Premium Materials: Twist drills are forged from high-quality materials, and the drill bits undergo quenching and heat treatment, resulting in high hardness and excellent wear resistance. We offer four sizes of twist drill bits: 14mm, 16mm, 18mm, and 20mm. Different sizes can meet your various needs. Large Eddy Current Design: This twist drill bit features a smooth, flat, enlarged chip flute and a high-temperature resistant, non-stick coated insert. High Durability: Due to the faster drilling speed, twist drills generate less heat, resulting in less wear. Wide Applications: Twist drills are suitable for electric drills and bench drills, and are widely used in home decoration, DIY crafts, and other scenarios. They are suitable for stainless steel, iron, copper, aluminum, and wood.
