Key Factors to Consider
When shopping for a fiberglass insulation cutter, here are some key factors to keep in mind:
Blade Type
Look for a cutter with a serrated or scalloped blade specifically made for fiberglass. The teeth on these specialty blades will grip and slice the glass fibers cleanly. Straight-edge razor blades or utility knife blades are not ideal since they will tear the material.
Blade Length
Longer blades around 8 to 10 inches make straight cuts easier across wider batts of insulation. Shorter 3 to 5 inch blades provide more control for detail work, curves, and angles.
Blade Material
High carbon steel blades stay sharper longer than stainless steel. Carbide tipped blades are even more durable and maintain their edge over repeated use.
Handle Design
Look for cushioned, ergonomic handles that will be comfortable to grip during prolonged use. Handles with finger guards protect your hands from accidental contact with the blade.
Safety Features
Retractable blades, blade locks, and blade storage covers are useful safety features to have on a fiberglass insulation cutter. This will help keep the sharp blades protected when not in use.
Accessories
Some cutters include helpful accessories like carrying pouches, measuring tapes, or built-in bubble levels. These can add convenience when working on insulation projects.
