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. The M14x1.5 metric size with a modified bottoming chamfer allows threading close to the bottom of a blind hole, making it ideal for maintenance, repair, and production across multiple materials.

What are the specifications of the OSG M14x1.5 extension tap?

This OSG extension tap has a M14x1.5 metric thread, D6 / 4H-6H tolerance, 3 flutes, and a modified bottoming chamfer. The spiral-flute design aids chip evacuation in multiple materials. The manufacturer part number is 1652007008.

Where to buy OSG extension taps worldwide?

How to select the right OSG extension tap for deep-hole threading?

Select an OSG extension tap based on thread size, pitch, chamfer type, and flute design. For blind holes, a modified bottoming chamfer like this M14x1.5 tap allows threading closer to the bottom. Match the tap tolerance (D6 / 4H-6H) to your required thread class and material.
