Frequently Asked Questions

What is a CHICAGO-LATROBE spiral point tap used for?

A CHICAGO-LATROBE spiral point tap is used for through-hole threading in metalworking. Its spiral point pushes chips ahead, preventing clogging. Common in automotive, aerospace, and general machining for creating clean internal threads in steel, aluminum, and alloys.

What are the specifications of the CHICAGO-LATROBE 358494 tap?

The CHICAGO-LATROBE 358494 is a 1/4"-20 UNC spiral point tap with H13 / 2B tolerance, 2 flutes, plug chamfer, and high-speed steel construction. It is an oversized tap designed for producing threads in harder materials where standard taps may not achieve the required fit.

Where to buy CHICAGO-LATROBE taps in worldwide?

3G Electric supplies CHICAGO-LATROBE taps worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on the 358494 or other CHICAGO-LATROBE tooling.

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

Select a tap based on thread size (e.g., 1/4"-20 UNC), material hardness, and hole type. For through holes, a spiral point tap like the CHICAGO-LATROBE 358494 pushes chips forward. For blind holes, use a spiral flute tap. Match the H limit (e.g., H13) to your required thread class.
