Features:Scope of applicationThis flat drill bit is compatible with handmade electric drills and battery drill bits. The torque of the 12V cordless drill is too low, so it is not recommended to use it. A 24V or 48V lithium drill is suitable. DurabilityThis flat drill bit for wood drilling is made of high-quality carbon steel material, which has high hardness and good durability. Anti-slip GrooveThis woodworking flat drill bit adopts a unique groove design, which can prevent the drill bit from slipping.
