Say Goodbye to slug damage with the The SlugKeeper™ by DTC Products. DTC Products' Slug Retention Machine (patented) uses a pneumatically-powered grinder to precisely machine a small angled groove into the sidewall of the die cavity in a stamping die. A micrometer coupled to the drive of the machine’s slide enables precise movement of the machine’s carriage to enable the depth of the slug retention groove to be precisely controlled.
