UNIKA UR21 Metal Wood SDS Shank Large Diameter (Ventilator, Air Conditioner, etc.)

[The two-blade blade enhances performance on metal siding such as galvalume steel sheets.]
The blade design is less likely to get caught on metal plates, making it easier to use on composite materials such as metal, insulation, and wood.
The special head design (patent pending) improves chip removal performance when cutting thick wood boards. It is less likely to burn and can be used for a wide range of purposes.
Complete set including center drill, body, and shank assembly.
The body can be easily replaced without tools, and can be easily attached and detached with one touch.
The shank is common, so by replacing the body and center drill, various types of holes can be drilled.
Galvanized steel sheet, wood / plywood, thin steel sheet / aluminum (2mm), metal siding board, 2x4 (nails can also be cut), PVC board / FRP, stainless steel plate (1mm), ceramic siding board, ALC board, gypsum board
