About this item:
  • 23.5mm 1/2" Reduced Shank Drill
  • Reduced shank HSS twist drill.
  • 118° notched point with 30° helix.
  • Notched point is a variation on the standard chisel point, providing faster starting and reduced drill wander.
  • 118° point angles are ideal for use in materials such as mild steel and cast iron.
  • The 118° point creates easily controlled chips which are wide and thin.
  • Bordo reduced shank HSS drills are ground and then a black finish is achieved by steam tempering, a thermal process resulting in a porous tool coating.
  • This surface aids chip flow and heat dissipation.
  • The drill is then ground a second time to achieve a bright finish on the shank and cutting edges.
