2. Metal Disintegrators or MDM machines are manufactured
for the specific purpose of removing broken tools from
work pieces. The metal disintegration process removes a
tap, bolt or drill leaving the hole intact and allowing a part
to be reclaimed.

3. MDM uses a spark erosion
process commonly used for
destructive cutting. Typical
application includes broken
tool extraction (taps, drills,
reamers, drill bits)
metallurgical sample
excavation and bolt removal.
There is no faster or efficient
or cost effective method to
remove broken tools, studs
or fasteners than MDM.
Using an EDM to remove
broken tooling is possible,
but it is time-consuming and
has limitations. The part has
to be small enough to fit in
the dielectric fluid container.
Also, an EDM machine will
take hours to extract a 3/8”
tap, where an MDM will take
just minutes.

4. EDM machines are
significantly more expensive
than MDMs and tying up an
expensive production machine
with tooling extraction could
be costly.
