Dynex 0,7 x 22 mm – Very robust, small separating and grinding disc especially for non-precious metal alloys and model casting alloys.

Function & Performance
Very robust, glass fiber reinforced separating and grinding disc, especially made for separating, cutting and grinding non-precious metal and model casting alloys.


  • Ideal for separating and grinding small areas such as shape correction.
  • Very robust, even when under extreme strain such as lateral pressure and high rpm.
  • Very compact size for precise processing


Dynex separating discs from Renfert are highly precise tools, of which we are very proud. 40 years of experience and permanent, intensive development work are incorporated in the discs. They are produced using the latest manufacturing methods and the strict raw material controls ensure that only the materials are used.

Our separating discs attain a cutting speed of up to 300 km/h (186,4 miles per h). They separate powerfully, safely and highly precisely at high speed. To achieve this type of high performance, a careful combination of selected raw materials and a high degree of dimensional accuracy is decisive. In addition to the very high-quality abrasives, such as the finely coordinated diamond particle sizes, as well as aluminum oxide with a very high degree of purity, the binding agents are also consistently tailored to their respective area of application.

All Dynex separating and trimming discs, including the ultra-thin versions, are reinforced with double glass-fiber. The reinforcement is a component of the disc core and is fused completely with the carrier material. In a nutshell this means for you: outstanding durability, flexibility and reliability.
