Chicago-Latrobe 50082 Cobalt Drill Bit

This Chicago-Latrobe 50082 is a jobber-length drill bit made from cobalt steel for drilling hard metals. It measures 5/8 inch with a decimal equivalent of 0.6250. The 135-degree split point reduces walking and starts holes cleanly. It suits maintenance and fabrication tasks where tool life matters.

For metalworkers needing a single large bit.

Mechanics and fabricators drilling stainless or alloy steel will value the cobalt construction and split-point geometry. Buyers who need a range of diameters for progressive drilling should look at a set instead. The non-coolant-through design fits standard handheld and press operations. It is not suited for through-spindle coolant systems.

5/8 inch diameter with 135-degree split point

The 5/8 inch fractional size (0.6250 decimal) determines the hole this bit produces. The 135-degree split point controls how it engages the workpiece without a centre punch. Match these two figures to your drawing or tap chart before ordering. No other specification overrides this fit decision.

Questions about this item

How does the 135-degree split point affect drilling performance?

The 135-degree split point centers the bit without a pilot hole and reduces walking on hard materials, giving cleaner entry in steel and alloy work.

What shank size does the 5/8-inch jobber bit need for a secure fit?

The bit has a straight shank matching its 5/8-inch diameter, so it requires a chuck that opens to at least .6250 inch for full grip.

What is the correct way to install this cobalt bit in a three-jaw chuck?

Open the chuck wide, insert the shank fully, then tighten each jaw evenly; the common mistake is tightening one jaw first, which leaves the bit off-center and causes run-out.
