JOBBERS - GENERAL PURPOSE POLISHED:
(GP) This style drill is commonly called Jobbers and is of
an intermediate length. This Drill is furnished with a 118°
point; the smooth surface enhances the chip removal action. The
straight shank style is suitable for a number of applications,
materials, and can be used on a variety of equipment.

GENERAL PURPOSE TREATED: The Black-Oxide treatment increases
abrasion resistance, allows for increased chip flow, and helps
eliminate chip welding. Used for drilling cast iron and carbon
steels. |
|
HEAVY DUTY TREATED: Designed for drilling cotter pin holes
and steering knules, it is also recommended for drilling high
tensile strength steel. The heavy-duty drill is furnished with
a 135° Split Point except in sizes smaller than 1/16th in
fractional sizes and 52 in wire gauge sizes. The self-centering
split-point helps eliminate walking at the drill point to provide
more accurate drilling. The Black-Oxide treatment increases abrasion
resistance, allows for increased chip flow, and helps eliminate
chip welding. |

HIGH SPIRAL - HIGH HELIX (FAST
SPIRAL) BRIGHT: Designed for the drilling of deep holes and
has a 118° point, the high helix and open flutes allow for
chips to clear the hole easily. This drill can be used in low
tensile strength aluminum, copper, magnesium, and die casting
materials. Other materials include soft steels, free machining
brass and bronze, stainless steels, and screw machine stock.

DYNA-FLUTE (PARA-FLUTE) BRIGHT:
This drill with a 118° point is designed for rapid deep hole
drilling, with the ability to operate at faster feed rates with
reduced thrust. The special web construction with a wide parabolic
shaped flute increases the chip removal rate and allows coolant
to flow to the drill point. Due to its special geometry, wood-pecking
or periodic retracting is virtually eliminated.
