2.5 mm diameter stone-grade tungsten carbide straight chisel stylus for fossil preparation, to fit the ZOIC Chicago (Extended Reach). This stylus is >1.5cm longer than the standard ZOIC Chicago. 

PRODUCT WARNING: This stylus is not suitable for use in the ZOIC Chicago. It is ONLY for use in the ZOIC Chicago (Extended Reach) Version. It will break if used in the standard ZOIC Chicago which does not have the elongate, hardened bushing to provide adequate support for the carbide.

Straight chisels are best suited to soft rocks. The edges can chip if used on hard rocks.


Can I use this stylus in the CP-9361?

No. This stylus will not fit in the Chicago Pneumatic CP-9361. If you would like to convert your existing CP-9361 into a ZOIC Chicago, optimised for fossil preparation, check out our modification kits. We also stock original and genuine CP-9361 styli that will fit that model.


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.
