Features

This set includes an inner collet and a replacement wrench designed to replace the standard φ3.0 mm or φ2.35 mm inner collet built into the precision handpieces of the HP-250, HP-350D, HP-200S, and HP-300 precision handpiece grinders. Therefore, it allows you to upgrade your existing configuration to support a dedicated φ1.6 mm shaft system. Because the components are engineered for precise compatibility, they ensure secure installation and stable performance without modification.

Moreover, this conversion kit transforms your precision handpiece into a specialized φ1.6 mm model. As a result, you gain enhanced control and improved accuracy for fine-detail work. Instead of limiting your setup to larger shaft sizes, you simply install the new inner collet and expand your application capabilities immediately.

By converting to a dedicated φ1.6 mm configuration, you improve precision handling, increase workflow flexibility, and maintain consistent performance in delicate grinding, polishing, and finishing operations.
