Frequently Asked Questions

What is the OSG Straight Flute Tap 3111408 used for?

The OSG Straight Flute Tap 3111408 is designed for threading hardened steel. Its V coated carbide construction and modified bottoming chamfer allow it to cut threads in tough materials where standard taps wear quickly. Common applications include die and mold making, automotive components, and general machining of hardened workpieces.

What are the specifications of the OSG Straight Flute Tap 3111408?

This OSG tap has a 1/2"-13 UNC thread size with a 2B class of fit. It features 5 flutes, a modified bottoming chamfer, and V coated carbide construction. The manufacturer part number is 3111408. It is designed for threading hardened steel and provides good chip evacuation and wear resistance.

How to select the correct OSG tap for hardened steel?

For hardened steel, choose a tap with a carbide substrate and a wear-resistant coating like the V coating on this OSG tap. A modified bottoming chamfer allows threading close to the bottom of a blind hole. Ensure the thread size and class (e.g., 1/2"-13 UNC, 2B) match your application. Consult OSG's technical data for specific material hardness ranges.
