„Dual Contact"-Face tooling used on Taper-Face spindles achieve additional contact between spindle s face and holder s flange (vs. face/flange clearance with conventional steep taper fittings).

Advantages:

Higher pulling forces (compared to classic spindles) achieve flange contact with pressure, complementary to the taper fitting.
Higher rigidity particularly profitable to long tooling and machining in difficult materials.
Higher run-out precision and axial (length) repeatability.

Taper-Face tooling can be used on conventional steep taper spindles but losing the face contact advantages.
