-ZS tyyppi C

Bristle Brush 3M Radiale K120 75x9mm BB-ZS Type C is a replacement brush head intended for surface finishing and light deburring of small workpieces and detailed areas. The brush uses a K120 abrasive grade in a compact 75 x 9 mm configuration and fits tools that accept BB-ZS Type C mounting. It is designed to remove rust, paint residues and oxidation while producing a consistent surface texture suitable for preparation before painting or final finishing.

Advantages

The bristle construction with K120 abrasive provides controlled material removal without aggressive cutting, allowing even working on thin or delicate parts. Its compact diameter and narrow face enable access to confined spaces and detailed contours. The BB-ZS Type C mounting ensures a secure fit on compatible tools and consistent rotational balance for steady performance. The brush offers uniform surface conditioning, reducing the risk of gouging while delivering repeatable finish quality.

How to use

Install the brush head on a tool that accepts BB-ZS Type C mounting, ensuring the connection is secure and the tool is powered off during fitting. Operate the tool at the manufacturer’s recommended speed for abrasive bristle brushes to avoid overheating or premature wear. Apply light to moderate pressure and use steady, controlled passes across the work surface to achieve even material removal and consistent texture. Inspect frequently to avoid excessive stock removal on thin sections.

Recommendations

Select the K120 grade bristle brush when a medium-fine finish is required; for heavier material removal choose a coarser grade and for finer finishing select a finer grade if available. Wear appropriate personal protective equipment including eye and respiratory protection, and follow the power tool manufacturer’s safety instructions. Store the brush in a dry area away from solvents and extreme temperatures to preserve bristle and abrasive performance.
