At the micrometer dial or digital readout level of precision boring heads, the detail of adjustment resolution is enhanced to 0.0005mm. Backlash free adjustment of repeatable settings is provided through proprietary mechanisms. These heads are ideal for parts machined from Inconel alloys, used in aerospace engine components and medical implants, and, due to the use of carbide-tipped (1400HV hardness) cutting tools, advanced materials with up to 80% less iterative refinement compared to conventional boring heads.

Frequently Asked Questions

What sizes of holes can boring heads machine?

They accommodate hole diameters from 5mm to 500mm, with adjustable cutting edges for both manual and CNC milling/boring machines (BT, HSK interfaces).
Yes, they comply with ISO 5089 and ASME B5.48, ensuring accuracy in automotive, aerospace, and heavy machinery industries for global manufacturing compatibility.
