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
