135° Split 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
• #1 to #60 sold in packs of 12

HSS 118° • Cobalt HD 135°
• These drills are recommended
for ferrous metals (steel/iron).
• They have a surface treatment that
reduces the amount of chip welding,
increases abrasion resistance and
improves the chip flow.
• Sold individually.

HSS 118° • Cobalt HD 135°
• These drills are recommended
for ferrous metals (steel/iron).
• They have a surface treatment that
reduces the amount of chip welding,
increases abrasion resistance and
improves the chip flow.
• Sold individually.
