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.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 in wide chisel:\u003c\/strong\u003e The broad cutting face removes concrete and scale faster than narrow points, reducing pass count on flat surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo 60-degree cutting angles:\u003c\/strong\u003e Those matched angles help the tool slice through concrete, rust, and scale cleanly for controlled material removal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-1\/8 in hex hammer steel:\u003c\/strong\u003e The robust hex shank provides positive engagement with demolition hammers for stable, torque-resistant operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProprietary heat-treat process:\u003c\/strong\u003e Heat treatment improves durability and edge retention under repetitive impact conditions common in masonry work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20 in overall length:\u003c\/strong\u003e Extra reach gives better leverage for prying and allows the operator to work from a safer distance on larger jobs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe 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.
