Frequently Asked Questions

What is the OSG Extension Tap M12x1.5 used for?

The OSG Extension Tap M12x1.5 is used for threading blind holes and deep cavities in multiple materials, including steel and aluminum. Its extended reach and spiral-point design push chips forward, making it ideal for production environments where standard taps cannot access the workpiece.

What are the specifications of the OSG Extension Tap M12x1.5?

This OSG tap has a metric M12x1.5 thread size, a D6 / 4H-6H tolerance, and a plug chamfer with 3 flutes. It features a V coating on powdered metal for wear resistance. The manufacturer part number is 1653006508.

Where to buy the OSG Extension Tap M12x1.5 worldwide?

You can source the OSG Extension Tap M12x1.5 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct OSG tap for your threading application.

How to select the correct OSG extension tap for deep hole threading?

To select the correct OSG extension tap, match the thread size (M12x1.5), tolerance class (D6 / 4H-6H), and chamfer type (plug) to your hole depth and material. For deep holes, ensure the tap's reach exceeds the hole depth. OSG's V-coated powdered metal taps suit harder materials.
