Frequently Asked Questions

What is the CHICAGO-LATROBE Spiral Point Tap 280405 used for?

This CHICAGO-LATROBE spiral point tap is designed for threading blind holes in ferrous and non-ferrous materials. Its 1/4"-28 UNF size and plug chamfer make it suitable for general-purpose tapping in manufacturing and maintenance applications where chip evacuation is critical.

What are the specifications of the CHICAGO-LATROBE 280405 tap?

The CHICAGO-LATROBE 280405 is a spiral point tap with a 1/4"-28 UNF thread, H3 / 2B tolerance, 3-flute design, and plug chamfer. It is a general-purpose tap for through-hole or blind-hole threading in steel, aluminum, and other machinable alloys.

Where to buy CHICAGO-LATROBE taps in worldwide?

3G Electric supplies CHICAGO-LATROBE taps worldwide, handling full logistics, customs clearance, and delivery to your facility. As a global industrial distributor since 1990, we source and deliver this 280405 spiral point tap to procurement teams and maintenance shops internationally.

How to select the correct CHICAGO-LATROBE tap for a job?

Select a tap based on thread size (e.g., 1/4"-28 UNF), material type, and hole configuration. For blind holes, a spiral point tap like the CHICAGO-LATROBE 280405 pushes chips forward. Match the chamfer (plug, bottoming, or taper) to hole depth and tolerance (H3/2B) for fit requirements.
