Micro burrs type WRC and type RBF are
optimally suitable for both manual and
automatic machining tasks. They stand out
thanks to the combination of good stock
removal and high-quality finish. Almost all
materials up to a hardness of 60 HRC can be
machined. If higher stock removal is required,
micro burrs can be used as support in areas
where mounted points are usually used.
They work with little vibration.
