PRODUCT FAQ

  1. What is 3M's Standard Abrasives™ HS Mini-Brush 875700 used for?

    The Standard Abrasives HS Mini-Brush 875700 is a versatile abrasive tool designed to blend, finish and deburr edges, contours and flat surfaces on metals.

  2. Is the 4-1/2 in x 4 in x 5/8-11 FB018 size suitable for my needs?

    Yes, this size of mini-brush make it ideal for cleaning tight areas such as slots or grooves. It fits easily into most angle grinders that run at maximum speeds up to approximately 13,000 RPM.

  3. How long does the brush last?

    The life of an abrasive tool depends on many factors like speed, pressure and frequency of use. However this particular model is engineered using high-performance ceramic grain which offers excellent durability and strength - so you can expect long-lasting performance from your investment.

  4. Can I reuse a brush after washing it with water?

    We do not recommend washing abrasive tools like theHS Mini Brush with water as it may cause damage to existing coating or fine grit particles left inside its structure due to chemical reactions,dulling their effectiveness. Also excess exposure to moisture could accelerate rusting especially metal brushes.Experience shows secondary use would only give suboptimal results comparedto new ones.

Restore Original Finishes

Conventional methods for blending weld traces and other imperfections can be time consuming and unpredictable. The Standard Abrasives™ High Strength Mini-Brush restores the original appearance of metal parts quickly and easily. Users begin by welding and setting the grain as normal. Then, the Standard Abrasives™ High Strength Mini-Brush follows to deliver stainless finishes.

The brush is constructed by attaching thin flaps of nonwoven abrasive material mounted to a fiberglass core. Its design utilizes the "face" of the material rather than the "edge," resulting in fine finishes without leaving the traces of lines associated with the ganged arbor hole discs. The flaps are buoyant and responsive, so, rotating on the workpiece they splay out subtly and cover more surface area to eliminate gaps. The brush easily attaches to a die grinder or rotary tool and can be brought to the workpiece if necessary. It is made with high strength (HS) buff and blend material, which has greater tear resistance and is perfect for use on final finishing of irregular shaped parts.

Benefits of Open Web Abrasives

Standard Abrasives™ High Strength Mini-Brush mixes aluminum oxide mineral and nonwoven nylon fibers with a resin bond, resulting in a dense open web. Resin bonds tolerate heat and help enhance overall durability of the abrasive. Aluminum oxide mineral cuts sharp and is friable, fragmenting under heat and pressure to reveal sharp cutting edges, achieving a consistent cut throughout the life of the abrasive.

Gaps between the nonwoven nylon fibers allow swarf and debris to escape, so the abrasive does not get clogged with buildup and keeps cutting sharper for longer. Moreover, the nylon fibers are buoyant and responsive, so users can achieve a consistent cut without gouging or marring the workpiece. Given that maintaining part geometry – especially on fabricated steel parts – is often a top concern, the mini-brush's ability to conform to the substrate without compromising part geometry is one of its key benefits. It helps reduce the likelihood of having to discard scrap parts due to incorrect tolerances, as well as minimize the need for rework.

Variations of the High Strength Mini-Brush

The Standard Abrasives™ High Strength Mini-Brush is color coded by grade to help users quickly identify the right grade for their application. Grades include medium (MED) and coarse (CRS). Medium grades will cut less aggressively but leave a finer scratch pattern, whereas coarse grades will cut more aggressively and leave a rougher scratch pattern.

Altogether, the High Strength Mini-Brushes are quality abrasives, providing users with a fast and easy way to restore workpiece finishes to their original condition.
