BORDO 8pc Reduced Shank Metric Drill Set

• 118° notched point 30° helix.
• 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.
