Frequently Asked Questions

The Ø 75 mm boring head — for what type of milling machine operation?

The Ø 75 mm boring head allows high-precision boring of variable diameter holes on horizontal and vertical milling machines. Unlike a drill bit (fixed diameter), the boring head has a micrometer-adjustable slider that allows the final hole diameter to be adjusted with a precision of 0.01 mm. Used for: precision holes (H7/h7 tolerance fits), boring bearing bushes, holes with diameters not available as standard drill bits.

The included MK 3 holder — for what type of milling machine?

The MK 3 attachment indicates the Morse taper of the milling machine spindle. Verify that your milling machine's spindle has an MK 3 attachment. If the spindle has a different taper, an extension/reduction sleeve is required. The included boring bars (Ø 12 or 18 mm depending on the model) are inserted into the head body and adjusted via the micrometer screw.
