4mm Cobalt Drill Bit

The Kango 4mm Cobalt Drill Bit is designed for an improved drilling performance into stainless steel and hard metals while still being suitable for wood and plastic. Its M35 5% cobalt blend has been formulated to withstand extreme levels of abrasion and heat. 

The tip has four cutting chamfers that support maximum material contact, faster drill speeds, and cleaner holes. A 135° split point on the tip helps prevent this Drill Bit from wandering and provides more precision at the starting point. 

The tapered core design provides a thicker and stronger base that helps prevent bit breakages. Its rapid eject flute shape supports faster drilling speeds while ejecting chips and material.
