Our DHF Holders are designed for use with our single point tools and feature a precision-ground flat for secure alignment in set-screw style tool blocks. Made from heat-treated steel and equipped with two lock-down screws, DHF Holders deliver maximum rigidity and consistent tool positioning—ideal for turning operations that demand stability and repeatability.
