Bordo 1/2" Reduced Shank Drill Bright/Black HSS - Metric
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.
Drill Bit Surface Treatment Bright/Black Finish
These 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 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.
