Hilmor 1885432 Replacement Utility Knife Blades

Tough bi-metal blades for clean, safe cuts

Keep your Hilmor knives cutting sharp all week. These Hilmor 1885432 bi-metal blades are shatter-resistant and purpose-built for HVAC techs who cut insulation, duct liner, carton and strapping on the daily. Designed as the genuine replacement for the 1885433 Folding and 1885434 Retractable knives—no mucking around with fitment.

Key Features & Trade Benefits

• Bi-metal construction — shatter-resistant edge for fewer breaks and safer cuts on site.
• Exact fit for Hilmor 1885433 & 1885434 — swap in, lock, and get back to work. No filing or shims.
• 5-pack value — reduce downtime; change blades when the cut starts to drag, not when it’s “too late”.
• Clean, precise cuts — helps avoid ragged insulation edges and rework. (Fair dinkum time-saver.)

Why this product matters

On a sweaty Brisbane rooftop, slicing duct wrap with a dull blade is a recipe for frayed edges and call-backs. Swap to a fresh 1885432 and it glides—neat cut, tape sticks first go, and you’re packed up sooner. Bloody good for productivity.

Pro Tip

Don’t pry with a utility blade—ever. If the cut starts tearing, flip to the fresh edge or swap the blade. Pair with cut-resistant gloves and bin used blades immediately—no worries.
