Diablo’s premium Steel Demon 7 in. x 38 Tooth 20 mm Arbor Carbide Ferrous Metal Saw Blade has teeth made of Ti-Co high density carbide with titanium for a design that withstands impact, reduces wear, and lasts longer that standard carbide in metal cutting applications. Tri-metal shock resistant brazing allows metal cutting carbide tips to withstand extreme impact for maximum durability. Non-stick Perma-Shield coating protects the blade from heat and corrosion, reduces friction and pitch buildup. Laser-cut stabilizer vents absorb noise and reduce vibration for a cleaner cut and longer life.
