5xD Non-Coolant Drill 7.37 mm

The Cobra Carbide 54063 is a 5xD non-coolant drill with a 7.37 mm cutting diameter and a decimal equivalent of 0.2900. It is designed for general-purpose drilling where through-tool coolant is not available or required. The solid carbide construction provides rigidity for accurate hole placement in a range of materials.

Sustained drilling performance

Without internal coolant channels the tool relies on external flood coolant or air blast for chip evacuation and heat removal. In continuous operation the cutting edges run hotter than coolant-fed equivalents, so feed rates must be managed to avoid premature wear. Stable workholding and rigid machine spindles help maintain hole quality during extended cycles.

Practical limits of non-coolant drilling

The 5xD depth capability is reachable only when chips are cleared effectively from the flutes. Deep holes in sticky or long-chipping materials may require peck cycles to prevent packing. California Proposition 65 warnings apply because the product contains chemicals known to the state to cause cancer and reproductive harm.

Questions about this item

Does the 54063 drill generate much heat or noise when run continuously in a production shift?

As a solid-carbide cutting tool it has no motor or electronics, so heat and noise come only from the machining process itself, not from the drill body.

What shank style or holder does the 7.37 mm 54063 need to fit my existing tooling?

The drill is a straight-shank solid-carbide bit; it requires a compatible collet, hydraulic chuck or shrink-fit holder that accepts the 7.37 mm diameter.

Will the 54063 work reliably in an older CNC with lower spindle speed and less rigid tool holders?

The 5xD geometry is designed for high-performance drilling; on older machines you may need to reduce feed and speed to maintain tool life and hole quality.
