Although this will slightly increase the overall cost of your project, it will be able to quickly cut through the tough metal casing on the shielded cable and will reduce the time required to install the cable.
No: use a saw to cut the shielded cable
Many people choose to use a hacksaw or other cutting tool to cut the shielded cable.
While this is possible, I strongly recommended that you do not attempt it.
When shielded cable is cut with a hacksaw or other cutting tool, it can produce rough or jagged edges that could damage the insulation of the shielded cable or even cut electrical wires inside the metal jacket.
Notched cables within shielded cable create a dangerous fire hazard. Check out the first tip in this article and understand a shielded cable cutter.
Do: I always use anti-chaff bushings
Anti-short bushings are plastic funnel-type elements that are inserted at the end of the shielded cable.
The rounded edges of the anti-short bushings help prevent nicks and cuts to the electrical cable within the sheathing and also help to better insulate the wiring to avoid arcing or short circuits.
