My name is Bear. Deep drilling is my speciality.

I am the deep-drilling bear known as the «Tiefbohrbär». I am renowned for the smallest, the most unique and the most multifunctional deep drillings in the world. My unique Tiefbohrbärbohren® drillings with their distinction of Quintessential Qualified Quality (QQQ®) are of such a high precision that it can only be seen with a magnifying glass.

I work my deep drilling magic to optimise your shafts and plates made from machinable materials and thus generate maximal added value:

  • Deep drillings: continuous| blind holes | on-centre| off-centre| stepped | lengthways| lateral | diagonal
  • Special drillings: truncated | sealed gas-tight | connected | threaded | finished by honing
  • Drilling diameter: 0.5 to 250 mm
  • Depth of the drilling: up to 6000 mm
  • Hole runout: < 0.1/100 mm
  • Remaining wall thickness: up to 0.12 mm 
  • Drilling tolerance: < IT 8 for deep drilling | <IT5 with honing
  • Drilling surface: N6/Ra 0.8 | < N3/Ra 0.1 with honing

Let me introduce myself (interactive paper, 24 pages)


Let the Tiefbohrbär work his deep-drilling magic!
