12.10 mm solid carbide drill with double margins for precise hole accuracy
This solid double-margin drill is built for precision hole-making in demanding materials. It suits machinists and maintenance teams who need consistent accuracy and extended tool life. The 12.10 mm diameter targets specific fastener and dowel sizes in metalworking applications.
The Cyclone Xd coating reduces friction and heat buildup during high-speed drilling. Two full-length margins improve guidance and hole straightness while stabilising the tool in cross-holes or interrupted cuts. These features combine to lower wear rates and maintain tighter tolerances over long production runs.
The fixed 12.10 mm size handles through-holes and blind holes in steel, cast iron and similar alloys at standard feeds. It is not suited for larger diameters, stepped holes or non-metallic composites that require specialised geometries. Users needing different sizes must select separate drill variants.

Resharpen when cutting edges dull or chip; the solid double-margin design maintains hole accuracy longer, but intervals depend on workpiece material and feed rates.
Heat buildup at the cutting zone typically limits sustained use; reduce feed or use coolant to avoid premature wear on the double-margin lands.
Noise and heat rise with spindle speed and material hardness; the 3X solid construction runs cooler than thinner drills, but power draw follows your machine's torque curve.
