SCT’s DH Holders are engineered for use with our single point tools and provide a round, flat-free shank for flexible mounting in collet or round-style tool holders. Constructed from heat-treated steel and secured with two lock-down screws, DH Holders offer excellent rigidity and performance for a wide range of turning applications.
