RS PRO HSS Step Drill Bit 8 mm x 20 mm


Need to drill holes of different sizes? Choose this step drill bit from the RS PRO range. It's a versatile choice for workshops where you need to drill a range of hole sizes for different projects.


The bit is made of HSS (high-speed steel) for durability and resistance to heat, making it suitable for use at high temperatures. Its seven distinct steps mean you can easily drill a range of hole sizes between 8 mm and 20 mm.


It has exceptional non-slip features if held in three-jaw chucks, making it safe to use. It also meets the American (ANSI/ESD S20.20:2014) and European (BS EN 61340-5-1:2007) ESD (electrostatic discharge) standards, minimising the risk of electrostatic discharge.
