Spin Tools (SPIN) are drill-driven flaring and swaging tools designed to form tube ends quickly for HVAC/R installs and repairs. This collection brings together genuine SPIN flaring & swaging sets plus the tube-prep essentials that make the difference between “looks OK” and “pressure-tested confidence”: clean cuts, proper deburr, correct torque, and the right gear to finish commissioning.

Best for: mini-split and ductless line sets, refrigeration service work, and any job where you want repeatable joints without hauling a bench kit everywhere.

Shop by job (fast navigation)

• Flaring & swaging kits (traditional sets) for broad compatibility and bench work
• Tube cutters for clean, square cuts (no hacksaw burr drama)
• Deburring tools to clean the ID/OD before forming
• Torque wrenches for consistent flare nut tightening
• Tube expanders & heads for expansion work and fit-up
• Brazing / torch gear when the job calls for permanent joints

What are SPIN tools in HVAC/R?

“SPIN” tools are drill-driven flaring and swaging “bits” that form copper tube ends using a friction-heat method. The manufacturer positions this approach as a way to help preserve metal malleability during forming, reduce cracking, and speed up repeatable joints compared with many conventional clamp/yoke tools.

SPIN vs traditional flaring kits — which should you buy?

• Choose SPIN when you’re doing lots of splits/line sets and want speed + portability on the ladder or rooftop.
• Choose a traditional kit when you need maximum compatibility (odd sizes/angles), bench repeatability, or you’re matching existing fleet tools.
• Many techs run both: SPIN for daily install speed, traditional kit as the “covers everything” backup.

Quick pick: choose your SPIN set (common use cases)

Tip: Always check the specific tool requirements for drill speed/power and avoid impact/hammer modes for forming work.

The “no call-back” tube prep workflow

1. Cut square with a proper tube cutter (clean cut = cleaner forming).
2. Deburr ID/OD with a deburring tool (metal filings and ragged edges are leak starters).
3. Form the tube end (flare or swage) using the correct tool for the tube size/material.
4. Assemble correctly (keep sealing surfaces clean; use suitable lubricant where specified).
5. Tighten consistently using a torque wrench where possible (especially on repeated installs).
6. Pressure test and evacuate properly before releasing charge:
   • Regulators for controlled pressure testing setups
   • Vacuum pumps + vacuum gauges (micron gauges) for evacuation verification
   • Refrigerant hoses and refrigerant gauges for charging/commissioning
   • Vacuum pump oil for reliable pump performance
   • Recovery units when recovery is required

Trade notes: flare joints, torque and leak prevention

Flare joints aren’t “set and forget”. Good outcomes come from preparation, correct tooling, and tightening to specification. Where applicable, guidance in the AU/NZ refrigerant handling code of practice references:

• Keeping flare connections to a practical minimum in some system contexts
• Using annealed pipe and correct wall thickness for flaring
• Cutting with a pipe cutter and de-burring properly
• Using a suitable refrigerant-compatible lubricant on flare threads/sealing surfaces where specified
• Tightening using a torque wrench and not exceeding manufacturer instructions

Common torque ranges (always confirm OEM instructions)

For single-flare copper tube connections, typical torque ranges are commonly referenced by tube size (example ranges are shown in the AU/NZ guidance table). Always confirm your equipment manufacturer’s requirements for the specific unit and flare nut type.

AU compliance note (especially for R32 split systems)

For systems using flammable refrigerants, Australian standards guidance and industry commentary commonly emphasise where permanent joints are required in occupied spaces, with limited exceptions (for example, joints directly connecting to indoor units). If you’re unsure about what’s permitted on a specific install, follow the unit manufacturer instructions and use a licensed RAC technician.

Spin Tools FAQ (real questions we get from the field)

1) Do SPIN tools replace a standard flaring tool completely?

Not always. SPIN tools are great for fast repeatable work, while traditional kits can be better for edge cases, bench work, or broader compatibility. Many techs carry both.

2) Do I still need a cutter and deburrer?

Yes — forming tools work best after a clean square cut and proper deburr. Start with a tube cutter and deburring tools.

3) Can I use an impact driver?

Generally, no — avoid impact/hammer modes for tube forming. Use a suitable drill/screwdriver and follow the tool requirements for speed/power.

4) Why do flare joints leak even when the flare “looks good”?

Common causes include poor deburr, damaged sealing surfaces, misalignment, contamination, or over/under tightening. A torque wrench improves repeatability.

5) What else should I add to the cart to finish the job properly?

At minimum: pressure test setup and evacuation verification — see regulators, vacuum pumps, vacuum gauges, plus hoses and gauges.

6) Are these tools suitable for apprentices?

Yes — with supervision. They can help with consistency, but technique still matters (prep, alignment, torque, test/evacuation).

7) Can informed DIYers use these?

Tool use is one thing; refrigerant work is another. If the job involves refrigerant handling or could cause refrigerant to be emitted, engage an appropriately licensed professional.
