FAQ

Q1: How thick can this sheet metal cutter cut? Can it handle different materials?

A1: Cutting capacity varies by size and material:

10": Cold-rolled steel 0.78mm / Stainless steel 0.45mm

12": Cold-rolled steel 0.91mm / Stainless steel 0.63mm

14": Cold-rolled steel 1.20mm / Stainless steel 0.70mm

It can cut various metal sheets including cold-rolled steel, stainless steel, galvanized steel, tinplate, aluminum and copper. Do not exceed rated thickness to avoid damaging the blade.

Q2: What's the difference between 55# steel and ordinary carbon steel tin snips?

A2: The main differences are hardness and durability:

55# steel: A high-quality carbon structural steel with moderate carbon content. After quenching, it has high hardness, good toughness, good wear resistance and long service life

Ordinary carbon steel: Lower price, but insufficient hardness, prone to wear, blade dulls quickly, requires frequent replacement

Bunker selects 55# steel with special quenching treatment — cutting performance and durability far exceed ordinary tin snips.

Q3: How to choose among the three sizes? Which one should I buy?

A3: Choose based on the sheet thickness you commonly work with:

10" : Suitable for thin sheets and fine work, such as tinplate, thin aluminum, stainless steel under 0.5mm

12" : Medium size, balancing flexibility and cutting force — most commonly used for daily sheet metal work

14" : Suitable for thicker sheets, such as ~1mm cold-rolled steel, ~0.6mm stainless steel

If you frequently work with different thicknesses, a set of all 3 is recommended for higher efficiency.

Q4: Can the blade be sharpened when dull? How to maintain it?

A4: Yes, it can be sharpened. Use a sharpening stone or diamond file following the original blade angle — maintain the original edge angle, do not grind a reverse edge. Maintenance tips: ① Wipe off metal shavings and oil from the blade after use, apply anti-rust oil; ② Avoid cutting over-thickness sheets and hard materials; ③ Store in a dry place to prevent rust; ④ Apply anti-rust oil and put on a protective cover when not in use.

Q5: Do you offer OEM private label? What's the MOQ?

A5: Yes. OEM private label customization is supported, including brand logo, handle color and packaging design. MOQ for standard models starts from 36pcs per carton. Custom model MOQ depends on specific requirements. Welcome to contact us for detailed quotations and samples.
