RS PRO HSS Twist Drill Bit, 30mm Diameter, 296mm Overall

If you need a versatile tool that can stand up to heavy-duty drilling applications, choose this twist drill bit from RS PRO. Its morse taper shank is manufactured to current industry standards, so it will be compatible with your existing drills and equipment.
This tough twist bit is made from high-speed steel (HSS) and meets DIN 345 standards, meaning it's designed to cut through hard materials like concrete, stone and cast iron. Its durability means the drill bit can withstand heavy industrial use over a long product life without blunting or breaking.
The HSS material also provides excellent thermal resistance. This means the bit won't heat up due to friction, so you can safely use it on softer materials like wood and plastic without burning or melting them.
