2mm diameter tungsten carbide rounded chisel for the ZPT-TB The Trilobite with pusher-plate o-ring and chisel-compatible spring. Manufactured from stone-grade tungsten carbide.

This chisel will not rotate when in use, due to our locking mechanism. The custom spring acts to hold the chisel in place. 

The rounded chisel is the most useful all-rounder chisel. The rounded chisel works better on harder matrix. 

When you order this stylus, you get:

• 1 x rounded chisel stylus
• 1 x pusher plate o-ring
• 1 x chisel-compatible spring

Spare springs are available separately. 

What is tungsten carbide?

Stone-grade tungsten carbide is by far the best material for fossil preparation – it withstands the abrasive nature of rock and stays sharp far longer than other metals like steel which will quickly blunt and wear down to nothing. However, tungsten carbide can be brittle. A stylus can last many years without requiring replacement when looked after correctly.
