Frequently Asked Questions
What gases are compatible with the 102-D7-2 tip?
This tip is designed for acetylene and oxygen systems commonly used in oxy-fuel cutting torches.
What is the cutting range for this size (#2)?
It’s optimized for steel plate thickness between approximately 15 and 30 mm (0.6–1.2 inches).
What does “D7” refer to in the model number?
The D7 designates Koike’s high-speed divergent oxygen flow tip series, engineered for greater cutting velocity and reduced gas use.
Are these tips compatible with non-Koike torches?
Yes. They fit most torches that accept Koike-style cutting tips. Always verify size and thread compatibility before use.
Are these tips factory-sealed?
They are unused new old stock—clean, uninstalled, and preserved in excellent condition.
Koike’s 102-D7-2 tips carry the precision of Japanese engineering and the reliability of proven oxy-fuel design. Ready from storage, they’ll return to doing what they were built for—cutting steel with speed and certainty.
