Description
The Mastercool 70025 Capillary Tube Cutter is a compact, job-ready tool for refrigeration techs, apprentices, and service crews who need clean capillary cuts with zero crush. It’s quick, safe, and accurate—so you’re back on the tools faster, no worries.
Key features & trade benefits
- Cuts all cap tube sizes — One tool covers the lot, saving time on set-up and tool swaps.
- Won’t collapse the tube — Preserves internal diameter for uninterrupted refrigerant flow and fewer call-backs.
- Hardened steel construction — Long-lasting cutting edges built for daily trade abuse.
- Rubber-grip handles — Confident one-hand control when you’re up a ladder or in a tight back-of-cabinet space.
- Compact, pocket-friendly body — Slides into a pouch or toolbag; perfect for cramped jobs.
- Rugged black finish — A tough, trade-ready look that resists scuffs.
Why this product matters
Ever tried to trim a cap tube behind a display fridge only to crush it with the wrong cutter? Fair dinkum, that’s a mood-killer. The 70025’s jaw and cutting profile deliver a clean, crush-free cut so metering stays true and systems balance properly. That means fewer comebacks, smoother commissioning, and a happier client when you fire it up the first time. For more specialised cutters and hand tools, see our Hand Tools collection.
Pro tip
Mark the cut, don’t twist the tube after cutting, and lightly dress the edge if required. Keep the offcut clear of the line so nothing ends up in the filter-drier. She’ll be right.
Compatibility & system info
Designed for copper capillary tubes typically used across domestic refrigeration and light commercial HVAC systems (commonly seen with R134a, R600a, R290 and legacy systems). Purpose-built cutter prevents ovalising so capillary metering remains consistent.
Local jobsite context
Working rooftops in Perth during summer or in humid Brisbane plant rooms, you need quick, accurate cuts with a tool that won’t slip. This little ripper gives you clean results without fuss.

FAQs
- Will it crush soft capillary tube?
- No. The cutter is designed to cut without collapsing the tube, keeping the internal bore intact for flow accuracy.
Is it only for copper?
It’s made for capillary tubes commonly used in refrigeration work (typically copper). For larger copper/aluminium tubing, consider the Mastercool MINI Tube Cutters.
Do I need a deburrer afterwards?
Cap tubes usually cut clean, but if you feel a slight lip, dress it lightly so nothing ends up in the system. Pair with a quality flaring or swaging tool when rebuilding circuits, e.g. Mastercool 70053 Flaring & Swaging Set.
What if I need to cut stainless or thicker wall tube?
That’s outside a capillary cutter’s scope. Use a dedicated tube cutter like the Imperial TC1010SP for 1/8"–5/8" stainless.
