More questions buyers ask
What is a hydraulic rock breaker chisel?
A hydraulic rock breaker chisel is a tool used with excavators and other machinery to break down large rocks, concrete, and other hard materials. It transfers the hydraulic hammer's impact energy to the breaking surface.
What is the material of the Pentagon chisels?
These Pentagon chisels are manufactured from high-quality 40Cr / 42CrMo alloy steel, known for its strength, toughness, and resistance to wear and tear in heavy-duty applications.
What is the hardness rating of these chisels?
The chisels are heat-treated to achieve a surface hardness of HRC 50–55, which provides excellent wear resistance and a long service life even under harsh conditions.
What does 'forged & quenched' mean?
This refers to the manufacturing process where the steel is heated and shaped (forged) and then rapidly cooled (quenched). This process enhances the steel's strength, durability, and resistance to impact.
What applications are these chisels suitable for?
They are ideal for a range of applications including construction, demolition, quarrying, and road work. They can efficiently break hard rock, concrete structures, and asphalt.
How do I maintain my rock breaker chisel?
Proper maintenance includes regular lubrication, inspecting the tip for wear or cracks, and ensuring it is correctly installed. Storing it in a dry place prevents corrosion.
Are these chisels compatible with all rock breakers?
No, compatibility depends on the breaker model. The 68mm chisel is for SB40 class breakers, and the 75mm chisel is for SB43 class breakers. Always check your equipment's specifications.
What is the difference between a wedge and moil point chisel?
A wedge chisel, like these, is used for cutting and trenching. A moil point chisel has a pointed tip and is used for general-purpose breaking and demolition of rock or concrete.
Do you provide a GST invoice?
Yes, we provide a GST invoice for all purchases, allowing you to claim input tax credit.
Is there a warranty on these chisels?
Yes, these chisels come with a manufacturer's warranty against manufacturing defects. Please refer to our warranty policy for more details.
Who should choose the Pentagon 68mm rock breaker chisel?
The 68mm chisel is best suited for users with an SB40 class hydraulic breaker. It is a cost-effective choice for general-purpose demolition, trenching, and breaking light rock or concrete.
Who should choose the Pentagon 75mm rock breaker chisel?
The 75mm chisel is designed for SB43 class breakers. Its larger diameter and heavier weight make it more effective for breaking harder rock and reinforced concrete in more demanding construction or demolition projects.
What is the main difference between the 68mm and 75mm chisels?
The primary differences are the diameter, weight, and compatibility. The 75mm chisel is larger, heavier, and designed for more powerful SB43 class breakers, while the 68mm chisel is for the smaller SB40 class.
Which chisel is better for heavy-duty demolition?
The 75mm chisel is the better choice for heavy-duty demolition as it is designed for more powerful breakers (SB43 class) and its greater mass delivers more impact energy to the target.
How does the chisel diameter affect performance?
A larger diameter chisel generally has more mass and a larger contact area. This allows it to deliver more force and break harder, larger materials more effectively, but it requires a more powerful hydraulic breaker to operate.
