Frequently Asked Questions

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

The CHICAGO-LATROBE Spiral Point Tap is used for threading blind or through holes in metal, particularly in production environments. Its spiral-point design pushes chips forward, reducing clogging. It is ideal for tapping 3/8"-16 UNC threads in materials like steel, aluminum, and cast iron.

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

The CHICAGO-LATROBE Spiral Point Tap has a 3/8"-16 UNC thread size, H2 / 2B tolerance, 3 flutes, and a plug chamfer. It is made of high-speed steel (HSS) for durability. The manufacturer part number is 357504. This tap is designed for general-purpose threading in metalworking applications.

Where to buy CHICAGO-LATROBE taps in worldwide?

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

To select the right CHICAGO-LATROBE tap, match the thread size (e.g., 3/8"-16 UNC), chamfer type (plug for general use), and material (HSS for steel). Consider hole type: spiral-point taps push chips forward, ideal for through holes. For blind holes, consider spiral-flute taps. Always verify tolerance class (H2 / 2B) for fit.
