Code:4AR40
Barcode:6002919133651
  • The HSS Black bit is a good all-rounder when it comes to drilling steel.
  • The black oxide coating provides heat resistance and lubricity as well as corrosion resistance.
  • The 118 degrees cutting point makes it a general purpose bit for drilling into wood, plastics, and milder steel types.
  • Not ideal to be used on stainless steel or harder metal types.

Ideal for soft metals like normal steel, copper and aluminium.

  • 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.
  • Can be used to drill into wood and plastics.
  • To prevent choking caused by sawdust, use a pumping action to keep removing sawdust from the hole being drilled.
  • Excessive heat caused by loose particles will damage the metal drill.
