Abstract
A tool pick assembly and a tool and block assembly are disclosed. A sleeve is positioned about the shank to allow rotation of the tool pick and also friction fit with the block. The sleeve is stepped in complement to the shape of the surface of the shank of the tool pick and the shape of the surface of the bore in the tool holder and extends substantially all of the length, optionally all of the length, of the stepped bore in the block to reduce or prevent dust and fines from entering and wearing the bore surface. When assembled, the stepped sleeve and complementarily shaped shank of the tool pick each do not extend past the rear surface of the bore to mitigate or prevent shank deformation from impact during use.
