APPLICATION
Concrete Surface Repair & Demolition
The KTC-T3S and T4S deliver up to 2,200 BPM of rapid impact energy to chip spalled concrete, expose rusted rebar, and trim excess concrete pours. The ergonomic top-trigger handle gives operators responsive throttle control when feathering edges and leveling uneven floor slabs.
Metal Fabrication, Foundry & Weld Cleaning
These air-powered chipping hammers quickly remove thick weld slag, clean metal castings, and strip stubborn foundry scale in fabrication shops. The heavy-duty screw-on ball retainer holds chisels locked tightly during continuous, high-impact metal dressing.
Bridge Deck & Structural Rehabilitation
Engineered for civil restoration, these tools efficiently remove deteriorated concrete from bridge decks, support pillars, and parking structures. The included whip hose reduces air line strain, giving workers better reach and agility on scaffolding and overhead repairs.
Industrial Tank, Boiler & Pipe Scaling
Designed for plant maintenance crews, this chipping hammer chips away hardened chemical deposits, boiler scale, and dried cement inside mixer drums. Contractors can choose between the fast 3-inch stroke for light scaling or the hard-hitting 4-inch stroke for heavy industrial buildup.
FREQUENTLY ASKED QUESTIONS (FAQ)
What is the difference between the KTC-T3S and KTC-T4S chipping hammers?
The KTC-T3S features a 3-inch stroke delivering 2,200 BPM at 19 lbs for fast chipping and weld dressing. The KTC-T4S has a longer 4-inch stroke delivering 1,800 BPM at 20 lbs for heavier concrete demolition.
What size air compressor is required to operate these tools?
The KTC-T3S requires at least 31.5 CFM and the KTC-T4S requires at least 33.2 CFM at standard 90 PSI operating pressure via a 3/8-inch NPT air connection.
What chuck size and retainer mechanism do these models use?
Both models accept industry-standard 0.580-inch Hex and 0.680-inch Round shank chisels, secured by a durable screw-on ball retainer that prevents bit ejection.
Why is the top-trigger design and included whip hose beneficial?
The top trigger gives operators instant variable throttle control in awkward positions, while the included flexible whip hose prevents hose kinks and reduces wrist fatigue on the job.
