• Quarry & mining: Secondary reduction of oversize boulders before crushing.
• Road & pavement works: Asphalt and concrete road bed removal.
• Trenching & foundation work: Breaking through hardpan or shallow rock where trenching buckets struggle.
• Compatible with: SB131 hydraulic breakers mounted on 30‑35 ton excavators.

Q1: How is the flat end chisel different from a moil point?

A flat end chisel delivers a blunt, crushing force over a wide area. It excels in breaking concrete and layered rock where you want to fracture rather than penetrate. A moil point concentrates energy on a small point, making it better for drilling into hard, monolithic rock.

Q2: Is this chisel compatible with other breaker brands that use a 165mm diameter?

It is specifically machined for the SB131’s retaining pin and bushing system. While it may fit other 165mm‑class hammers, we recommend checking the lock‑notch dimensions and pin diameter before ordering. Contact our team with your hammer model for a compatibility check.

Q3: What causes premature chisel failure and how can I prevent it?

Common causes include blank firing (operating without pressing the chisel firmly against the material), prying with the chisel, and lack of lubrication. Always apply a high‑quality chisel paste every 2 hours, keep the chisel perpendicular to the work surface, and never use the chisel as a lever.

Q4: How do I install the 165mm flat chisel correctly?

Park the excavator on level ground, fully retract the breaker piston, and ensure the retaining pin area is clean. Slide the chisel into the front head until the lock notch aligns with the pin bore. Insert the retaining pin and secure it with the retaining ring or bolt. Apply grease before the first impact.
