The Husqvarna 576633503 Wide Chisel is a genuine OEM replacement designed for the SB152 demolition equipment. As a factory-original component, this chisel is manufactured to Husqvarna's exact specifications, ensuring the correct geometry, steel grade, and shank dimensions for a secure, properly seated fit in the SB152 breaker. DHS Equipment supplies this part to help keep your demolition equipment operating at full capacity.
Key Features
- OEM-Grade Tool Steel — manufactured from hardened alloy steel to the same material specification as the original, delivering the impact resistance and wear life a demolition chisel demands under continuous breaking loads.
- Correct Shank Fit — machined to the exact shank profile and retaining-pin dimensions of the SB152 breaker, so the chisel seats fully and locks without reworking or shimming.
- SB152 Compatibility — verified fitment for the SB152 demolition breaker attachment, cross-reference part number 576633503 against your parts diagram before ordering.
- Wide Profile Breaking Power — the broad tip distributes impact force across a larger surface area, making this chisel well suited to slab demolition, trench breaking, and surface scarifying where a narrow point would skate or embed too deeply.
- Operational Safety — using the correct OEM chisel ensures the retaining hardware engages as designed, preventing tool ejection during high-frequency impact cycles.
A breaker chisel is the direct contact point between the hydraulic hammer and the material being demolished. Each blow transfers thousands of pounds of impact force through the chisel tip into concrete, asphalt, or rock, so the steel must withstand repeated shock loading without cracking or deforming at the shank. A chisel that is worn, the wrong profile, or incorrectly seated can reduce breaking efficiency, accelerate wear on the breaker's internal retainer, and create a risk of the tool backing out under load. Replacing a worn chisel with the correct OEM part restores full impact transfer and keeps the SB152 breaker performing as intended.
