I’m also a chain maker & here’s 2 procedures I use for cutting
coils into rings. I use the Koil Kutter for cutting all my coils.
The Koil Kutter can be used with a Dremel (or equal), Ryobi or
Foredom #30 (or equal) hand piece. It can cut coils from about 3
mm to 30 mm diameter made from 10 to 32 ga wire. The coils can
be up to 3 1/2 in. long. I use 2 different procedures depending
on the gauge of the wire being cut. I wind my coils on a set of
steel mandrels varying in size from 2 - 13 mm in 1/2 mm steps.
Coils larger than 13 mm are wound on mandrels made for the
respective job, usually from PVC pipe.
The 1st procedure is used for heavier gauges (aprox 20 ga or
heavier). Both these procedures assume the tool is assembled &
Place the coil in the groove of the cutter base.
Apply a light coating of lubricant to the top of the coil.
Oil of wintergreen works well. Moisten the tip of a finger with
the lubricant & draw it along the top of the coil. Liquid
dishwashing detergent will also work.
Place the slotted cover over the coil.
Insert the screw in the end of the cover that has the stop.
Tighten the screw until it just contacts the top of the slotted
Insert the screw in the other end. Tighten the screw until it
just contacts the top of the slotted cover.
Use a popsicle stick or other thin tool to push the coil
toward the stop until it just touches the stop.
Tighten each of the 2 screws an additional 1/4 to 1/2 turn.
Note: If the top cover is tightened down too much, it will cause
the coil to be flattened a bit & pinch the saw blade (similar to
disc brakes) resulting in excessive heating.
Place the cutter over the coil & cut. Be sure the shield is
installed correctly. The saw blade should be centered in the slot
of the top cover.
For coils made of lighter gauge wire (22 ga & smaller) the
following procedure works well for me.
Cut 2 lengths of masking tape a little longer than the length
of the coil to be wound. Place them so they can reached
conveniently after the coil is wound.
Wind the coil as usual.
Unwind the coil 1/2 to 1 turn will make it easier to remove
from the mandrel. Before cutting the coil from the wire supply,
cover the coil completely with the 2 pieces of masking tape. I
put the tape on the coil the long way as opposed to round &
Cut the coil from the wire supply & remove it from the
Use the procedure above to cut the coil, OMIT the step that
lubricates the coil.
Remove the rings from the masking tape.
Here’s another way to cut coils made of thinner gauge wire.
Wind the coil on a suitably sized wood mandrel.
Tape the finish end of the coil in place with masking tape
before cutting the coil from the wire supply. Leave the coil on
Place the coil, mandrel & all in the cutter coil holder.
Cut the coil as in procedure 1 above.
If there are little burrs left on the ends or the rings cut from
the coils, the saw blade may be dull & need to be replaced.
If there any other questions, ask away, I’ll help if I can.
