Frequently Asked Questions
What is an OSG extension tap used for?
An OSG extension tap is used for threading blind holes in hard-to-reach areas of metal parts. Its extended reach and spiral-flute design clear chips efficiently, making it ideal for machining, automotive, and general manufacturing applications where standard taps cannot access the workpiece.
What are the specifications of the OSG M4.5x0.75 extension tap?
This OSG extension tap has a metric thread size of M4.5x0.75, with a D4 / 6H tolerance class. It features 3 flutes and a modified bottoming chamfer, allowing threading close to the bottom of blind holes. The manufacturer part number is 1652001908.

How to select the right OSG extension tap for a job?
Select an OSG extension tap based on thread size, pitch, and chamfer type. For blind holes, choose a modified bottoming chamfer like this D4 / 6H tap. Match the flute count and material coating to your workpiece—3-flute designs suit general-purpose threading in steel and aluminum.
