Product Description

The OSG Extension Tap is a spiral-point extension tap in M6x1 metric size, designed for threading applications. It features a D5 / 4H-6H tolerance, plug chamfer, black oxide high-speed steel construction, and 2 flutes (MPN 1111800601).

Frequently Asked Questions

What is the OSG Extension Tap M6x1 used for?

The OSG Extension Tap M6x1 is used for threading blind or through holes in metal parts where standard taps cannot reach. Its extended length allows access to deep or recessed areas in automotive, aerospace, and general machining applications. The spiral-point design pushes chips forward, reducing clogging.

What are the specifications of the OSG Extension Tap M6x1?

This OSG tap has a metric M6x1 thread size, a D5 / 4H-6H tolerance class, 2 flutes, a plug chamfer, and is made from black oxide high-speed steel. The manufacturer part number is 1111800601. It is designed for threading in steel and cast iron.

Where to buy the OSG Extension Tap M6x1 worldwide?

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

To select the correct OSG extension tap, match the thread size (e.g., M6x1) and tolerance class (e.g., D5 / 4H-6H) to your hole specifications. Consider material hardness—black oxide HSS suits steel. Choose plug chamfer for blind holes. Verify reach length needed for deep applications.
