Also called side Cutting Drill Bits, high speed steel saw drill bits with a titanium nitride (TiN) coating combine HSS strength with a wear resistant, low friction surface for longer life and smoother performance. Unlike regular drill bits that only cut straight down, each saw drill bit features sharp serrated edges for powerful side cutting, allowing you to drill, then cut horizontally to groove, enlarge, or shape openings. Ideal for woodworking, plastic, and light metal applications, including thin wood, plywood, MDF, aluminum, and thin iron sheet. Whether for DIY, woodworking, or light metalworking projects, these saw drills deliver fast, clean results with less effort.
