Taper Adapters

Taper Adapters — New & Used

Taper adapters enable precise mounting of cutting tools, taps, reamers, and accessories into spindles, drill chucks, or collets by converting between different taper standards (e.g., Morse, Jacobs, CAT, or other types). These adapters maintain accurate alignment, improve tool life, and support flexibility across machines.

At Surplus Select, we carry a variety of new and used OEM taper adapters — including Morse-to-Jacobs, CAT-to-collet, taper reducers, and quick-change tap holders — offering compatibility for drill presses, CNC mills, lathes, tapping heads and manual rigs. Surplus pricing provides machinists, maintenance shops and production facilities an affordable way to support diverse tooling needs.
