kwb Lâminas de substituição para isolamentos, lâminas de corte, 18 mm, 5 unid. (024605)

These replacement blades are cut specifically for insulation work, with a precision-ground edge that slices cleanly through mineral wool, polystyrene and foam boards without tearing or binding. The 18 mm width fits any standard snap-off utility knife, and the seven-segment design lets you snap away dull tips for a fresh edge in seconds.

Highlights

• High carbon steel blade, 0.6 mm thick, holds its edge longer in abrasive insulation
• Seven snap-off segments per blade – always a sharp point ready
• Pack of 5 replacement blades, blister packed for safe storage
• Compatible with all standard 18 mm snap-off knives

In daily use

When you are cutting batts or rigid foam all day, a dull blade slows you down and leaves ragged edges. These blades are ground extremely sharp out of the pack and stay sharp through repeated cuts. When the tip finally dulls, snap it off and keep going – no need to swap blades mid-task.
