Adapt your MT3 machine spindle to accept MT2 tooling. This Morse Taper sleeve (MT3 → MT2) is precision-ground and hardened for accurate, concentric seating of arbors, drill chucks and centers on drill presses, lathes (tailstocks) and mills in drilling mode.
Extra Information
Clean and degrease both the spindle and sleeve before installation to maximize holding power.
Seat by hand pressure on a solid support; avoid hammering on precision surfaces.
Remove using the machine’s eject feature or a correct taper drift where applicable.
Pro Tip
Mark a small witness line across spindle, sleeve and tool shank; reassembling to the same orientation can help preserve best concentricity.
If insertion feels rough, lightly stone only raised burrs—never sand or file the taper surfaces.
Features
Reduction sleeve: converts MT3 female spindle to MT2 female bore.
Precision-ground tapers for low run-out and reliable repeatability.
Hardened steel construction for durability in workshop environments.
Smooth finish for clean seating and easy release.
Industry-standard Morse geometry for wide tooling compatibility.
Benefits
Versatility: run MT2 accessories (chucks, centers, arbors) on MT3 machines.
Accuracy: concentric fit helps improve hole quality and surface finish.
Convenience: quick tool changes without swapping the machine arbor.
Safety
Disconnect power before fitting or removing sleeves, chucks or arbors.
Ensure tapers are fully seated; avoid side-loading small drills.
Use rotary drilling only—do not use hammer/impact with taper-mounted tooling.
