HEAVY DUTY TUBE CUTTERS

For tradies who want clean, square cuts without the muck-around.

Mastercool’s heavy-duty tube cutters (models 70033, 70035 and 70037) give HVAC & refrigeration techs fast, accurate cuts across copper, aluminium, brass and thin-wall stainless. Built tough, they’re a fair dinkum upgrade to the cheapies that slip and chew pipe.

Key Features & Trade Benefits

• Carbide steel cutting wheel — bites cleanly into copper and thin-wall stainless for square, repeatable cuts that reduce rework.
• Flare cut-off roller grooves — salvage more tube for re-flaring and avoid extra joins on service calls.
• Triple-chrome plated body — corrosion resistance for coastal and plantroom work; lasts longer in Aussie conditions.
• Retractable reamer + spare wheel (70033/70035) — deburr on the spot and keep cutting if a wheel chips.
• Sliding ratchet drive (70037) — easy cutting on large diameters in tight plantrooms without over-torquing your wrist.
• Size coverage from 1/8″ to 2-5/8″ O.D. — pick the cutter that matches the job and get it done first time.

Why This Product Matters

Real-world scenario: you’re up on a roof in 40-degree heat cutting 1-5/8″ suction on a split — last thing you need is a wobbly wheel and a burred edge. These Mastercool cutters track straight, bite fast and leave you with a clean face for a leak-free flare. Too easy. If you’re building out your kit, you can also browse our tube cutters category for alternatives.

Pro Tip

Score the tube light and even for the first two turns, then tighten a fraction each rotation — you’ll keep the cut square and extend wheel life. Add a dab of cutting fluid on stainless. She’ll be right.
