APPLICATION
Parking Garage & Structural Deck Repair
The KTC-3S and 4S deliver up to 2,200 BPM of impact force to chip away spalled concrete, patch damaged ramps, and expose rusted rebar on parking structures. The protected inside-trigger D-handle gives operators a firm, comfortable grip when chipping floor slabs and overhead bridge decks.
Building Restoration & Masonry Rehabilitation
Engineered for commercial restoration, these air-powered chipping hammers quickly remove deteriorated mortar joints, crumbling stone, and damaged exterior stucco. The rugged 4-bolt handle design withstands heavy continuous vibration while maintaining precise chisel control along historic building facades.
Light Concrete Demolition & Wall Teardowns
These pneumatic hammers easily break down concrete block walls, interior brick partitions, and excess slab pours during selective demolition jobs. The secure screw-on ball retainer keeps chisel bits locked tightly in place to prevent accidental tool ejection during intense chipping.
Industrial Tank, Formwork & Surface Cleaning
Designed for plant and jobsite cleanup, this tool chips away dried concrete splatter from formwork, thick boiler scale, and hardened chemical deposits inside mixing tanks. Crews can select the rapid 3-inch stroke for lighter surface scarification or the 4-inch stroke for deeper industrial removal.
FREQUENTLY ASKED QUESTIONS (FAQ)
What is the difference between the KTC-3S and KTC-4S chipping hammers?
The KTC-3S features a 3-inch stroke delivering 2,200 BPM at 19 lbs for fast chipping and surface cleanup. The KTC-4S features a longer 4-inch stroke delivering 2,000 BPM at 20 lbs for heavier concrete demolition.
What air compressor requirements do these tools have?
The KTC-3S requires at least 31.5 CFM and the KTC-4S requires at least 33.23 CFM at standard 90 PSI operating pressure using a 3/8-inch NPT air line.
What chuck size and retainer style do these chipping hammers use?
Both models accept 0.580-inch Hex and 0.680-inch Round shank chisels, secured by a heavy-duty screw-on ball retainer for safe, reliable bit retention.
What are the advantages of the 4-bolt D-handle with inside trigger?
The 4-bolt back head construction provides superior structural durability under heavy impact, while the inside trigger protects the throttle mechanism from accidental engagement and jobsite damage.
