BOSCH HS2164 20 in 3 in Chisel - Heavy-Duty Concrete Demolition

In this review of the BOSCH HS2164 chisel, the bottom line is straightforward: this tool is for contractors and serious DIYers who need a durable, wide demolition chisel that cleans concrete and cuts troughs efficiently. The reviewer found the 3 in cutting head and the twin 60-degree angles deliver aggressive, predictable removal of concrete scale and rust, while the 20 in overall length gives leverage and reach. Our review highlights that the proprietary heat-treat process and 1-1/8 in hex shank make the chisel a reliable choice for rotary hammer rigs used on medium to heavy demolition tasks.

Key Features

• 3 in wide chisel: The broad cutting face removes concrete and scale faster than narrow points, reducing pass count on flat surfaces.
• Two 60-degree cutting angles: Those matched angles help the tool slice through concrete, rust, and scale cleanly for controlled material removal.
• 1-1/8 in hex hammer steel: The robust hex shank provides positive engagement with demolition hammers for stable, torque-resistant operation.
• Proprietary heat-treat process: Heat treatment improves durability and edge retention under repetitive impact conditions common in masonry work.
• 20 in overall length: Extra reach gives better leverage for prying and allows the operator to work from a safer distance on larger jobs.

Who It's For

The BOSCH HS2164 is aimed at professionals and experienced home renovators who use rotary hammer demolition tools frequently and need a chisel that lasts through repeated impact work. It suits concrete repair, surface prep before overlays, cutting troughs for conduit, and removing rusted or scaled material from slabs.

Those who should look elsewhere include casual users who only need occasional light chiseling or very precise sculpting tools; the wide 3 in blade and heavy-duty design are overkill for delicate or very small-scale tasks.

Pros & Cons

Pros

• Wide 3 in blade speeds flat-surface removal and reduces time on concrete cleanup.
• Two 60-degree cutting angles give cleaner, more controlled cutting through concrete, scale, and some asphalt.
• Durable 1-1/8 in hex construction and Bosch heat-treating improves longevity under repetitive use.
• 20 in length provides added reach and leverage for demolition tasks.

Cons

• Heavy-duty profile and wide blade make it unsuitable for fine-detail work or tight corners.
• Not designed for precision cutting; users needing narrow grooves should choose a pointed or narrower chisel.

Frequently Asked Questions

Will this chisel fit my rotary demolition hammer?
The HS2164 uses a 1-1/8 in hex shank, so it fits tools that accept that hex size or compatible adapters.

Is this chisel suitable for asphalt?
It can cut some asphalt, but it is optimized for concrete, scale, and rust removal rather than extensive asphalt work.

How does the heat treatment affect durability?
The proprietary heat-treat process increases edge retention and resistance to impact wear, extending service life under heavy use.
