If you need to bore larger holes in tough materials without stepping up to specialty tooling, the BECOLLO 3/4″ cobalt drill bit set is a practical, value-focused pick. Each bit is made from cobalt (5%) high speed steel to improve wear and heat resistance, helping extend service life when working in demanding metals.

The 135° split point is designed to self-center quickly to reduce walking and skating on the workpiece surface, while the 1/2″ reduced shank with 3 flats provides a more secure grip in your chuck—especially helpful on higher-torque drilling tasks.

  • Made from cobalt (5%) high speed steel for increased wear and heat resistance
  • 135° split point for faster starts and improved self-centering to help prevent walking
  • 1/2″ reduced shank with 3 flats for a more secure hold in the chuck
  • Suitable for hard metals such as stainless steel and cast iron (and also works on softer materials)
  • Includes 2 pieces of 3/4″ drill bits packed in a plastic case for storage and carrying

What you get: two uncoated, spiral-flute, 3/4″ (19.05 mm) jobber drill bits in a storage case—ready to keep on hand for fabrication, repair, or shop projects where a large diameter bit is required.
