The everyday carbide drill for holes up to three diameters deep. Faster than HSS, and it holds size.

Four flutes for high-feed finishing in hardened tool steel, with an AlTiN coating that survives the heat.

Neck relief and a four-flute core for cavities deeper than three diameters, where chip evacuation and stiffness both matter.

A fixed 0.5 mm radius corner, ground to ±0.01 mm, for production work where the radius is specified on the drawing.

Six flutes, a generous radius and a strong core for high-feed roughing strategies where the machine can take it.

Five diameters deep with coolant straight to the tip. The drill that makes deep holes routine in steel and stainless.

Eight diameters, internal coolant and a strengthened web: for the holes that normally need a gun drill and a second operation.

Six flutes and a ground H7 tolerance for holes that have to come out on size and stay there.

Straight-flute H7 reaming for through holes, at a price that makes sense for general production.

Spiral flutes push the chip ahead of the cut, so a blind hole does not get scored on the way in.
