Frequently Asked Questions

What is the CHICAGO-LATROBE Spiral Point Tap used for?

The CHICAGO-LATROBE Spiral Point Tap is used for threading blind holes in production environments. Its spiral-point design pushes chips forward, making it ideal for through-hole tapping in materials like steel and aluminum. Common applications include automotive, aerospace, and general manufacturing where precise UNF threads are required.

What are the specifications of the CHICAGO-LATROBE Spiral Point Tap?

This tap has a 1/4"-28 UNF thread size with H3 / 2B tolerance, 3 flutes, and a plug chamfer. It is made from high-speed steel (HSS) for durability. The manufacturer part number is 282405, and it is designed for general-purpose tapping in ferrous and non-ferrous materials.

Where to buy CHICAGO-LATROBE taps in worldwide?
