118° Point, Oxide Coated
• High Speed Steel (HSS) provides good wear resistance
and can be used in general purpose applications on
both ferrous and nonferrous materials.
• Oxide prevents chip building, galling and welding
on the workpiece. It is commonly used on low carbons,
stainless steel and iron based ferrous metals.
• Spiral flutes are constructed of a higher flute
angle to remove chips easier.
• 118° point for quick penetration.

135° Point
• Cobalt — provides better
wear resistance in hardness and
toughness compared to high speed steel (HSS)
• Use in high-tensile alloys, titanium, cast iron,
Inconel and high-nickel stainless steel.
• 135° Self-centering split point prevents "walking".
• Heavy-Duty core construction fives greater strength
and rigidity than conventional drills

118° Point, Oxide Coated
• High Speed Steel (HSS) provides good wear resistance
and can be used in general purpose applications on
both ferrous and nonferrous materials.
• Oxide prevents chip building, galling and welding
on the workpiece. It is commonly used on low carbons,
stainless steel and iron based ferrous metals.
• Spiral flutes are constructed of a higher flute
angle to remove chips easier.
• 118° point for quick penetration.

Fractional Cobalt
Screw Machine Drills
135° Point
• Cobalt — provides better
wear resistance in hardness and
toughness compared to high speed steel (HSS)
• Use in high-tensile alloys, titanium, cast iron,
Inconel and high-nickel stainless steel.
• 135° Self-centering split point prevents "walking".
• Heavy-Duty core construction fives greater strength
and rigidity than conventional drills
