jack hammer chisel

Kits commonly include flat (wide) and pointed chisels plus digging and scraping variants — for example clay spades, flat spades, and larger scraping chisels for heavier material removal.

Listings show a 1 1/8" hex shank for demolition shovel–style chisels and a .401 shank for air-hammer–style tools.

Most chisels are described as heat-treated alloy steel; one demolition shovel is specified as heavy-duty 40Cr steel.

Electric demolition hammers typically use a high-strength alloy chuck with quick clamping/assembly, while some air hammers use a ball-lock quick-change chisel retainer.

They’re used for demolition, trenching, chipping, and breaking holes in concrete, block, brick, and tile. Shovel-style chisels are also used for digging through packed soil, clay, and similar materials.

Kits commonly include a carrying case plus tools and maintenance or safety items such as wrenches/hex keys, oil bottles, grease, gloves, goggles, carbon brushes, and masks.

Listed impact rates vary widely — roughly from about 1,350 BPM on some electric breakers up to around 3,000 BPM for certain air-hammer kits.

Shovel-like, triangle-blade, and clay-spade chisels are described for digging through packed soil, clay, and similar garden-style tasks.
