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
