HSS long series drill bits are extra-length twist drills for deep holes and hard-to-reach work — the added reach gets you through thick material and into recessed areas where a standard jobber bit is too short.
Why long series Extra overall length for depth and reach, ground from M2 high-speed steel for a durable, clean-cutting edge.
Sizes Metric, 1.0mm to 10.0mm.
Construction M2 high-speed steel with ground flutes and a round shank, long series length.
Standard Manufactured to DIN 340.
Uses Deep-hole drilling in steel, cast iron, brass, aluminium, wood and plastics, and reaching areas a jobber bit can't.
For everyday depths choose jobber-length HSS bits; for accurate hole starting see the stub series.
