Miller ACS-2 armored cable slitter


The Miller ACS 2 tool is an armored cable slitter, designed to slit corrugated copper, steel or aluminum armor layer on fiber feeder, central tube, and stranded loose tube fiber optic cables, as well as other armored cables.

The ACS 2 cable slitter can also be used for mid-span or end slitting of the thin jacket on loose tube micro cable, typically used in an blown fiber application.

The ACS 2 tool is adjustable from 4 to 10 mm, or 0.15 to 0.39 inches, for smaller cable O.D. options.

To begin using the ACS 2, first determine the cable construction. Multi-fiber cable construction may have a strength member that is internal and adjacent to the fibers or external in adjacent to the armor and jacket.

Determining the cable construction may aid in preventing tool damage.

Once the cable construction is determined, set the blade. The ACS 2 will be shipped with the slitting blade retracted. The cutting blade depth setting can be made with a sample piece of cable as a guide.

The bottom thumb knob has a slotted setscrew that has 10 graduations and adjusts the blade height as it’s turned.

Each full turn of the adjusting knob amounts to about 1mm (0.040 inch) of blade depth adjust. In turn, each graduation is equal to 0.1mm (0.004 inch) of blade adjustment.

Avoid setting the blade too deep in order to protect underlying layers.

Once the blade has been set, the first longitudinal cut can be made by loosening the black thumb knob completely, and rotating the blade assembly to the longitudinal position.

Next, place the cable in the tool opening, and adjust the roller with the yellow thumb knob for a snug fit.

Then, tighten the black thumb knob down, position the blade for a longitudinal cut. Pull the tool down the length of the cable to be stripped, with the blade set properly, the tool will often create a zipper sound on armored cables.

If you are working on an external strength member cable, the tool will follow the harden strength members and slightly spiral down the cable, allow the tool to follow the strength member.

Make a ring cut by first retracting the blade assembly, then index the blade assembly to the ring cut position, re-position the blade assembly to the cutting depth, and turn the tool two or three revolutions for a ring cut, stop the tool 180° from the first longitudinal cut, index the blade assembly back to longitudinal, and proceed to make the second longitudinal cut back to the start point.

At the end of this cut, made a second ring cut in the same manner as the first.

Using long nosed pliers, carefully peel back the jacket and armor to access the fiber.
