Frequently Asked Questions

What is the CHICAGO-LATROBE Spiral Point Tap 313559 used for?

This tap is used for threading through-holes in metal, especially steel and alloys. Its spiral-point design pushes chips forward, preventing clogging. It is ideal for production tapping in automotive, aerospace, and general manufacturing where clean UNC threads are required.

What are the specifications of the CHICAGO-LATROBE 313559 tap?

The CHICAGO-LATROBE 313559 is a 3/8"-16 UNC spiral point tap with H11/1B tolerance, 3 flutes, and a plug chamfer. It is an oversized tap for producing threads with slightly larger pitch diameter. The manufacturer part number is 313559.

Where to buy CHICAGO-LATROBE taps in worldwide?

3G Electric supplies CHICAGO-LATROBE taps worldwide. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on the 313559 spiral point tap.

How to select the right CHICAGO-LATROBE tap for my application?

Select based on thread size, material, and hole type. For through-holes, a spiral point tap like the 313559 pushes chips ahead. For blind holes, use a spiral flute tap. Match the tap tolerance (e.g., H11/1B) to your required thread class. Consult CHICAGO-LATROBE's technical data for material-specific speeds.
