This holder is designed primarily for Right Angle Tools enabling them to rotate freely clamped to a large needle bearing assembly, flanked by 2 thrust bearing assemblies and completely encased in a precisely machined aluminum housing with 50mm (1.96″) ID clearance for the tool handle.
Once clamped the Right Angle tool can rotate freely without torque reaction.

NB-TH weighs 2.6 lbs (1.18 Kg) so it is compatible with 815, 1015 and 1025 frames only.
This holder is a semi-custom holder, typically needing additional engineering for your application.
