3xD High Perf Non-Coolant Drill
The Cobra Carbide 56012 is a 3xD high-performance drill designed for machining operations where through-coolant supply is unavailable. It suits metalworking professionals and maintenance teams needing a rigid, short-length tool for accurate hole production in steel and alloy workpieces.
Replacing standard jobber drills
This drill upgrades from general-purpose jobber-length bits when hole depth is limited to roughly three times the diameter and coolant cannot be delivered through the tool. The jump is worth it when a shorter flute length improves rigidity and reduces deflection, giving straighter holes in tough materials without the need for a coolant-fed spindle.
Sustained load behaviour
Under continuous cutting the non-coolant design relies on external flood or mist lubrication to manage heat at the cutting edges. The 115 mm overall length keeps the tool compact, limiting vibration during extended cycles, while the 15.87 mm diameter provides a large cross-section for strength. Performance stays consistent as long as chip evacuation and external cooling are maintained.

Questions about this item
What shank diameter fits the Cobra Carbide 56012 drill?
The drill has a 15.87 mm diameter; use a collet or chuck that matches this shank size for secure holding.
How should the 115 mm drill be installed to avoid run-out?
Insert the shank fully into a clean, matched collet or three-jaw chuck and tighten evenly; the common error is leaving a gap that causes vibration.
When will the carbide cutting edges need replacement?
Replace the drill when flank wear reaches the manufacturer's limit or when hole quality degrades; solid carbide cannot be economically re-sharpened in-house.
