2651-5/8, 5/8″, Reduced 1/2″ Shank Drill

Description

About this item:

• 5/8″ Reduced 1/2″ 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.
