E533 machine taps for British Standard Whitworth threads are manufactured from High Speed steel to give you extended tool life and good performance and conform to the International Standards Organization. They are available with either a bright or a steam tempered finish, both of which will prevent workpiece material from sticking to the cutting edge of the tool, giving you the assurance of a clean, accurate hole.
