Bordo Drill Bit Reduced Shank 1/2" - 18mm - 2654-18.00

Features:

• 1/2" Reduced Shank Drill
• Reduced shank HSS twist drill.
• 118º notched point with 30º helix.
• Notched point is a variation on the standard chisel point, providing faster starting and reduced drill wander.
• 118º point angles are ideal for use in materials such as mild steel and cast iron.
• The 118º 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.
