BORDO Reduced Shank HSS 3/8″ Shank Fractional
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.
