Product Overview

The ZPT-CP or ZOIC Chicago is our modified version of the CP-9361; which has been the workhorse of the fossil preparation world for donkeys years due to its versatility, power and durability. We have modified it specifically for fossil preparation. Each tool comes with its serial number from Chicago Pneumatic, confirming the authenticity of the parts.

  • 2.5mm high grade tungsten carbide stylus
  • Low air consumption
  • Hardened and tempered bushing for fossil prepration
  • Rubber coated for thermal insulation and vibratory dampening
  • Fitted with a silencer
  • Authentic CP-9361 Parts

The Chicago Pneumatic (CP-9361) is the workhorse of many established workshops, universities and museums. This tool is modified specifically for fossil preparation by ZOIC PalaeoTech, with a hardened bushing and 2.5mm tungsten carbide stylus. The ZOIC Chicago is an excellent all rounder.

Variants of the CP-9361 have long been used on hard matrices due to their impact-driven internal mechanism, and are found in just about every professional prep lab in the world. The impact-driven internal mechanisms (piston/cylinder combination - more details here) give the tool power, whilst the size allows for detailed work. 

We have created a new stylus bushing, which has been hardened and tempered. This prevents wear from the 2.5mm tungsten carbide stylus as it travels backwards and forwards, thus preventing ‘wobble’ in the point. We have also given the tool a rubber coating to minimise vibrations, provide more grip and provide some kind of insulation against the cold air flowing through (a nice touch considering so much fossil preparation takes place in unheated garden sheds!). Following consumer feedback, we have even fitted our version with a silencer to reduce noise output.

The actual air consumption is about as low as it gets for a fossil preparation tool at only 6lpm (0.2cfm), providing 13,500 bpm. The ZOIC Chicago has a nominal and maximum operating pressure of 6 Bars (90 PSI).

We modify each tool right here in Dorset, and take enormous pride in our workmanship. Each tool is quality controlled before it leaves our workshop. We use the geniune article as our starting point, sourced from Chicago Pneumatic, which means that the cylinder and piston are hardened and durable. We design all of our modifications to last the trials of fossil preparation.

If you are a beginner to fossil preparation, and your budget will stretch to just one air pen, we recommend this tool for the majority of British rocks due to its power/delicacy balance. The ZOIC Velociraptor is another contender if you are doing more delicate and fiddly work on more fragile fossils. The ZOIC Chicago also comes as part of a Starter Kit with a 24l Air Compressor, Ear Defenders, Safety Glasses and a dust mask.
