7/16 Cobalt Jobber Drill 2075
This Cleveland Golf drill bit is a 7/16 inch fractional cobalt steel tool built for high-performance drilling. The 135 degree notch point and parabolic flute design promote efficient chip removal in deep holes. It measures 5-1/2 inches overall with a 4-1/16 inch flute length and a straight 7/16 inch shank.
Suited for hard metals, not for soft materials
The cobalt construction and 135 degree point angle suit machinists drilling stainless steel, titanium or other tough alloys where heat resistance matters. The right-hand cutting direction fits standard drill presses and handheld drills. Buyers needing coolant-through capability or a reduced shank for smaller chucks should look elsewhere.
135 degree parabolic flute geometry
The defining specification is the 135 degree notch point combined with a parabolic flute profile. This geometry reduces thrust force and clears chips from deep bores more effectively than standard twist drills. The .4375 decimal equivalent and list number 2075 confirm the exact size and catalogue reference for reordering.

Questions about this item
What does the 135-degree point angle do when the drill bit is in a drill press?
The 135-degree point angle reduces walking on hard materials and improves centring when starting a hole in steel or cast iron.
How does the parabolic flute design affect chip removal during deep drilling?
Parabolic flutes have a wider, open geometry that pulls chips out of the hole more efficiently than standard flutes, reducing heat buildup in deep cuts.
Will the 7/16-inch shank fit a standard three-jaw chuck without a sleeve?
Yes, the shank diameter matches the 7/16-inch drill size, so it clamps directly in any chuck that accepts up to 1/2-inch shanks.
