Versatile Applications: Excellent choice for drilling hard metals, including stainless steel, cast iron, and titanium alloys; also suitable for softer materials like wood and duroplasts. Comprehensive Size Range: Includes 29 sizes from 1/16″ to 1/2″ for all your drilling needs, ensuring you have the right bit for any project. Convenient Organization: Features an indexed drill bit holder for easy identification and a portable metal case for secure storage and transport.
