Why choose it

The tungsten carbide teeth stay sharp longer than standard steel, reducing downtime and blade changes.

Expansion slots dissipate heat, keeping the blade flat and true even during extended use.

Good to know

The 30 mm bore fits most standard circular saws in the 185 mm class. Always check your saw's arbor size and maximum RPM rating before use. For best results, keep the blade clean and sharp, and store it in a dry place to prevent corrosion. One blade per pack.
