Features Cemented Carbide Material: CNC milling extension rod is forged with cemented carbide, hardened and hard to be deformed. High Concentricity: CNC milling extension bar can be used for powerful milling to improve efficiency, with finely ground bore, high concentricity and high stability. Strong Clamping Force: CNC milling extension rod is highly rigid with strong clamping force, so you can have a safe using process. Cooperate with Machining: CNC milling extension bar can bring the milling cutter (not included) into the deep hole machining groove for machining. Widely Used: CNC milling extending rod is widely used in CNC lathe, machining center, tapping machine, drilling machine, milling machine and other equipment operations.
