Evolution Power Tools 180BLADETS Thin Steel Cutting Blade, 7-Inch x 68-Tooth, Blue

Fantastic, speedy cutting in metal roofing sheets. I only wish they made it in a smaller blade size that fitted my cordless saw. NOISY as hell though, and be careful with the hot chips liberated - eye and ear protection are MANDATORY not optional.

These blades are remarkable. When new they cut through 24ga steel siding like it is plywood. The cut edges are very smooth. No sparks and very little heating around the kerf. I was able to cut through 20 sheets of 2" square corrugated siding before the blade lost it's edge. Do not try to cut with a dull blade. Very different results.

What I was cutting: 2” 3/16 square tube, 1 1/2” 1/8” angle, 3” 3/16” C-channel. The first few cuts were very impressive, as someone said, “like butter”. However, after 15-20 cuts it was done.

Cuts smoothly threw metal I even tryed a 2x4

It cuts well but it does tend to bind when I cut.

The saw and blade combination is dynamite. I was able to cut 1/16" metal like butter. I cut over 100 feet of sheet metal with one blade and still going strong great product.

Great item - my 10th purchase

I have been using a cold cut saw for about 10 years and tried various blade brands and types for cutting thin wall (.050"- .250") hot rolled ,1025 and 4130 tubing. This one is the best that I have used.

Excellent

Muy bueno

Better than other brands like dewalt, and this is made in Japan

Quality made. But not durable enough. Works fine for a couple hours then lose cuts, as to be sharpen.

solo me duro un día. tal ves por que lo metí en una sierra que giraba el doble de las revoluciones recomendadas por el disco. no revise ese detalle y los todos los dientes salieron disparados.
