1. On a tour of Czechoslovak machine plants, ceramic cutting tools were seen
being used in two locations; one place was TOS Kurim and the other was the
Research Institute for Machine Tools and Cutting Work (Vyzkumny ustav obra-
becich stroju a obrabeni), at Na Zertvach 24, Prague VIII.

changeable hard metal cutter which is manufactured by various Western firms the inter-
The cutter holder is manufactured in just about the same way as the Western
ones are,
3. The advantage of using this cutter is that the tool does not have to be refaced.
The ceramic cutter, it has been estimated, will be so inexpensive to manufacture
that when one of them wears out it will be better to replace it with a new one
rather than use hard-metal cutters which must be refaced (reground). When
working in steel, it is said that the same cutting speed is reached as when
using hard-metal cutters under the same conditions. When working with cast iron,
the speed is said to be double that obtained by working it with hard-metal
cutting tools. The life of the cutting edge when working on cast iron may be
estimated to be about one hour. A ceramic cutting tool with a square section
should thus be usable for eight hours, in view of the fact that one could
turn the cutting edge, i.e., change it,
