Chasers (Thread)

Category: Machine Shop

Summary: recutting threads.

Thread chasers are specialized tools used to clean up or repair damaged or worn internal or external screw threads. Unlike taps and dies, which are used to *cut* new threads, chasers are designed to *restore* existing threads without removing significant material. They essentially "chase" along the existing thread grooves, correcting any imperfections or debris that may be obstructing proper fit. Chasers come in various sizes and thread standards to match the specific thread being worked on, and they are valuable tools in maintenance and repair applications to salvage threaded components and ensure proper assembly.
