HSS, Standard Helix, 135-degree split
point
• Cast Iron - Soft and Medium
• Stainless steel
HSS, Parabolic Flute design, 135-degree
split point – Effective in deep hole drill-
ing of depths 4 times the diameter of
the drill.
• Aluminum alloys
• Low to Medium Tensile Strength materials
HSS, High Helix 118-degree point – En-
gineered with a high helix angle and
wide flute for improved chip ejection.
High helix drills are often used on mate-
rials that form chips that tend to weld
together and resist being carried up the
flutes. Specially designed for drilling
deep holes.
• Aluminum
• Aluminum alloys
• Aluminum magnesium
• Aluminum bronze
• Zinc
• Low Tensile Soft Steels
HSS, Low Helix 118-degree point – Engi-
neered with a low helix angle and wide
flute to reduce grabbing on entrance
and breakthrough and to promote better
chip ejection.
• Free Machining Brass
• Plastics
• Shallow holes in Aluminum
• High Tensile Bronze
HSS, Standard Helix, 118-degree point
• Bronze Soft and Medium
• Copper
• Copper alloys
• Carbon Steel Low and Medium Alloyed
Cobalt HHS, Jobber length, 135-degree
split point – These drills are heat resis-
tant and used for drilling tough, high
tensile strength materials.
• PH stainless steel
• Titanium
• Inconel
• High temperature alloys - Cobalt base - Iron
base - Nickel Base
• Carbon Steel - low and medium alloyed
Cobalt HSS, Jobber length, wide land
Parabolic flute design, 135-degree split
point – The wide land parabolic design
provides superior performance in a
greater range of materials and applica-
tions. Especially effective in deep-hole
drilling of depths 4 times the diameter
of the drill. Flute form produces closer
tolerances due to improved chip flow.
135-degree split point reduces thrust.
• High Alloy Steels
• Titanium
• Inconel
• PH stainless
Carbide-tipped, Standard Helix, Jobber
and Taper length 118-degree point –
Features heavy-duty construction and
heat-treated body for optimum wear re-
sistance and support of the carbide tip.
Taper length is particularly advanta-
geous when length longer than a jobber
length is required.
• Hard Cast Iron
• Non-ferrous metals
• Composites
*Not recommended for drilling Steel
