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 efficiently evacuate chips, making it ideal for machining, automotive, and general manufacturing where standard taps cannot access the workpiece.

This OSG extension tap has a metric M5x0.5 thread size, a D3 / 4H-6H tolerance class, and a modified bottoming chamfer. It features 3 spiral flutes for chip evacuation and is designed for threading multiple materials. The manufacturer part number is 1652002008.
Where to buy OSG extension taps worldwide?

How to select the correct OSG extension tap for deep-hole threading?
Select an OSG extension tap by matching the thread size (e.g., M5x0.5), tolerance class (D3 / 4H-6H), and chamfer type to your application. For deep holes, ensure the tap's reach exceeds the thread depth and that the spiral-flute design matches the material being threaded to prevent chip clogging.
