CS106D72 - Victor CutSkill 106D7-2 Propane Cutting Tip Size 2

High-Performance Divergent Cutting Technology

The Victor CutSkill CS106D72 is a precision-engineered cutting tip designed to meet the rigorous demands of industrial metal fabrication. Modeled after the industry-standard Koike 106D7 series, this tip utilizes a high-speed divergent bore design specifically optimized for alternative fuels such as Propane and Natural Gas. Unlike standard straight-bore tips, the divergent design expands the cutting oxygen stream as it exits the nozzle, maintaining a high velocity that clears molten slag efficiently while preserving a narrow kerf. This results in superior cut quality with minimal dross adhesion, reducing post-cut grinding and cleanup time.

This specific model is a Size 2, which is typically calibrated for cutting mild steel ranging from approximately 1/2 inch to 1 inch (12mm to 25mm) in thickness. The internal geometry of the tip is critical for maintaining flame stability; the Victor CutSkill series employs a stainless steel liner and heavy-duty shell to resist heat deformation and wear. The splines are machined to exact tolerances to ensure a uniform preheat flame ring, which is essential for quick starts and consistent travel speeds, particularly when using slower-burning fuel gases like propane.

For industrial MRO operations, standardization is key. The CS106D72 offers seamless compatibility with existing Koike-style torches, allowing facilities to leverage Victor's manufacturing quality without replacing their entire torch inventory. Whether used in automated track cutting machines or hand-held torches, this tip delivers the thermal efficiency required for heavy plate processing. The use of propane or natural gas with this tip style is often preferred in heavy industry due to the lower cost of fuel gas compared to acetylene, and the 106D7 design ensures that this cost saving does not come at the expense of cutting speed.

Technical Specifications and Application

The CS106D72 is constructed with a focus on gas flow dynamics. The high-speed curtain of the preheat flame protects the cutting stream from atmospheric contamination, ensuring the oxygen purity remains high at the point of contact with the steel. This is crucial for maintaining the exothermic reaction required for deep cuts. Operators should consult standard Koike-style cutting charts for precise pressure settings, typically involving higher oxygen pressures to take full advantage of the divergent nozzle's capabilities.
