STS spiral coils are designed to provide an innovative and avant-garde feature- they are equipped with inverted fill material which delivers excellent descaling, polishing or elimination of corrosive coatings from the surface of wires and rods via a constantly conducted process.
The external diameter of the coils is just 20 mm which facilitates reaching a zero internal diameter. The brushes are available in a vast gamut of sizes and fill materials. They are therefore, perfectly suited for use in a wide array of applications. The excellent designing and ground-breaking engineering are evident from the minute details and structuring of the components of the brush.
The STS coil is efficiently constructed with the fill material inside, held in place with a locking wire and backing tape on top.
