This twist drill bit from RS PRO is an excellent all-round tool for general industrial drilling applications. It's manufactured to DIN 345 standards, so it's suitable for use on a wide variety of materials, including steel and cast iron.
This tough drill bit has a morse taper shank, which has widely been adopted as the standard mount for drills. This means it will be compatible with your existing equipment.
The drill bit is made of high-speed steel (HSS). This material has a high level of resistance to friction and corrosion, making this bit ideal for heavy, continuous use, as it won't get damaged or blunted from drilling. It's also highly resistant to heat, so you can safely use it on wood or plastic materials without burning or melting them.
