Fitur

• Clean working environment is achieved by absorbing dust generated when perforating concrete etc.
• Dust is absorbed not only in downward and sideways drilling, but also in upward drilling, reducing the burden on workers.
• The adapter and the bit can be easily removed when replacing the bit because of the round screw tightening.
• The blade diameter of 25 mm (5 blades) and 28 mm (6 blades) is strong against breakage and durable thanks to its integrated structure.
