Precision drill for metalwork

The Cobra Carbide 56412 is an 8xD high-performance non-coolant drill with a 13.60 mm diameter. It targets machinists and maintenance teams who need deep-hole capability without external coolant delivery. The tool is supplied new and ready for use in demanding production or repair environments.

Check machine compatibility

Verify that your spindle or drill press can accept a 13.60 mm shank and provide the rigidity required for an 8xD length-to-diameter ratio. Confirm the workpiece material suits non-coolant drilling and that your setup allows adequate chip evacuation. The decimal equivalent of .5354 inches may help when matching imperial tooling charts.

Sustained deep-hole operation

The 8xD geometry maintains hole straightness and surface finish during extended cutting cycles. Non-coolant design relies on flute geometry to eject chips efficiently under continuous load. California Proposition 65 warnings indicate the presence of chemicals linked to cancer and reproductive harm, so follow shop safety procedures during prolonged use.
