These are cutting comparisons, not a complete refrigerant-tube preparation kit. Nominal plumbing sizes and actual outside diameter can differ.
HOW TO CHOOSE
What matters for the work
Use actual outside diameter
Match the cutter capacity and wheel to the material and actual tube OD. Do not assume a nominal pipe size equals the refrigerant tube measurement.
Check rotation clearance
A larger cutter or powered tool may not fit even when the tube is within its capacity.
Plan the preparation that follows
The required deburring, cleanliness, joining method and inspection depend on the installed system. A cutter is not the whole process.

RIDGID
101 Close Quarters Tubing Cutter (40617)
Best for: Copper service repairs where the space around the tube is limited.
The 101 is a compact manually fed tubing cutter. Its small body is the point of the recommendation: it gives a service kit a cutter for locations where a larger handle or powered head is difficult to rotate.
Start here for occasional supported copper cuts in restricted space. Check the actual outside diameter, available rotation and correct wheel. It does not remove the preparation required after cutting; compare 118 if you specifically want AUTOFEED in this close-quarters family.

RIDGID
118 AUTOFEED Close Quarters Tubing Cutter (86127)
Best for: Buyers who want AUTOFEED in a small tubing-cutter format.
The 118 adds RIDGID’s AUTOFEED feature to a close-quarters cutting role. It is worth comparing with the 101 for the feed mechanism, rather than assuming the shared compact appearance means the tools work identically.
Choose it if the feed arrangement suits the repairs you do. Confirm catalog 86127 and the published material range. The separate ratchet-handle accessory should not be assumed included in every listing; check the kit contents before comparing complete purchase cost.

RIDGID
151 Quick-Acting Tubing Cutter (31632)
Best for: Accessible tubing runs needing a broader cutter range than the 101.
The 151 is a quick-acting tubing cutter with a larger working range than the compact 101. It belongs in an installation or van kit when access and diameter make the smaller service cutter unsuitable.
Choose by tube size and clearance, not because a larger cutter looks more professional. Verify the wheel supplied with the exact model and the intended material; RIDGID also sells related cutters for different applications. Keep a compact cutter for spaces where the 151 cannot swing.

2471-20 M12 Copper Tubing Cutter
Best for: M12 users making repeated cuts in supported copper tubing.
The M12 2471-20 is a battery-powered copper tubing cutter. It moves repeated supported cuts into a powered workflow, but its head still needs the right diameter and access around the pipe.
Buy it because the volume of suitable copper cuts justifies the tool and battery. The tool-only listing is not a complete battery kit. Compare head clearance against a manual 101 before relying on it as your only service cutter, and follow the copper-specific instructions.

KNIPEX
90 31 02 TubiX Pipe Cutter
Best for: Users comparing a quick-positioning cutter with conventional screw-fed models.
TubiX 90 31 02 is KNIPEX’s adjustable pipe-cutter format with a quick-positioning mechanism. Its broader body and adjustment design put it closer to an installation cutter than a tiny emergency cutter.
Compare the supported outside diameters, wheel and body clearance with the 151. A faster positioning mechanism is useful only when the tool can reach and turn at the cut. Check the exact TubiX suffix and included deburring components; the family includes other sizes.
