Need a durable drilling tool that can handle industrial use and fit your existing equipment? Try this twist drill bit from RS PRO. It has a DIN 345 morse taper shank, so it's compatible with most industry-standard drills. This tough twist bit is made of high-speed steel (HSS), so it has the strength and durability to cut through extremely hard materials like stone and cast iron without blunting or breaking. It can stand up to heavy use over a long period of time without the risk of damage from abrasion or corrosion. The HSS material also provides excellent thermal resistance when exposed to continuous heat. That means you can safely use this drill bit on wood, plastic and other soft materials without burning or melting them.
