Cembre CY270L 27mm Broach Cutters, Tin Coated, for Rail Drilling Machines

The Cembre CY270L 27mm Broach Cutters, Tin Coated, are high-precision, long-range cutting tools designed for use with Cembre’s rail drilling machines, such as the LD-41P, LD-16B-RP, or LD-1P ECO. Engineered for railway applications, these broach cutters are optimized for drilling clean, accurate 27mm holes in steel rails, particularly VIGNOLE (flat-bottom) rails like the 60E1 (UIC60), with enhanced durability and efficiency for deeper drilling tasks.

Key Features

• 27mm Diameter: Ideal for drilling precise 27mm holes in rail webs, suitable for electrical contact installations, signal track circuits, or rail fastening systems requiring larger-diameter holes.
• Titanium Nitride (TiN) Coating: Enhances hardness, reduces friction, and improves corrosion resistance, delivering better cut surface finish and extended tool life under demanding conditions.
• Long-Range Design: The "L" designation indicates a longer cutting depth (likely 50 mm or greater), accommodating thicker rails or deeper holes compared to standard CY series cutters.
• Quick Push/Turn Shank: Ensures fast, secure attachment to Cembre rail drilling machines, streamlining setup and operation.
• Optimized Cutting Geometry: Produces clean, burr-free holes with faster drilling times and superior surface finish compared to earlier A and A-L type cutters.
• High Performance: Capable of drilling steel rail quality grades 700-900-1100 (UIC 860.0), offering more holes per cutter with improved efficiency and precision.
• Compatibility: Designed for Cembre rail drilling machines, ensuring seamless integration and reliable performance in lightweight, single-operator setups.
• Coolant System Support: Compatible with Cembre’s coolant systems (e.g., VASCO5000 lubrocooler, V11 antifreeze) with a reservoir and pump via quick coupler, enhancing cutting performance and tool longevity.
