기능

• About 3 times the drilling speed (our company ratio), ideal for drilling iron, stainless steel, etc.
• Drilling iron, stainless steel, aluminum, wood and resin.
• Cutting resistance has been reduced due to the unique cutting edge shape (sizes below 3.8 mm are usually cutting edges).
• The drilling speed is 3 times faster (compared to the manufacturer) because the cutting is done in 2 places, the center and the outer periphery.
• Hard to burr and close to a round hole.
• It is not susceptible to heat action caused by friction.
• Since the load on the drill is small, the battery can be reduced.
