Worth the extra $ for the bi-metal, cuts smooth and straight through stock for days and holds up great even without any lube/coolant. Using on old delta horizontal saw.
Cuts everything I need it to.
Cut 3" steel square tubing x 1/4" thick walls and some 1" dia. alum. Did a very good job of both.
Dont waste your money on the cheaper carbon steel blades. Although bimetal blades cost more they last 3 times longer.
good quality blade made in the USA at a decent price
