Blast Through Reinforced Concrete and Tough Masonry with Self-Sharpening Power

Experience a dramatic increase in jobsite efficiency with the Bosch HS2166 20-1/2-Inch Superkut Chisel. Specifically designed for high-impact 1-1/8-inch hex electric breaker hammers and heavy-duty pneumatic jack hammers, this premium demolition attachment features a unique 2-3/4-inch wide profile that is meticulously engineered to maintain a self-sharpening geometry during intense structural fracturing. By directing concentrated impact forces across its specialized cutting edge, the Superkut chisel easily busts through massive concrete slabs, reinforced structural pillars, stone wall configurations, and thick foundations. It provides commercial demolition contractors and civil engineers with an incredibly fast-penetrating solution that stays sharp up to 2X longer than standard chisels.

Built to meet the punishing demands of modern job sites, the Bosch HS2166 is forged from premium-grade alloy steel and treated with a proprietary, advanced thermal hardening process that optimizes impact resistance and limits metal fatigue. Its substantial 20-1/2-inch overall length delivers an extended operational reach, helping operators maintain a healthy, upright posture that drastically minimizes physical fatigue and back strain during long downward demolition shifts. The precision-machined 1.125-inch (1-1/8") hex shank guarantees a flawless universal brand fit, locking firmly into all standard heavy breaker hammers. This Italian-made masterpiece resists splitting and cracking under rapid, extreme vibration, minimizing tool swap downtime and keeping high-volume industrial jobs moving smoothly ahead of schedule.

Key Features

  • Premium Superkut Profile: Specialized geometric configuration accelerates concrete penetration speeds while actively maintaining its shape under heavy daily wear.
  • Self-Sharpening Edge Technology: Retains its optimized cutting and wedging capabilities far longer, requiring fewer maintenance or resharpening breaks.
  • Extended 20-1/2 Inch Reach: Generous length keeps the operator upright during floor-level demolition, significantly reducing lower back fatigue.
  • Proprietary Heat-Treat Forging: Premium industrial alloy steel formulation engineered to combat structural fatigue and eliminate catastrophic bit breaks under load.
  • Universal 1-1/8 Inch Hex Shank: Forged to precise tolerances for total cross-compatibility with standard pneumatic and electric heavy demolition tools.

  • (1) Bosch HS2166 1-1/8" Hex Shank 2-3/4" Superkut Demolition Chisel Bit

PRO-TIP: To unlock the full self-sharpening action of the Superkut profile, ensure you change the angle of attack slightly every few strokes rather than keeping the hammer perfectly vertical. Alternating your tool lean between 75 and 90 degrees induces a natural shearing stress on the underlying aggregate, triggering faster concrete spalling while keeping the cutting tip evenly worn and raked for the next impact run!

Outstand Product!! 😉
Color: 14AWG-1 Lead
This is my second (at least) Nilight wiring harness. I wanted to re-do the lights on my Rhino 660. This makes it SO EASY! 👍🏼😉 And a hell-of-a-deal!! All I had to get was a "reamer" drill bit to enlarge the switch holes on my dash. Run the wire, attach the ends to the light, switch & power source, all done. I did add "shrink tubing" to my connections to add an extra layer of insulation/weatherproofing. 👍🏼

Definitely a good buy very professional craftsmanship
Color: 14AWG-1 Lead
As a retired master technician for Honda and all makes and models of automobiles this harness is a cut above the others is put together immaculately and anyone that can put a wire through the firewall I purchased my light bar to harbor freight 22 in great lighting but their harness kit was 56 bucks I paid under 24 this and it looked identical except the switch on this is actually much more appealing cosmetically and works well functionally just had to drill a hole in one of the blanks 4 switches in my truck made it fit perfect and has worked flawlessly since I put it in a couple weeks agodefinitely do your homework sometimes I find great deals at harbor freight that nobody can touch on Amazon but then other times vice versa Amazon has a great product at a great price compared to harbor freight in other retailers

Perfect for roof LED light bar
Color: 14AWG-1 Lead
This worked great for wiring a 50" LED light bar to the roof of my SUV. This kit conveniently includes a relay, switch with backlight, and fuses. I used a step bit to drill the pilot hole for the switch and worked my way up until it was the right size. I zip tied the excess wire and it made for a clean install. My only complaint is that the ring terminals were too large for the battery but it was easy to crimp smaller ones on.

Good harness
Color: 14AWG-1 Lead, Color: 14AWG-1 Lead
I bought this for the nilight 12in bar. It came in the same box and right on time. It easily connected to the light bar and into the engine. There is a lot of slack between the battery terminals and the bar, but it’s understandable if maybe you wanted to mount this on the back of your vehicle. I wish there was more slack between the relay and the switch, as having to go from the battery through the firewall and into the cabin requires sufficient length. I ended up getting rid of the circular switch that came with it and it’s complimentary connectors to replace it with my own rectangular rocket switch that fit better in the cabin. Overall good product. I’d advise to wrap electrical tape around the quick disconnect to prevent any weather wear.
