This router bit set proved very versatile for our team's needs. The tongue groove is adjustable which is a tremendous advantage when attempting different cuts. Industrial and Scientific quality is undeniable, the set is virtually indestructible. Using this product, our team found that we could focus on craftsmanship rather than worrying about equipment limitations. The one downside was that the bit is slightly bulkier than some other router bits, but it didn't hinder our ability to create quality products.
