Tyrolit CCH25 Circular Wire Saw

Product Positioning: Circular Wire Saw Replacing Large Bore Drills

The CCH25 is a dedicated circular-opening machine in Tyrolit's modular wire-saw system, complementing linear saws like the WCE18/WCE30. Its job is not to slice a building in half but to cut clean circular openings in concrete walls, slabs or steel for pipework, stairwells, elevator shafts or equipment passages.

Compared with conventional large bore drills, a circular wire saw can cut thicker, harder sections with better wall quality and more flexibility, though single-hole setup takes longer and demands more operator skill.

Key Specs

The CCH25 uses a GR2 hydraulic motor, so it needs an external hydraulic power pack (typically from Tyrolit's modular pump station or a compatible on-site source). Hydraulic drive provides smooth torque during circular cutting and resists stalling when hitting rebar.

The 500–2500 mm diameter range covers ordinary pipe holes up to large equipment passages. Official examples: a 500 mm hole in 100 mm thick concrete needs about 4 m of wire; a 2500 mm hole in 600 mm thick concrete needs about 6.2 m. For large-diameter thick-wall jobs, wire consumption and perimeter management are key cost factors.

Cutting Performance and Use Cases

Because the CCH25 is a dedicated circular saw, its 'cutting depth' is expressed as hole diameter and wall thickness rather than the 'wire storage' of linear saws. The 500–2500 mm adjustable range is uniquely valuable for building retrofitting, bridge bearing replacement and nuclear-facility modification.

The enclosed wire guide is an important safety feature: during circular cutting the wire rotates at high speed and the guide prevents accidental detachment, protecting operators and surrounding structures. Quick wire threading and tensioning reduce downtime between holes.

Who It Suits: Building Retrofit, Specialty and Nuclear Decommissioning Contractors

If you frequently need large circular openings in concrete or steel—HVAC penetrations, elevator-shaft retrofits, nuclear equipment replacement passages—the CCH25 is a more flexible choice than large drills. It is compatible with the Tyrolit modular system and can reuse existing hydraulic packs and drill-rig brackets.

For straight-line demolition, stone quarrying or block squaring, the CCH25 is not suitable; choose a WCE series saw or a dedicated stone wire saw instead.

Four Pre-Purchase Reminders

• Confirm hydraulic power source: the CCH25 needs a GR2 hydraulic motor and power pack; verify flow, pressure and compatibility with existing equipment.
• Match hole diameter and wall thickness: different diameters and thicknesses require different wire lengths; estimate typical job consumption and confirm wire supply lead time.
• Supporting bracket/drill rig: circular cutting needs stable centering and feed mechanism; confirm whether it is included or requires an additional drill rig/bracket.
• Wire speed and weight to be confirmed: official specs omit wire speed, weight and dimensions; if the project has lifting, transport or platform load limits, request full documentation.
