• High Speed Steel (HSS)
• No burrs, all-purpose type.
• Drilling a round hole without burring the back: There is a small diameter drill at the tip, and the circumferential blade performs end milling on the second stage, so even thin plate materials and plastic resin have a clean round hole without burring the back.
• Fast and Heavy Cutting: A new type of drill that combines a world-class center drill and an end mill for two-stage cutting enables cutting twice as fast as feed speed, resulting in higher efficiency.
• 3 times more durable: The tip drill has X-shaped cross thinning, and the two blades have a pure angle of more than the end mill.
