Jobber Drill #5 for Hard Metals
The Cleveland Golf Jobber Drill #5 is a cobalt steel bit built for drilling chilled cast iron, high-speed steel, high-strength alloy steel, stainless steel and tool steels. Its 135-degree notch point and parabolic flute design promote efficient chip evacuation in tough materials. The straw bronze finish identifies the high-performance cobalt grade. This tool targets machinists and maintenance crews cutting hardened alloys.
Verify Shank Fit and Machine Rigidity
Confirm your drill chuck or collet accepts a 0.2055-inch straight shank before ordering. The bit has an overall length of 3-3/4 inches and a flute length of 2-1/2 inches, so check available spindle travel and workpiece clearance. Right-hand cutting direction requires standard clockwise spindle rotation. Ensure the setup provides sufficient rigidity for cobalt tooling in hard metals.
Upgrade from General-Purpose High-Speed Steel Bits
This drill replaces standard high-speed steel jobber bits when cutting the listed hard metals where rapid wear or breakage occurs. The cobalt substrate and parabolic flutes extend tool life and improve hole quality in chilled cast iron and stainless steels. The jump is worth it when production volume or material hardness makes frequent resharpening or replacement of lesser bits costly.

Questions about this item
What comes in the box with the Cleveland Golf Jobber Drill #5 Cobalt 135° Parabolic 2075 and do I need to buy anything else?
The box contains the single cobalt steel jobber drill bit, list number 2075, with a 135° notch point and parabolic flutes. No extra accessories or coolant hardware are included.
How do I choose between the different versions or capacities of this drill bit?
This listing is for one specific size: wire gauge #5 with a .2055 inch diameter and 3-3/4 inch overall length. No other diameters or lengths are offered under this part number.
What does the 135° point angle mean when I use the bit in a real machine?
The 135° notch point reduces thrust and helps the bit self-centre in hard materials such as chilled cast iron, stainless steel and high-strength alloy steel without a pilot hole.
