Starrett Improves Hole Saws


The L.S. Starrett Co. released an improved version of Deep Cut bi-metal hole saws with a distinct variable pitch tooth design that features a pattern of seven progressive teeth called NVP Tech (New Variable Pitch). This new tooth pattern, along with a special tooth set, delivers fast, aggressive cutting action. The saws are for cutting thicker material and feature a high-performance tooth material with extra cobalt for enhanced heat and wear resistance. The saws have a hole depth of 2 in. and are for cutting metal or tubes with a wall thickness of more than 1/8 in.
