The Makita D-46442 Step Drill Bit features a diameter range of 4 mm to 20 mm with a 1/4" hex shank designed for use with 1/4" bit holders. Overall length is 75 mm with a working length of 53 mm. The titanium nitride (TiN) coating enhances durability and cutting performance, while the stepped design allows multiple hole sizes to be drilled with a single bit, reducing the need for bit changes. Suitable for plastic, non-ferrous metals (copper, nickel, zinc), and sheet metal; also acceptable for alloy, steel, and cast iron.
