Cleveland Golf 19/64 Cobalt Jobber Drill

This fractional-inch jobber drill is built for heavy-duty metalworking. The cobalt steel body with black oxide finish resists wear while cutting alloy, carbon, stainless and tool steels. It suits machinists and maintenance technicians who need a reliable 19/64 inch bit for production or repair tasks.

Check shank fit and machine capability

The straight shank measures 19/64 inch in diameter, so verify your chuck or collet accepts this exact size. Confirm the spindle can run right-hand cutting at appropriate speeds for cobalt tooling. Ensure the workpiece setup allows a 4xD depth-to-diameter ratio without deflection or clearance issues.

Fits into a drill press or handheld drill

The 135-degree split point centres the cut without a pilot hole, reducing setup time on manual and CNC machines. Spiral flutes evacuate chips efficiently in non-coolant-through applications. The 4-3/8 inch overall length and 1-9/16 inch flute length suit standard jobber-length tooling layouts.

Questions about this item

Does the drill bit come individually or in a set, and is a drill chuck included?

The product is a single 19/64 inch cobalt jobber drill bit with a 135-degree split point and black oxide finish. A drill chuck is not included and must be purchased separately if required.

What does the 135-degree split point mean for drilling alloy, carbon, stainless, and tool steel?

The 135-degree split point is designed for self-centering and reduced thrust when drilling hard materials such as alloy, carbon, stainless, and tool steel. It helps prevent walking on contact and improves chip evacuation in these specific applications.

How deep can I drill with the 4-3/8 inch overall length and 1-9/16 inch flute length?

The flute length of 1-9/16 inches determines the maximum effective drilling depth for chip removal. The overall length is 4-3/8 inches with a shank diameter matching the 19/64 inch drill size, suitable for standard jobber-length applications.
