Frequently Asked Questions

What is the OSG Extension Tap M3.5x0.6 used for?

The OSG Extension Tap M3.5x0.6 is designed for threading blind or deep holes in multiple materials, including steel and aluminum. Its 3-flute spiral-point design pushes chips forward, reducing clogging. The V coating and powdered metal construction provide wear resistance for extended tool life in production environments.

What are the specifications of the OSG Extension Tap M3.5x0.6?

This OSG tap has a metric thread size of M3.5 with a 0.6 mm pitch, a D3 / 4H-6H tolerance class, and a plug chamfer. It features 3 flutes, a spiral-point design, and a V coating on powdered metal. The manufacturer part number is 1653001508.

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

Select the OSG extension tap based on thread size (M3.5x0.6), hole depth, and material. The D3 / 4H-6H tolerance suits general-purpose threading. For blind holes, the plug chamfer and spiral-point design help evacuate chips. Always match the tap coating (V coated powdered metal) to the workpiece hardness for optimal tool life.
