Chicago Pneumatic Clay Diggers: High Power-to-Weight Performance for Tunneling & Trenching

When excavation projects require cutting through dense clay, profiling tight trenches, driving subterranean tunnels, or executing precision light demolition, standard paving breakers are simply too heavy and clumsy. The Chicago Pneumatic Pneumatic Clay Digger Series—anchored by the CP 0111 and the legendary CP 0222—is the industry benchmark for high-performance digging and lateral earthworks.

Engineered with a superior power-to-weight ratio, these tools pack the punch of a light concrete breaker into a slim, easy-to-guide chassis. Known as “trench diggers” or “pick hammers” across the globe, this lineup maximizes operator throughput when slicing through high-cohesion soils, shale, and heavy masonry without sacrificing control on vertical or overhead planes.

Built for Unyielding Substrates: Core Features

Both models in the Chicago Pneumatic clay digger family are forged to outlast harsh, wet underground environments with minimal toolroom maintenance:

• Heat-Treated Alloy Steel Components: Every high-stress component, from the backhead to the cylinder, is forged from high-grade steel and precision heat-treated to resist stress fractures and extreme abrasive site wear.
• Trouble-Free Latch Retainer: Designed for high-speed tool transitions. The heavy-duty mechanical latch securely pins clay spades, moil points, and chisels into place with a swift manual flip.
• Flexible Trigger Layouts: Offered in inside trigger (CHIT) configurations to protect operator fingers from falling rock or debris, as well as outside trigger versions for maximum downward leveraging power when wearing heavy safety gloves.
• Long Service Intervals: Stripped of unnecessary internal complexity, these valved percussive mechanisms require minimal servicing to sustain peak operating efficiency over extended production shifts.

Model Breakdown: Match the Weight to Your Work

1. CP 0111: The Heavy-Duty Trench Master (30 lb. Class)

Operating firmly in the 30 lb. weight class, the CP 0111 is the heavy hitter of the digging lineup. Featuring an extended 3.5-inch cylinder stroke, this model delivers a slower, deeper-penetrating blow explicitly optimized for breaking up tough, deeply compacted materials, calcified soils, and mass masonry bulkheads.

• Best For: Deep utility trenching, excavation shafts, building foundation cut-ins, and light concrete slab demolition.
• Air Inlet: 3/8″ NPT

2. CP 0222: The Agile Global Best-Seller (22 lb. Class)

The CP 0222 is Chicago Pneumatic’s global best-selling digger for rental yards and municipal fleets worldwide. Weighing a nimble 22 lbs, its ultra-slim, compact profile allows an operator to navigate horizontal and overhead orientations with minimal back strain. Despite its light footprint, it processes a matching volume of airflow to generate aggressive percussive frequencies.

• Best For: Subterranean tunneling, lateral utility work, overhead scaling, and light demolition inside confined spaces.
• Air Inlet: 1/2″ NPT

Technical Specifications Matrix

Primary Applications

Spade Compatibility: The CP clay digger series pairs flawlessly with a broad menu of 7/8” and 1” hex-shank accessory steels, including traditional wide clay spades, narrow chisels, flat asphalt cutters, and standard moil points.

• Clay & Soil Excavation: Cutting through dense clay, hard-packed earth, muck, silt layers, and embedded shale formations.
• Tunneling & Caisson Work: Lateral drifting and overhead scaling inside subterranean mining tunnels, sewer trunks, and civil caissons.
• Trenching & Utilities: Slicing clean trench walls for gas line tie-ins, water pipes, electrical conduits, and fiber optic networks.
• Light-Duty Demolition: Stripping architectural masonry, knocking out old brick walls, and breaching low-PSI floor overlays or protective plaster coatings.

The Chicago Pneumatic CP 0111 and CP 0222 series deliver the exact degrees of physical balance, durability, and raw hitting speed required to conquer stubborn ground. Choose the robust 30-lb trench master or the lightweight, globally trusted 22-lb workhorse to keep your field crew safe, fast, and highly productive on the job site.
