BB 150mm Length Coated Carbide Drill Machine Metal Hole Making Tool for Steel Stainless Steel(1.5~6.45mm) ball nose end mill The high-speed rotating BB Friction

The high-speed rotating BB Friction Drill contacts the surface of the workpiece and fricts with the metal surface to produce high temperature (600 degrees) or above

This effect is particularly significant when machining viscous materials (such as aluminum and stainless steel)

good heat and chip resistance
