Martindale Electric U-Slot Undercutting Saw, MFR ID martindale_tun_u-slot

The tungsten carbide u-slot undercutting saws are carefully designed as to tooth form, hollow grind, hardness, etc. and are manufactured to close tolerances. While used primarily for undercutting mica and slotting risers of commutators, Martindale undercutting saws are also used for cutting steel, aluminum, plastics and other materials not requiring set teeth. - When u-slot carbide saws are used on other equipment than our undercutters, steel supporting washers are recommended to reduce breakage. Carbide saw blades are harder than high speed steel saws, therefore more brittle and should not be subjected to applications where shock may shorten the service life.
