Broaching tool with adjustable cutting blades

A broaching tool having a rotational axis, comprising tool body means for supporting cutting means including cutting plate means for performing a milling operation, an insert for mounting said cutting plate means, a recess extending substantially radially relative to said rotational axis in said tool body means for receiving said insert, first separate means for a radial adjustment of said insert relative to said rotational axis, second separate means for an axial adjustment of said insert in a direction of said rotational axis, said insert having a first radially inner insert section arranged for cooperation with said first separate radial adjustment means, and a second radially outer insert section arranged for cooperation with said second separate axial adjustment means, said cutting plate means being secured to said second radially outer insert section, wherein said first radially inner insert section is only adjustable in a radial direction independently of any exclusively axial adjustment of said second radially outer insert section, and wherein a radially outward adjustment of said first radially inner insert section moves said second radially outer insert section radially outwardly, and wherein said first radially inner insert section is secured to said tool body means by a releasable screw, and wherein said second radially outer insert section is secured to said first radially inner insert section by a further releasable screw.
