NAP Gladu's new SuperSilent saw blades have reduced noise levels by 20 decibels. 

It's not a reason to take off your hearing protectors, but it may make you feel a little better if you weren't sure they were working before. The blades are 70% quieter then average saw blades.

NAP Gladu says the blades make scalpel-like cuts on solid wood and all types of panel: chipboard, MDF, plywood, and even abrasive materials such as laminate than can make for really noisy cutting.

Why are they quiet? It's how the blade is formed, and for that, NAP Gladu came up with some worthy branding: "MicroGeo polycrystalline" diamond teeth, which cut through solid woods and laminated core products with a 2mm ultra-thin kerf; and "Direct Chip Guide geometry" to for uninterrupted cutting in both rip and crosscut.

Another nice thing about this blade design is that it tends to direct debris away from the cutting path so you can see the line you are cutting.

While the blades were designed to slice through wood while keeping noise levels down, NAP Gladu says the same features also extend its life on the saw. 

“The Super Silent blades last up to six times longer than other blades," says Brett Reid, NAP Gladu's national sales manager, which "reduces the need for time-consuming tool changes."
