Remember to account for any additional length needed to accommodate fittings or connectors. It’s always a good idea to measure twice and cut once to avoid any mistakes.

Once you have measured and marked the desired length, you are ready to move on to securing the conduit for cutting.

Step 2: Securing the Conduit

Before you start cutting the EMT conduit pipe, it’s important to secure it properly to ensure stability and accuracy. Here’s how to do it:

1. Prepare Your Workspace – clear a flat and stable surface to work on. Make sure there is enough space to maneuver the conduit.
2. Position the Conduit – place the marked section of the conduit on the workspace. Ensure that it is aligned straight and in the desired cutting position.
3. Use Conduit Clamps or Vise – to securely hold the conduit in place, use conduit clamps or a vise. Position the clamps or vise close to the cutting mark, ensuring a firm grip on the conduit.
4. Tighten the Clamps or Vise – tighten the clamps or vise to firmly secure the conduit. This will prevent it from shifting or moving during the cutting process.

By properly securing the conduit, you will have better control and stability when making the cuts. This will result in more accurate and precise cuts.

Now that the conduit is securely in place, it’s time to move on to the next step: cutting the conduit.

Step 3: Cutting the Conduit

Now that the EMT conduit pipe is properly secured, it’s time to make the cuts. There are different tools you can use for cutting EMT conduit, such as a conduit cutter or a hacksaw. Here’s how to cut the conduit:

1. Using a Conduit Cutter:
   1. Position the Cutter – place the cutting wheel of the conduit cutter against the marked cutting point on the conduit.
   2. Apply Pressure – firmly apply pressure on the conduit cutter and rotate it around the conduit. Continue rotating the cutter until you have made a complete cut through the conduit.
2. Using a Hacksaw:
   1. Align the Blade – position the hacksaw blade on the marked cutting point, ensuring that it is perpendicular to the conduit.
   2. Start Cutting – slowly and steadily cut through the conduit using back-and-forth sawing motions. Apply gentle pressure and take your time to maintain control and accuracy.

Choose the cutting method that you are most comfortable with and that suits the tools you have available. Remember to let the tool do the work and avoid applying excessive force, which can lead to uneven cuts or damage to the conduit.

Once you have made the cut, you can proceed to the next step: deburring the edges.

When cutting EMT conduit pipe, always use a specialized tubing cutter designed for metal conduit. This will ensure clean, precise cuts and help prevent damage to the pipe.
