These polygonal blades are primarily used on electrically powered rotary tools operating at up to 12,000 RPM. The unique 10-sided geometry prevents material drag and wire leakage when rolling or shearing through tough industrial fabrics.

Technical Specifications Overview

Blade Model	Outer Diameter (Knife Height)	Blade Thickness	Cutting Angle	Max Cutting Depth	Common Applications
BW50B	25.00 mm	0.60 mm	36°	3.5 mm – 5.0 mm	Standard synthetic textiles, canvas, light fiberglass.
BW51B	25.00 mm	0.60 mm	36°	5.0 mm	Intricate rotary contour cutting of technical fabrics.
BW52B	32.00 mm	0.60 mm	36°	7.0 mm	Thick materials, heavy felts, aramid, and multi-layer composites.

Note: All three models typically feature a standard 8.00 mm center mounting hole (aperture) to lock securely onto the tool arbor.

Material Composition & "Titanium" Coating

Base Core: These blades are manufactured from high-purity solid cemented tungsten carbide . Pure titanium is too soft to maintain a sustainable cutting edge for raw industrial cutting, so the core remains tungsten carbide to ensure rigid structural integrity.
The Coating: The "Titanium" designation refers to a high-performance Titanium Nitride (TiN) hard coat vapor-deposited onto the carbide surface. This golden/bronze coating reduces friction, dissipates heat buildup during high-RPM operations, and extends the overall blade lifespan by up to 3 to 5 times compared to uncoated options.
