Abstract
A displaceable cutting tool shank holder, in particular for a rotary boring head threadable on a main spindle of a machine tool, having one end with a substantially H-shaped cross section provided with parallel linear tracks cooperating with linear tracks on internal projections in a member connected to the rotary boring head to thereby define guideways in which bearing balls on roller are situated. The projections are arranged on an end portion or top portion of the rotary boring head. An opposite end of the tool shank holder has a recess wherein a cutting tool shank is lodged.

An assembly for use with a rotary boring head attachable to a main spindle of a machine tool, comprising
- an elongate displaceable cutting tool shank holder having opposed first and second ends, said first end having a substantially H-shaped cross sectional shape, said second end comprising a recess for retaining a cutting tool shank,
- a member arranged in proximity to said tool shank holder, said member and said tool shank holder having parallel linear tracks arranged in connection therewith and being positioned relative to one another such that guideways are defined by said linear tracks between said tool shank holder and said member, and
- means arranged in said guideways for enabling the displacement of said tool shank holder relative to said member.
A rotary boring head for finishing bores, comprising
- an elongate displaceable cutting tool shank holder having opposed first and second ends, said first end having a substantially H-shaped cross sectional shape comprising a pair of raised portions and an indented portion arranged therebetween on both sides of a geometric axis of said H-shaped first end, said second end having a recess therein,
- a cutting tool shank for retaining a tool tip, said tool shank being lodged in said recess of said tool shank holder,
- a member arranged in the boring head and having projections extending into said indented portions of said H-shaped first end of said cutting tool shank,
- said projections on said member and said indented portions of said tool shank holder having parallel linear tracks arranged in connection therewith and being positioned relative to one another such that guideways are defined by said linear tracks between said tool shank holder and said member, and
- means arranged in said guideways for enabling the displacement of said tool shank holder relative to said member.
