This round Busch carbide bur is a power cutter for gold alloys.
FIG 1AU POWERCUT CARBIDE BUR
Holes drilled with the twist drill 4205S are enlarged as required with larger round carbide burs 1AU. This creates a secure mount for the rondiste of the gem to be set. Cutting in difficult to reach corner areas and also a fine refinishing can be done with the small diameter of 0.4 mm.State-of-the-art manufacturing techniques give these round burs a powerful blade geometry of the kind normally only found on steel tools.

The special material properties of the carbide metal guarantee a remarkably long service life compared with the familiar round steel burs when producing jewellery made on gold. In addition to this, the new round bur permits cost-efficient working on widely used jewellery materials as platinum, titanium and even steel.
