Can your Drill Bits take HEAT? #powertools #tools #diy

What happens here

This video showcases the exceptional durability and heat resistance of Millner-Haufen Tool Co. cobalt drill bits by demonstrating their ability to drill through various tough materials like wood (to illustrate heat generation), hardened steel (a hammer), cast iron (a brake rotor), stainless steel, and ceramic tile. The demonstration emphasizes the bits' performance even without coolant in some instances, highlighting their robust design for challenging drilling tasks.
