AZUNO 20" 1-3/16" Hex Shank Jack Hammer Chisel Set, Point & Flat

The AZUNO 20-Inch Jack Hammer Chisel Set provides a dedicated two-piece tooling solution for heavy-duty demolition hammers and concrete breakers. Designed to tackle hard materials such as concrete, brick, stone, asphalt, cement walls, and tile flooring, this set serves construction, remodeling, and roadwork needs by pairing two fundamental chisel profiles in a single package.

Compared to standard 16-inch bits, the 20-inch extended length gives you extra reach and improved leverage. This additional length helps reduce the need to constantly bend over while working on floors and makes it easier to reach into deep, tight spots. The set includes one pointed chisel for starting holes and initial fracture work, alongside one flat chisel meant for scaling surfaces, chipping concrete, and removing floor tiles.

Both chisels are manufactured from forged 42CrMo steel and feature a heat-treated construction. This metallurgy delivers wear resistance and strength to withstand repetitive high-impact forces during demanding masonry and demolition tasks.

The primary trade-off is chuck compatibility. These bits exclusively fit 1-3/16-inch (30 mm) hex systems. They will not fit 1-1/8-inch, 11/16-inch, 1-1/4-inch, or 3/4-inch hex tools, nor are they compatible with SDS Max or SDS Plus rotary hammers, so you must verify your tool shank before purchasing.

Verdict: This set is an excellent choice for contractors and DIYers with compatible 1-3/16-inch hex demolition hammers who need the extended reach of 20-inch steel bits for floor and masonry work.

• Shank Size: 1-3/16 inch (30 mm) Hex
• Total Length: 20 inches
• Material: Forged 42CrMo steel (heat-treated)
• Included Pieces: 1 point chisel, 1 flat chisel
• Suitable Materials: Concrete, brick, stone, asphalt, masonry, cement, tile

A great fit if you:

• Own an electric jack hammer or breaker with a 1-3/16-inch (30 mm) hex chuck.
• Need extra reach to reduce bending during floor demolition or deep trenching.
• Require both a point chisel for breaking and a flat chisel for tile or surface scaling.

Consider something else if you:

• Use tools with SDS Max, SDS Plus, or different hex sizes such as 1-1/8-inch or 3/4-inch.
• Only need specialized accessories like asphalt cutters or clay spades not included in this two-piece set.
