Getting coolant through the toolholder and to your cutting tool can be accomplished in two ways with Parlec and Techniks toolholders. Coolant is delivered from the spindle by two methods:
Through-Flange/ DIN B Coolant Delivery
Combined with solid retention knobs "Through the Flange" holes go through the flange to deliver the coolant from the spindle.
This is sometimes referred to as "DIN B" or "Form B".
Through Flange/ Form B is an available standard for many tools and available as a standard modification for most toolholders.
Form B convertible or AD/B (BC) is available in many sizes. The AD/B (BC) style can be used as either through the spindle , as supplied, or converted to Form B, through the flange. Flange entry is enabled by removing two screws
