Techniks’ FID end mill holders are designed for improved chip evacuation, extended cutting tool life and high speeds and feed rates. The holders feature two internal coolant paths through the bore of the toolholder. These paths flood the tip of the cutting tool with coolant. The company says this offers manufacturers the benefits of coolant-thru capability without the need to purchase coolant-thru cutting tools.
The toolholders’ bore IDs are built to a tolerance standard of H5 to minimize runout. They are balanced to 10,000 rpm and come with lab certification for ID accuracy, taper accuracy and balance. The holders are compatible with CAT 40 spindles in sizes to fit tool shanks from ¼" to 1".
