Product Expert Notes
Keep a 5-pack in your tool bag so you can flip to the second point or swap blades when cutting reveals on acoustical ceiling tiles—a sharp blade is the difference between a clean shadowline and a ragged edge. These square-hole blades are a direct fit for the TP05110 Shadowline Cutter. Use light, consistent pressure and replace the blade at the first sign of tearing the tile facing.
Utility blades are extremely sharp—handle with care, wear cut-resistant gloves when changing blades, and dispose of used blades in an approved blade container.
