This is a 6-piece set of HSS titanium-coated step and saw drill bits in a red plastic case.
The bits are made of high-speed steel (HSS) with a titanium coating for durability and corrosion resistance.
The set includes three step drill bits (sometimes called pagoda bits) and three serrated saw drill bits.
Step drill bits are designed to drill multiple hole sizes in thin materials like sheet metal, wood, and plastic.
The saw bits are used for cutting, drilling, and reaming, and their serrated edges help remove cutting waste efficiently.
The bits feature a triangular shank to prevent slippage in the drill chuck.
