FAQ

When do I need a long-length drill?

When the hole depth exceeds standard jobber flute length — for deep bores, thick assemblies and awkward access points.

Why is coolant recommended?

Long flutes create more friction; coolant keeps the edge temperature down and clears chips from deep holes.

Can these drills be private-labeled?

Yes — custom branding, packaging and bulk size-assortment programs are available.
