Power Trowel Blades

Power Trowel Blade Types and Machine Fitment

Power trowel blades include finish, combination, float, and polymer options for different machines and applications. Match blade dimensions, mounting style, bolt-hole count, and spacing before ordering. Machine diameter alone does not confirm fit. Check each product’s specific compatibility.

Standard, Ultra Blue, and Heavy-Duty Gold offer different steel thicknesses within corresponding blade designs. For example, the 8 × 14-inch SK101 combination blade is 0.074 inches thick, SK101B Blue is 0.082 inches, and SK101G Gold is 0.092 inches. Thicker steel is designed for longer wear and fewer blade changes.

Orange Thunder polymer blades provide non-marring finishing for decorative concrete and slabs intended for polishing. Standard SK100-OT and SK101-OT models are for walk-behind machines only. Their steel-backed SK100-OTSR and SK101-OTSR counterparts support compatible walk-behind and ride-on machines. These polymer blades are not for use with float pans.
