Some examples of what we can do
Supplementary procedures
We do everything in-house
State-of-the-art machinery allows us to manufacture hard metal parts in any required shape and with the desired surface quality. Whether the tolerances are in the tenths, hundredths or even thousandths range, we always find the ideal machining process. And everything takes place under one roof.
Benefits shown using grinding mandrels
For you, using solid hard metal mandrels means lower unit costs and higher quality.
Or: you earn more money even though they cost more than steel mandrels.
The company
Toolmakers and (poly)mechanics produce sophisticated special tools, precision machine parts for extreme loads and hard metal parts in the micro range for all applications. The company, which was founded in 1969 and has its headquarters in Gränichen, also owns the Rotodur SA subsidiary in Biel.
About hard metal
Hard metal is a composite material that is usually magnetic. It is harder than pure metals, alloys and hardened steel. This extends the service life of your tools and increases profitability.
