기능

• Low price and high performance.
• The unequal pitch blade type enables smooth drilling.
• Long life with outstanding sharpness and cut.
• Dedicated chip discharge spring prevents debris from being caught.
• Significantly improves workability.
• When the spring is removed, deep drilling of wood, resin, etc. up to 23.5 mm effective length is possible.
• One-touch detachment for charging tools. (Electric drill can also be used)
• Blade edge uses cobalt high-speed steel (M42) with excellent heat resistance and durability, and achieves high performance with a high-precision finish.
• For drilling a wide range of materials such as thin steel plate (3.2 mm or less), stainless steel plate (1.6 mm or less), aluminum plate, wood, resin plate, FRP, metal-based siding, gypsum board, artificial marble, etc.
• Do not use a cordless impact driver for stainless steel plates only.
• The hole saw generates sparks during use.
• Do not use in places where there is a risk of fire or explosion.
• Be sure to wear protective equipment such as dust glasses, safety shoes, dust masks and earrings.
• Use the model for ironwork (rotation only) referring to the appropriate number of revolutions indicated in the instruction manual.
