27/64" Parabolic Jobbers Length Drill Bit High Speed Steel Cobalt Tialn Coated Australia
Parabolic drills feature a unique flute design that greatly enhances chip flow, coolant flow to the drill point and heat dissipation. Recommended for Deep Hole drilling greater then three diameters deep without the need to reduce rate or withdraw the drill to clear chips, {Known as pecking}. Constant heavy feed rate is recommended.
Parabolic drills have a much different flute design with special web thinning, helix angles and Land Width than standard Jobbers Drills. The flute design with a reinforced web increases drill strength and rigidity providing closer tolerance holes and higher speeds and feeds.
General Purpose drills suitable for most applications on a wide variety of materials

27/64" Parabolic Jobbers Length Drill Bit High Speed Steel Cobalt Tialn Coated Australia (Parabolic Drill Bit Jobbers Length Fractional)
Parabolic drills feature a unique flute design that greatly enhances chip flow, coolant flow to the drill point and heat dissipation. Recommended for Deep Hole drilling greater then three diameters deep without the need to reduce rate or withdraw the drill to clear chips, {Known as pecking}. Constant heavy feed rate is recommended.
Parabolic drills have a much different flute design with special web thinning, helix angles and Land Width than standard Jobbers Drills. The flute design with a reinforced web increases drill strength and rigidity providing closer tolerance holes and higher speeds and feeds.
General Purpose drills suitable for most applications on a wide variety of materials
Ground from solid High Speed Steel Blanks
Split Point drills = Self centering point eliminates "walking" and reduce thrust required
