Ingco KC1601 Drill Chuck Key for 3-16mm Chucks, 1/2-20UNF
TSh 30,000
Our review
This is a replacement chuck key, the small geared tool used to tighten or loosen the jaws on a drill chuck. It suits anyone whose original key has gone missing, worn its teeth, or bent, and who needs to keep a 3-16mm chuck working. The connection size is 1/2-20UNF, so before buying, check the marking on your chuck or measure the pilot hole and count the teeth on your old key, since a key that looks similar but has the wrong thread or tooth count will not grip properly. The pack contains one key in double blister packaging. Compared with generic keys of unknown origin, buying a branded Ingco part gives you a known model number to match against your chuck, though you should still confirm the size rather than assume it fits every drill.
