Frequently Asked Questions

What is the OSG spiral point tap used for?

The OSG spiral point tap is used for threading blind or through holes in ferrous and non-ferrous materials. Its TiN coating reduces friction and extends tool life, making it suitable for general-purpose tapping in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG spiral point tap 1240005?

The OSG spiral point tap has a 1/4"-20 UNC thread size, H5 tolerance for 2B-3B class fit, 2 flutes, plug chamfer, and TiN coated high speed steel construction. The manufacturer part number is 1240005. It is designed for general-purpose tapping in production environments.

Where to buy OSG spiral point taps worldwide?

You can source OSG spiral point taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the OSG 1240005 tap.

How to select the correct OSG spiral point tap for my application?

Select the OSG spiral point tap based on thread size (1/4"-20 UNC), material type, and hole configuration. For through holes, spiral point taps push chips forward. The TiN coating suits ferrous materials. Match the H5 tolerance to your required thread class (2B-3B). Consult OSG's technical data for optimal speeds and feeds.
