Cobra Carbide 51584 5xD High Perf Non-Coolant Drill 5.50mm

Application focus

The Cobra Carbide 51584 is a 5xD high-performance drill designed for non-coolant operation. Its 5.50 mm diameter suits general-purpose metalworking where through-spindle coolant is unavailable. Machinists and maintenance teams use it for short-run production and repair tasks.

Build integration

The tool fits standard drill chucks and collets that accept a 5.50 mm shank. Because it runs without external coolant, it frees the machine from coolant plumbing and filtration requirements. Shops without through-spindle capability can still drill deep holes efficiently.

Sustained load behaviour

The 5xD flute length manages chip evacuation during extended cuts without coolant assistance. Heat builds more slowly than in shorter drills, reducing the risk of workpiece hardening. California Proposition 65 warnings note chemicals known to cause cancer and reproductive harm.
