Coolant Supply Options in Steep Taper Toolholders

Tech Tip: Techniks and Parlec

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 the Spindle
• Through the Flange Entry (DIN B)

Through Spindle Coolant Delivery

Through holes are standard in all Parlec and Techniks toolholders. Solid and through hole retention knobs are available to accommodate coolant and non-coolant applications. This is the most common method of coolant delivery.

The coolant is delivered from the spindle through the knob and exits through the cutting tool. Coolant through knobs are sold separately.

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". 

With Screws:Coolant delivered from the spindle through the knob and exits through the cutting tool. Coolant through knobs sold separately.

Without Screws:Coolant delivered from the spindle through the flange and exits through the cutting tool. Solid knob required. Solid knobs sold separately.

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
