Cobra Carbide 54080 Drill

This Cobra Carbide 54080 drill is a 5xD high-performance tool designed for non-coolant drilling applications. It features a 12.20mm cutting diameter with a decimal equivalent of .4803 inches. The product is supplied new and intended for professional machining operations.

Machinists needing 5xD depth without coolant

This drill suits machinists who require a 5xD depth capability in a non-coolant configuration for 12.20mm holes. It is not for operators who need coolant-through tooling or drilling depths beyond the 5xD ratio. Buyers requiring different diameters or flute lengths should look at other options.

12.20mm diameter decides fit

The 12.20mm diameter is the single specification that determines whether this drill fits the required hole size. The .4803 decimal equivalent confirms the precise measurement for imperial cross-reference. Verify this exact diameter matches the application before purchase.

Questions about this item

When will the 12.20 mm drill need replacement?

Replace the drill when the cutting edges show visible wear, chipping, or when hole diameter and surface finish fall outside tolerance.

What limits continuous drilling depth with the 5xD flute length?

Chip evacuation becomes the limiting factor once the hole exceeds five times the diameter; the non-coolant design relies on flute clearance alone.

How much heat builds up in the 54080 during all-day drilling?

Without through-tool coolant, heat accumulates in the cutting zone; use peck cycles and appropriate feed rates to manage temperature.
