Tiefbohrbär GmbH

Deep hole drilling®:

• Drilling depths up to 3000 mm from one side without repositioning
• Drilling diameters from 0.5 mm to 275 mm
• Residual wall thickness between holes up to 0.12 mm and between hole and outer diameter up to 0.5 mm
• Drilling deviation less than 0.1/100 mm
• Drilling tolerance in the range < IT8 | Honing < IT5
• Drilling surfaces in the range < N6/Ra 0.8 | Honing N3/Ra 0.1
• Smooth, stepped and/or multiple combined centric drill holes longitudinal or eccentric drill holes – longitudinal | transverse | oblique – continuous or non-continuous (blind hole)
• Bores for direct or indirect heating or cooling lines (circuits), with gas-tight closure if required
• Fitting bores for heating elements (heating cartridges)
• Through or connecting bores for cables, air, and liquid substances
• Channel bores in plastic injection molds with W-base or workpiece-specific bore base
• Sealing or connection holes with threads or for expanders

Our vision:

Tiefbohrbär aims to achieve the smallest and deepest boreholes with the thinnest residual walls, maximum precision, and a smooth surface, based on the model of biological hollow cylinders such as veins and arteries. Tiefbohrbär drill holes® offer intelligent designers unique opportunities. Your workpieces will not only be smaller and lighter, but will also save material, protect the environment, and reduce costs. This gives all Tiefbohrbär customers the opportunity to develop ideas for new applications, tackle technological changes, and anticipate the future.
