2. Safety Information
Always observe basic safety precautions when using hand tools to reduce the risk of personal injury. Failure to follow these instructions may result in serious injury.
- Wear Eye Protection: Always wear ANSI-approved safety glasses or goggles when operating this tool.
- Keep Work Area Clean: Cluttered work areas invite accidents.
- Use the Right Tool: Do not force the tool or attachment to do a job for which it was not designed.
- Inspect Tool Before Use: Check for damaged parts. Before using the tool, any part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function.
- Secure Workpiece: Ensure the tubing is securely held to prevent movement during cutting.
- Keep Hands Clear: Keep hands and fingers away from the cutting wheel during operation.
- Proper Grip: Maintain a firm grip on the tool.
- Deburr Edges: Cut edges of tubing can be sharp. Use appropriate deburring tools after cutting.
3. Product Features
The RIDGID 31803 65S Tubing Cutter incorporates several design elements for efficient and precise cutting:
- Bearing-Equipped Rollers: Features 12 individual bearings that replace traditional rollers, providing a smoother rotation and increased speed around the tube.
- Stainless Steel Cutter Wheel: A specially designed cutter wheel with bearings in its hub reduces drag, contributing to a smoother cut. The wheel is precision-machined from high-grade steel for durability and accuracy.
- Contoured Frame: The frame design allows for easy alignment of the tool on the tubing and facilitates cut adjustment.
- X-CEL Knob: A large, ergonomic X-CEL knob provides a firm grip, enabling quick and easy cutting.
- Cutting Capacity: Capable of cutting tubing from 1/4-inch to 2-5/8-inch (6 mm to 67 mm).

4. Setup
The RIDGID 31803 65S Tubing Cutter is ready for use out of the box. No assembly is required. Before first use, inspect the cutting wheel for any damage or debris.
- Inspect the Cutter: Ensure the cutting wheel and rollers are clean and free from obstructions.
- Prepare Tubing: Ensure the tubing to be cut is clean and free of burrs or deformities at the cutting point. Mark the desired cut location clearly.
5. Operating Instructions
Follow these steps for safe and effective tubing cutting:
- Open the Cutter: Rotate the X-CEL knob counter-clockwise to open the cutter jaws sufficiently to fit over the tubing.
- Position the Tubing: Place the tubing between the rollers and the cutting wheel. Align the cutting wheel with the marked cut line on the tubing. Ensure the tubing rests firmly on the rollers.
- Close the Cutter: Rotate the X-CEL knob clockwise until the cutting wheel makes light contact with the tubing. Do not overtighten initially.
- Begin Cutting: Rotate the cutter around the tubing, applying light pressure by turning the X-CEL knob clockwise approximately a quarter turn for each full rotation of the cutter.
- Continue Cutting: Maintain steady, even pressure and rotation. The bearing-equipped rollers and cutter wheel are designed to reduce friction and provide a smooth cut.
- Complete the Cut: Continue rotating and tightening until the tubing is completely severed.
- Remove and Deburr: Open the cutter and remove the cut tubing. Use a reamer or deburring tool to smooth the inside and outside edges of the cut tubing.

6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your RIDGID 31803 65S Tubing Cutter.
- Cleaning: After each use, wipe down the cutter with a clean cloth to remove any metal shavings or debris.
- Lubrication: Periodically apply a light machine oil to the moving parts, such as the screw mechanism and roller bearings, to ensure smooth operation.
- Cutter Wheel Replacement: The cutting wheel is a wear item and will eventually become dull. A dull wheel can cause uneven cuts or deform the tubing. To replace the cutter wheel, use replacement cutter wheel model E-635 (RIDGID Part Number 29973). Refer to the diagram in Figure 3 for the general assembly of the cutter wheel.
- Storage: Store the tool in a clean, dry place away from moisture and corrosive materials.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven or rough cut | Dull or damaged cutting wheel; Insufficient or uneven pressure; Tubing not properly seated. | Replace cutting wheel (E-635 / 29973); Apply consistent, light pressure; Ensure tubing is firmly on rollers. |
| Difficulty rotating cutter | Excessive pressure; Dirty or unlubricated screw mechanism/bearings; Damaged rollers. | Reduce pressure; Clean and lubricate screw and bearings; Inspect and replace damaged rollers if necessary. |
| Tubing deforms during cut | Dull cutting wheel; Too much pressure applied too quickly. | Replace cutting wheel; Apply lighter, more gradual pressure. |
