CS106D74 - Koike 106D7 Size 4 High Speed Propane Cutting Tip

High-Performance Industrial Cutting with Koike 106D7-4

The Koike 106D7-4 High-Speed Divergent Cutting Tip represents the pinnacle of oxy-fuel cutting technology for industrial applications utilizing Propane or Natural Gas. Engineered for heavy-duty fabrication environments, this tip is designed to significantly reduce production time while maintaining superior cut quality. The "D7" series is renowned for its divergent orifice design, a sophisticated engineering feature that accelerates the cutting oxygen stream to supersonic velocities (Mach 2 or greater). This increase in velocity allows the operator to increase travel speeds by up to 30% compared to standard straight-bore tips, translating directly to reduced labor costs and increased throughput.

Specifically sized as a #4 tip, this model is optimized for cutting mild steel plates ranging from 2 inches to 3 inches (approx. 50mm to 75mm) in thickness. It is an ideal choice for structural steel fabrication, scrap processing, and heavy equipment manufacturing where thick plate cutting is routine. The tip features a robust copper outer shell for effective heat management and a specialized stainless steel inner liner. This liner is critical for maintaining the integrity of the gas flow and preventing the adhesion of spatter inside the tip, which is a common cause of flashbacks and premature failure in lesser quality nozzles.

At Josef Gas, we understand that gas efficiency is as important as cutting speed. The Koike 106D7-4 is calibrated to optimize the consumption of Propane or Natural Gas, providing a hot, stable preheat flame without wasting fuel. The resulting cut is characterized by a narrow kerf, sharp top edges, and minimal slag adherence at the bottom of the plate, reducing the need for secondary grinding or machining. Whether you are retrofitting an automated cutting table or upgrading hand torches, the 106D7-4 delivers consistent, high-velocity performance that modern industry demands.
