Product Description

The KNIPEX 9K 00 19 51 US is a 4-piece internal and external retaining ring pliers set designed for installing and removing snap rings in bore and shaft applications. The set covers bore sizes from 1/2 to 2-1/2 inches and shaft sizes from 3/8 to 2-1/2 inches, giving technicians a broad working range without switching to a different set. Tips are angled at 45 degrees, improving access in recessed grooves and tight housings. Tip diameters range from 0.053 to 0.07 inches to suit a variety of ring sizes. This set is suited for mechanics, millwrights, HVAC technicians, and other trade professionals who regularly work with retaining rings on motors, pumps, and related rotating equipment.

This set is appropriate for both residential and commercial service environments where snap ring work is routine. Common applications include motor shaft disassembly, pump bearing removal, and equipment rebuilds across HVAC, plumbing, and industrial maintenance contexts. The included pliers cover the most common bore and shaft sizes encountered in field and shop service, reducing the need to source individual pliers for different ring sizes.
