Frequently Asked Questions
What is the OSG Extension Tap M5x0.8 used for?
The OSG Extension Tap M5x0.8 is used for threading blind or deep holes in metal parts where a standard tap cannot reach. Its extended length allows access to recessed areas in automotive, aerospace, and general machining applications. The 2-flute spiral-point design pushes chips forward, reducing clogging.
What are the specifications of the OSG Extension Tap M5x0.8?
This OSG extension tap has a metric M5x0.8 thread size, a D4 / 4H-6H tolerance class, 2 flutes, a plug chamfer, and is made from black oxide high-speed steel. The manufacturer part number is 1111800501. It is designed for through-hole or blind-hole threading in steel and non-ferrous materials.

How to select the correct OSG extension tap for deep hole threading?
To select the correct OSG extension tap, match the thread size (M5x0.8) and tolerance class (D4 / 4H-6H) to your workpiece material and hole depth. Ensure the tap's reach exceeds the hole depth. For blind holes, use a plug chamfer; for through holes, a bottoming chamfer may be preferred. Consult OSG's technical data for material-specific speeds.
