Standard HSS drill bits are suitable for mild and structural steel when used at controlled speed with cutting fluid.

They offer clean, accurate drilling for general fabrication, fixings, and workshop use. Best suited to lighter sections and occasional drilling.

For harder steels or repeated use, consider upgrading to cobalt.

Cobalt drill bits offer improved heat resistance and edge retention when drilling steel.

Made with 5% cobalt alloy, they are ideal for tougher sections, repeated drilling, and applications where standard HSS struggles. Run at low speed with steady pressure for best results.

A reliable upgrade for demanding steel work.

Designed for drilling larger diameter holes in steel with increased stability and control.

The reduced flute length improves rigidity, making blacksmith drills well suited to thicker steel and high-torque drilling. Ideal for fabrication and workshop applications where accuracy matters.

Designed for cutting larger-diameter holes in steel sheet and plate.

Best used at low speed with steady pressure and cutting fluid to reduce heat build-up. Ideal for panels, trunking, enclosures, and fabrication work requiring clean openings.
