Thrillers for the production of internal threads.

With these tools, three different machining processes can be combined into one single work process.

Without any necessity for a tool change, the thrillers drill the thread hole, countersink the hole and cut the thread all at the same time.

The 4-fluted thrillers are characterised by their excellent stability and their low-vibration operation.

By doubling the number of cutting edges we have reduced machining times and increased tool life.

Main application range:

• Short-chipping cast materials

Advantages:

• Faster milling
• Longer tool life
