Frequently Asked Questions

What is the OSG Extension Tap M10x0.75 used for?

The OSG Extension Tap M10x0.75 is used for threading blind or deep holes in multiple materials, including steel, stainless steel, and aluminum. Its extended reach and spiral-flute design efficiently evacuate chips, making it ideal for automotive, aerospace, and general manufacturing applications where standard taps cannot reach.

What are the specifications of the OSG Extension Tap M10x0.75?

The OSG Extension Tap has a metric M10x0.75 thread size, a D4 / 4H-6H tolerance class, and a modified bottoming chamfer. It features 3 spiral flutes for chip evacuation and is designed for threading multiple materials. The manufacturer part number is 1652004508.

Where to buy the OSG Extension Tap M10x0.75 worldwide?

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

To select the correct OSG extension tap, match the thread size (e.g., M10x0.75), tolerance class (D4 / 4H-6H), and chamfer type (modified bottoming) to your hole depth and material. For deep holes, choose a spiral-flute design for chip evacuation. Always verify the tap's reach exceeds the hole depth. 3G Electric can help source the right OSG tap for your application.
