Rohm Drill Sleeve - 3MT External x 2MT Internal

A Morse Taper is a standardized tapering system used for fitting tools (like drill bits and reamers) into the spindles of machine tools (like drill presses and lathes). It relies on friction to hold the tool securely in place.

You need to know the Morse Taper size of your machine's spindle (this will be the external size of the sleeve) and the Morse Taper size of the tool you wish to use (this will be the internal size of the sleeve). This product is specifically 3MT external x 2MT internal.

No, this sleeve is designed exclusively for Morse Tapers. Other taper systems like Jacobs Tapers or R8 tapers are not compatible.

Generally, stacking multiple drill sleeves is not recommended. Each additional sleeve can introduce more potential for runout, reduce rigidity, and compromise accuracy and safety. It is best to use a single sleeve if possible.

After cleaning, apply a thin layer of machine oil or rust preventative to the sleeve, especially if storing for an extended period. Keep it in a dry environment.

The Rohm Drill Sleeve is made from high-quality tool steel, ensuring durability and precision.

You can use any tool with a 2MT (Morse Taper #2) shank, such as drill bits, reamers, or counterbores, in a machine spindle that accepts a 3MT (Morse Taper #3) external fitting.

Ensure you are using the correct drift key for the spindle or sleeve slot. Insert the drift key and tap firmly but not excessively with a soft-faced mallet. Avoid twisting or prying.

Remove the tool and sleeve, thoroughly clean all mating taper surfaces (sleeve external, spindle internal, sleeve internal, tool shank external) of any oil, chips, or burrs. Reinsert, ensuring a firm, positive seating. Check if the tool shank or sleeve taper has been damaged.

Check that both the sleeve and the tool are properly seated in their respective tapers and that all surfaces are clean. Inspect the tapers for any damage or wear. Verify that the machine spindle itself does not have excessive runout.

Immediately stop operation. Remove and inspect both the sleeve's external taper and the machine spindle's internal taper for dirt, damage, or wear. If tapers are worn or damaged, replacement may be necessary to ensure a secure fit.
