Frequently Asked Questions
What is an OSG extension tap used for?
An OSG extension tap is used to cut internal threads in hard-to-reach or deep-hole applications across multiple materials. Its extended reach and spiral-flute design aid chip evacuation, making it suitable for machining, automotive, and general industrial maintenance where standard taps cannot access the workpiece.
What are the specifications of the OSG M18x2.5 extension tap?
This OSG extension tap has a metric M18x2.5 thread size, a D7 / 4H-6H tolerance class, 4 flutes, and a modified bottoming chamfer. It is designed for threading multiple materials and is identified by manufacturer part number 1652008308. The spiral-flute geometry helps clear chips during operation.

How to select the right OSG extension tap for deep-hole threading?
Select an OSG extension tap based on thread size (e.g., M18x2.5), material type, and required reach. The spiral-flute design and modified bottoming chamfer suit blind holes and chip evacuation. Match the tolerance class (D7 / 4H-6H) to your thread fit requirement. Consult OSG technical data for speed and feed recommendations.
