OSG Extension Tap: M10x1.5 Metric, D6 / 4H-6H, 3 Flute, Plug Chamfer

An OSG extension tap is used to cut internal threads in deep or hard-to-reach holes. The extended reach allows threading in recessed areas, such as engine blocks or hydraulic manifolds, where standard taps cannot access. It is common in automotive, aerospace, and general machining applications.

This OSG extension tap has a metric M10x1.5 thread, D6 / 4H-6H tolerance, 3 flutes, plug chamfer, and is made from black oxide high speed steel. The manufacturer part number is 1111801001. It is designed for through-hole threading with a spiral-point geometry to push chips ahead.

Select an OSG extension tap based on thread size (e.g., M10x1.5), material (black oxide HSS for steel), chamfer type (plug for through holes), and reach length. Ensure the tap's tolerance class (D6 / 4H-6H) matches your thread fit requirement. For deep holes, verify the extension length clears the obstruction.
