Morse Taper Sleeves and Extensions
Overview

Product description
Choose a Morse taper sleeve by its two connections: the male taper that fits the machine and the female taper that receives the tool. A reduction sleeve changes the connection size; an extension also changes the reach. Include the required length and tang, thread or other retention features so the proposed adapter can be checked against your setup.
Reduction or extension
State whether the requirement changes taper size, reach or both.
Retention details
Include tang, thread or other end geometry as shown on the actual tool drawing.
Write the connection from the machine to the tool
For a machine with an MT3 socket holding an MT2-shank tool, the reducing sleeve needs an MT3 male outside and an MT2 female inside. Reversing those labels describes a different requirement. This example explains direction; it does not confirm a stocked FuRui configuration.
Use this order in an inquiry: machine socket → sleeve male taper → sleeve female taper → tool shank. Add the tool-end tang or thread and the machine’s retention/removal arrangement. A taper number describes fit, but does not by itself establish that the assembly is retained correctly for the intended operation.
Terminology reference: the RÖHM reducing-sleeve catalog lists external and internal Morse tapers separately. Its dimensions and material ratings are not specifications for this FuRui series.
Reducing size and extending reach are different requirements
A reducing sleeve adapts a smaller tool taper to a larger machine socket. An extension moves the receiving connection farther from the machine and may also change taper size. Overall length and added projection are not necessarily the same measurement because part of the adapter is inside the machine socket.
Send a side-view sketch showing the machine face, required tool-tip position and any clearance obstruction. Identify the shortest practical reach for the job and check the complete assembly rather than treating additional length as free clearance. Include the old sleeve’s two end views and markings when replacing an existing setup.
Request a sleeve or extension match. If the machine side is BT rather than Morse taper, compare BT MTA and BT MTB adapters instead.

Application scenarios
Typical selection contexts for this series, not customer project claims. Confirm machine compatibility and cutting conditions for your setup.
Taper-size conversion
Matching a documented tool taper to the required machine-side connection.
Tool reach adaptation
Reviewing an extension where additional reach is needed in an approved setup.
Workshop maintenance
Replacing a known sleeve using its two taper designations and overall length.
Inspection & order review
Specify the dimensions, tolerances and records your order requires. Acceptance criteria must be agreed for the selected model.
Drawing information to provide
- Input taper
- Output taper
- Length
Check the drawing reference faces and units. A catalog size alone does not define a tolerance or an inspection method.
Records to request
List any required dimensional report, material document or model identification photograph in your inquiry. Confirm availability and scope in the quotation.
For a drawing-based part, include the drawing revision and identify the critical dimensions. Website photographs are not inspection reports.
Packaging & delivery
Agree the packing method and photo requirements when confirming your order.
Order-specific photo confirmation
No verified shipment photographs for this series are currently published. Include selected-model, protective-packing and outer-label photos in your order requirements.
Discuss packing requirementsPhotos to confirm before dispatch
Use this checklist to agree what should be documented for your selected model.
- Male-to-female taper direction clearly labeled
- Both internal and external tapers protected
- Extension length matched to the approved drawing
Stock, dispatch date and shipping method are confirmed with the quotation. Website images are not live inventory evidence.

Models and specificationsIs MT3 to MT2 enough to identify the adapter direction?
Write both genders and their roles. For an MT3 machine socket receiving an MT2 tool, the sleeve is MT3 male outside and MT2 female inside. Confirm retention and length separately; the example is not a stock declaration.
Are a reduction sleeve and an extension the same item?
No. Reduction changes the taper-size connection, while an extension also changes tool reach. State overall length and the required projection from the machine reference face; they are not necessarily the same measurement.
Can any taper-shank tool be used after adding a sleeve?
Confirm retention, end geometry, engagement and the machine's operation requirements as a complete setup.
Can you match a worn unmarked sleeve?
Photograph both ends and any markings, then provide the measured length and taper details. Identify which end fits the machine and which receives the tool. If the part is worn, include the original tool or machine drawing where available.
