5D Coolant Through Carbide Drill
Coolant through drill, also known as solid alloy internal coolant drill, is a machining tool with 1 to 2 through holes or double spiral holes from the shank to the cutting edge, allowing compressed air, oil or cutting fluid to pass through. It cools the tool and workpiece and washes away chips, which is especially suitable for deep hole processing. Internal cooling drill bit can greatly improve cutting efficiency.
