We had to cut in a couple of boxes in cement board today. Normally we use the oscillating saw to cut in for rework single gang device boxes 1104L’s. All it’d do yesterday with a wood blade was make sparks. We found this blade yesterday and it cut this morning like butter. Super impressed

I usually use the Bosch blade that is rated for ceramic tile.
regardless, carbide teeth on blades is a must

I only use carbide. Last week I cut through stainless steel sheet with it (not ideal but it works).
