FEIN 63722048014 cepillo de prepulido, nylon, 125 mm, rosca M14, 4000 rpm

For professionals who demand a satin finish without the swirl marks left by conventional abrasives, the FEIN 63722048014 pre-polishing brush delivers controlled surface refinement. Its 125 mm nylon bristle disc removes light oxidation, tool marks, and fine burrs while preserving dimensional accuracy. The M14 threaded hub mounts directly onto FEIN satin finishers and other compatible rotary tools, eliminating the need for adapters. Rated for up to 4000 RPM, this brush balances aggressive material removal with a smooth, uniform result on stainless steel, aluminum, and non-ferrous metals.

Highlights

• Nylon bristles provide a consistent pre-polish without embedding abrasive particles in the workpiece.
• 125 mm working diameter covers large flat areas efficiently while allowing edge access.
• M14 threaded mount ensures secure, tool-free installation on FEIN satin finishers.
• Maximum speed of 4000 RPM suits high-speed surface conditioning tasks.
• Versatile for pre-polishing, cleaning, deburring, and matting/satin finishing.

In daily use

Mount the brush on a compatible FEIN satin finisher and set the speed according to the material. For stainless steel, begin at a lower RPM and increase as needed to avoid overheating. The nylon bristles flex slightly to follow contours, making the brush ideal for blending weld seams, removing heat tint, and preparing surfaces for final polishing. After use, clean the bristles with a stiff brush or compressed air to maintain performance. The brush is also suitable for light deburring and cleaning on non-ferrous metals.
