If you work with ER32 collet chucks on lathes, milling machines, or CNC setups, this Shars collet wrench is a must-have tool! It's specifically designed to fit the slotted nuts on ER32 collets, making it easy to tighten or loosen them without slipping or stripping. The wrench has a 45–52mm open end, which matches standard ER32 nut sizes, and an overall length of 190mm (about 7.5 inches) for good leverage. It's made from thick, durable steel that can handle high torque without bending or warping, so you can get a solid grip even on stubborn nuts. The nose-type design lets you access tight spaces around the spindle or chuck more easily than a standard open-end wrench. Whether you're changing tools, swapping collets, or doing routine maintenance, this wrench saves time and effort. A simple, reliable tool that belongs in every machinist's toolbox. Keep your collets secure and your workflow smooth with this heavy-duty spanner.
