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 metal, particularly in production environments. Its TiN coating reduces friction and extends tool life, while the plug chamfer and 3-flute design help clear chips forward, making it suitable for high-speed tapping in steel and alloys.

What are the specifications of the OSG spiral point tap 1241605?

The OSG spiral point tap has a 3/8"-16 UNC thread size, H5 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is made of TiN coated high speed steel. The manufacturer part number is 1241605. This tap is designed for general purpose threading in ferrous materials.

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 1241605 tap.

How to select the right OSG spiral point tap for a job?

Select the OSG spiral point tap based on thread size (e.g., 3/8"-16 UNC), material (TiN coated HSS for steel), and hole type (plug chamfer for through holes). Match the H5 tolerance to your required thread class (2B-3B). For blind holes, consider a spiral flute tap instead.
