Permaswage® Chipless Cutters (Tube Cutters): Complete Part Number Guide
Proper tube cutting is one of the most important steps in preparing tubing for a successful Permaswage® installation. Before a fitting can be swaged onto a tube, the tube must be cut cleanly, squarely, and with minimal deformation.
Permaswage® chipless cutters, also commonly referred to as Permaswage® tube cutters, are designed to help technicians prepare tubing for aerospace and high-pressure fluid system applications. These cutters help create a clean tube end before deburring, marking, fitting installation, and final swaging.
In this guide, we'll explain what Permaswage® chipless cutters are, how they are used, and provide a complete part number chart for the tube cutters and replacement cutter wheels.
What Is a Permaswage® Chipless Cutter?
A Permaswage® chipless cutter is a tube cutting tool used to cut aircraft and aerospace tubing without producing excessive chips, debris, or rough edges. In official tooling references, these tools may also be listed as tube cutters.
The purpose of the cutter is to create a clean, controlled cut before the tube is deburred and prepared for fitting installation. A proper cut helps ensure that the tube can be inserted correctly into the fitting and that the swage operation can be performed consistently.
Unlike abrasive cutoff wheels, saws, or general-purpose cutting tools, Permaswage® chipless cutters are intended for controlled tube preparation where cleanliness, accuracy, and repeatability are important.
Why Use a Chipless Tube Cutter?
Using the correct tube cutter is critical because poor cutting can cause problems later in the installation process.
A clean tube cut helps:
- Reduce tube deformation
- Minimize loose chips and metal debris
- Improve fitting insertion
- Support proper deburring
- Improve swage consistency
- Reduce the risk of contamination in fluid systems
- Prepare the tube for accurate insertion depth marking
In aerospace hydraulic, pneumatic, fuel, and lubrication systems, tube preparation quality directly impacts the reliability of the finished connection.
How Permaswage® Tube Cutters Are Used
The tube cutting process is typically performed before deburring and before the insertion depth is marked on the tube.
- Mark the cutting point on the tube.
- Open the tube cutter and position it over the tubing.
- Advance the cutter wheel until it contacts the tube.
- Rotate the cutter around the tube.
- Gradually advance the cutter wheel as needed.
- Continue rotating until the tube is fully cut.
- Inspect the tube end before deburring.
- Proceed with deburring and tube preparation.
Technicians should avoid over-tightening the cutter wheel because excessive force can deform the tube and negatively affect the fitting installation.
Permaswage® Chipless Cutter and Tube Cutter Part Numbers
The following table lists the standard Permaswage® tube cutter part numbers by tubing size range.
| Tube Size Range | Common Dash Sizes | Tube Cutter Part Number | Spare Cutter Wheel |
|---|---|---|---|
| 3/16" through 3/8" | -03, -04, -05, -06 | D12530-001 | D12530-109 |
| 1/2" through 3/4" | -08, -10, -12 | D12531-001 | D12531-109 |
| 7/8" through 1-1/2" | -14, -16, -20, -24 | D12532-001 | D12532-109 |
Replacement Cutter Wheel Part Numbers
Replacement cutter wheels are important because a dull or damaged cutter wheel can create poor tube cuts, increase deformation, and make tube preparation more difficult.
| Tube Cutter Part Number | Replacement Cutter Wheel | Tube Size Range |
|---|---|---|
| D12530-001 | D12530-109 | 3/16" through 3/8" |
| D12531-001 | D12531-109 | 1/2" through 3/4" |
| D12532-001 | D12532-109 | 7/8" through 1-1/2" |
When Should the Cutter Wheel Be Replaced?
The cutter wheel should be replaced whenever it becomes dull, damaged, chipped, or no longer cuts efficiently. A sharp cutter wheel helps produce a cleaner tube end and reduces the likelihood of tube deformation during cutting.
Signs that a cutter wheel may need replacement include:
- Difficulty cutting through tubing
- Rough or uneven tube ends
- Excessive force required to cut
- Visible damage to the cutter wheel
- Tube deformation during cutting
- Poor fit-up before deburring or swaging
Chipless Cutting vs. Standard Cutting Methods
In general maintenance environments, technicians may use saws, cutoff wheels, or other cutting tools to cut tubing. However, aerospace tube preparation requires greater control.
Permaswage® chipless cutters help reduce many issues associated with general cutting methods, including:
- Excessive metal chips
- Contaminated tubing
- Rough tube ends
- Angled cuts
- Tube wall deformation
- Additional cleanup time
For Permaswage® installations, the quality of the tube cut directly supports the next steps in the process: deburring, insertion depth marking, fitting placement, swaging, and inspection.
How Tube Cutting Fits Into the Permaswage® Installation Process
Tube cutting is only one step in the full Permaswage® installation process. After cutting, the tube must be deburred, cleaned, marked, fitted, swaged, and inspected.
A typical preparation sequence includes:
- Confirm tube size, material, and wall thickness.
- Cut the tube to the required length.
- Deburr the tube end.
- Clean the tube.
- Mark the insertion depth.
- Install the fitting.
- Swage the fitting.
- Inspect the completed swage.
Using the proper cutter helps ensure the rest of the process begins with a clean and properly prepared tube end.
