FAQs
What type of material is this chisel best for?
This pointed chisel is most effective for breaking up concrete, splitting masonry, and penetrating hard stone.
What size shank does this chisel have?
The chisel has a 19mm hex shank.
Can I use this chisel with any rotary hammer?
No, this chisel is specifically designed for demolition tools and breakers that accept a 19mm hex shank. It is not compatible with standard SDS or other chuck types unless they specifically accommodate a 19mm hex fitting.
How durable is the steel construction?
The chisel is constructed from toughened, heat-treated steel, designed to withstand the repeated heavy impacts of demanding demolition work and maintain performance over extended use.
What is the overall length of the chisel?
The chisel has a total length of 400mm.
How should I maintain the chisel for longevity?
Clean off debris after each use, inspect for damage, store in a dry place, and lightly oil the shank to prevent rust.
Is the pointed tip suitable for wide surface demolition?
The pointed tip is designed for concentrated impact and penetration. For wider surface breaking, a flat or spade chisel might be more efficient, though this pointed chisel can initiate breaks in larger areas.
Troubleshooting
Chisel not seating properly in the tool
Ensure the tool's chuck is fully open and that no debris is obstructing the shank or the chuck mechanism. Verify that the tool is designed for a 19mm hex shank.
Reduced breaking efficiency
Check if the chisel tip is damaged or excessively worn. Ensure you are using adequate force and that the demolition tool is functioning optimally. Clean any material buildup on the tip.
Chisel shank showing signs of wear or damage
Inspect the shank for any burrs or deformities. If significant damage is present, discontinue use and replace the chisel. Ensure proper seating and avoid twisting the chisel while in operation.
