Description

Bordo 3/8" Reduced Shank Drill Bit Bright HSS - Metric

  • Reduced shank HSS twist drill.
  • 118° notched point with 30° helix.
  • 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

Drill Bit Surface Treatment Bright Finish

  • A bright finish tool has no surface treatment and is supplied in the as-ground condition.
  • These tools are suitable for general purpose use, particularly for non-ferrous applications.

Drill Bit Materials High Speed Steel (HSS)

  • Bordo HSS drills are ground from premium quality M2 high speed steel.
  • HSS can withstand higher operating temperatures than carbon steel without losing its temper (hardness).
  • This property allows HSS to cut faster than high carbon steel, hence the name high speed steel.
  • M2 HSS is an alloyed steel in the tungsten-molybdenum series which typically contains 4% Chromium, 5% Molybdenum, 6% Tungsten, 2% Vanadium and 1% Carbon(approx. by % wt).
  • The material is also subject to high temperature heat treatment to complete the process.
  • HSS has a very high wear resistance, a bending strength up to 4700MPa with high toughness and themoplasticity.
  • HSS drills are ideal for general purpose use in a wide variety of ferrous and non-ferrous metals, timber, and plastic.
