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 design pushes chips ahead, preventing clogging. This M8x1.25 metric tap with a plug chamfer is ideal for production tapping in steel, aluminum, and alloys where clean threads and high throughput are required.

What are the specifications of the CHICAGO-LATROBE 313516 tap?

The CHICAGO-LATROBE 313516 is an M8x1.25 metric oversized spiral-point tap with a D11 / 6H thread class, 3 flutes, and a plug chamfer. It is made of high-speed steel (HSS) and is designed for through-hole tapping. The oversized D11 tolerance provides a slightly larger thread for coating or special fits.

How to select the correct oversized tap for metric threads?

Select an oversized tap like the CHICAGO-LATROBE D11 / 6H when you need a thread that accepts a coating (e.g., TiN) or when mating parts require a looser fit. Verify the thread pitch (M8x1.25), chamfer type (plug for through-holes), and material (HSS for general steel). Always test on a sample workpiece first.
