Why Choose the Merit Chisel for Rammer 2577?
The Rammer 2577 is known for its high-impact energy. A low-quality tool will “mushroom” or snap, causing downtime. Merit tools are designed to handle the load:
1. Vacuum Heat Treatment
Our chisels undergo a controlled vacuum heat treatment process. This creates a deep-case hardness that resists blunting and wear, while the internal core remains ductile. This “flexible strength” prevents the tool from snapping when subjected to the intense vibrations of the 2577.
2. Forged for Structural Integrity
Unlike cheaper rolled-steel alternatives, Merit tools are fully forged. This process aligns the molecular grain of the steel with the shape of the tool, dramatically increasing resistance to fatigue cracks and longitudinal splitting.
3. Precision Machined Shank
The shank of the Rammer 2577 chisel is machined to exact tolerances. This ensures a perfect fit within the upper and lower bushings, preventing “piston scuffing” and ensuring that 100% of the hammer’s energy is transferred through the center of the tool.
Available Tool Types
- Moil Point (Пика): Best for general demolition and soft/medium rock.
- Chisel (Клин): Ideal for trenching and directional breaking in sedimentary rock.
- Blunt (Тупой): Best for secondary breaking in quarries (boulder busting).
- Pyramid Point: High-penetration specialist for reinforced concrete and hard rock.
Maintenance Tip: Avoid “Blank Firing”
To protect your Rammer 2577 chisel and the internal tie rods:
- Apply Down-Pressure: Always ensure the tool is firmly pressed against the material before activating the hammer.
- Stop Immediately: Once the material breaks, stop the hammer to avoid “blank firing,” which sends destructive shockwaves back into the hammer body and can snap the tool at the retainer notch.
- Grease Every 2 Hours: Use high-quality Moly-Chisel Paste to prevent the tool from seizing inside the bushings.
