Understanding the sizes

Drill bits are sized by the diameter of the hole they produce. HSS suits general metal and timber; cobalt HSS adds heat resistance for stainless and hardened steel; masonry bits carry a brazed tip for brick and concrete.

Working with drill bit set

Let the cutting edge do the work: steady pressure, moderate speed, and cutting fluid on metal. Too fast and dry is what blues a bit and destroys its temper. Pilot larger holes in steel with a smaller drill first.

What it is for

Metalwork, fabrication, vehicle repair, joinery and general maintenance drilling.
