  • Cobalt drill bits are stronger and harder than Titanium bits but are more brittle and should be handled with care.
  • Cobalt can drill at much higher temperatures while maintaining sharpness.
  • Can be used to drill stainless steel.
  • The 135-degree angle of the cutting point is ideal for drilling thicker/harder steel.
  • The split point prevents the drill from wandering or running off the starting point.
  • Drilling into metal is much harder than drilling into wood or masonry.
  • Keep the revolutions per minute low and lubricate the tip of the drill bit to minimize heat.
  • This technique keeps your drill bits functioning at peak performance for longer.
  • The drill bit cuts the metal away. Due to this, the edges mustn't be blunted by excessive heat and friction.
