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 extended shank allows threading in locations where standard taps cannot reach, making it ideal for machining multiple materials like steel and aluminum.

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, 3 flutes, and a plug chamfer. It features a V coated powdered metal construction for durability and is identified by manufacturer part number 1653001908.

Where to buy OSG extension taps worldwide?

3G Electric supplies OSG extension taps worldwide, handling full logistics and customs clearance for global delivery. As a sourcing specialist across 14 industrial departments, we provide genuine OSG tooling and support procurement for international buyers.

How to select the right OSG extension tap for a job?

Select an OSG extension tap based on thread size, material, and reach required. For deep or obstructed holes, choose the appropriate shank length. Match the tap's coating and flute count to the workpiece material—V coated powdered metal taps suit harder materials for extended tool life.
