"Been using Bad Dog bits for over 10 years, great product!"

Bad Dog Multipurpose Bits Are The Most Versatile Bits You Can Own!

Bad Dog Bits’ unique tip design creates a filing action to burrow through hard materials like tempered and high-speed steel and still drill soft materials like aluminum and PVC without ripping them apart. The Carbaloid tips resist fracture and stay sharper, longer than conventional bits. They’re SO DURABLE that they’re GUARANTEED FOR LIFE! Drill any combination of materials with the Bad Dog Multi-Purpose Drill Bits. Modify drilling speed to the recommended drilling speed of the material in each layer. Note: DO NOT USE AN AIR DRILL!
