BT30 × ER20 Tool Holder — 70mm, Without Slots

The Schmidt TE06106W is a BT30-taper to ER20 collet chuck arbor, 70mm long, without slots. This adapter mounts ER20 collets directly in a BT30 taper spindle, combining the universal availability of ER collets with the secure positive-drive engagement of a BT taper tool holder. The 70mm gauge length affects the tool stickout and rigidity at the spindle face. Slot variants (with/without slots) relate to ATC compatibility; verify whether the machine’s ATC requires slotted or smooth arbors before ordering. Use with the appropriate ER20 collet series for the tool shank diameter required.
