Abstract
A rotatable tool has a cylindrical shank and a compressible sleeve fitted thereon to retain the shank in the bore of a tool holder. A wear ring is positioned behind the forward cutting end of the tool and against the forward surface of the tool holder. The compressible sleeve is locked to the wear ring to prevent rotation of the wear ring with the tool. Also, the outer diameter of the wear ring is greater than the width of the forward surface of the tool holder forming an overhang, and a second tool can then be used to engage the overhang to remove the tool from the tool holder.
Claims36
A tool comprising
- a tool body having a tapered cutting end, a hardened tip at a forward end of said cutting tip, an axial shank extending rearward of said forward cutting end and a radial flange joining said axial shank to said forward cutting end,
- a compressible sleeve around said shank,
- a wear ring around said shank and adjacent of said radial flange, and
- means for locking said wear ring to said sleeve to prevent rotation of said wear ring relative to said sleeve.

In a tool having a tool body with a tapered forward cutting end, an axial shank extending rearwardly of said forward cutting end, and a rearwardly facing annular surface joining a rearward end of said forward cutting end to a forward end of said shank, a compressible sleeve around said shank, and a wear ring around said shank adjacent said annular surface, the improvement comprising
- means for locking said wear ring to said sleeve wherein said wear ring cannot rotate with respect to said sleeve.

A tool for use in a tool holder having a cylindrical bore and a forward surface, said forward surface having an outer edge defining a cylinder with a first diameter, said tool comprising
- a tool body having a tapered forward cutting end, an axial shank extending rearwardly of said forward cutting end, and a rearwardly facing annular surface joining a rearward end of said forward cutting end to a forward end of said shank,
- a compressible sleeve around said shank,
- an annular wear ring around said compressible sleeve,
- said wear ring having an outer end defining a diameter greater than said first diameter wherein said outer end of said wear ring extends beyond said forward surface of said tool holder when said shank of said tool with said sleeve and said wear ring thereon is inserted into said bore wherein a second tool can engage an overhang between said first diameter and said second diameter to remove said tool from said tool holder.

A rotatable tool comprising
- a tool body having a tapered cutting end, a hardened tip at a forward end of said cutting tip, an axial shank extending rearward of said forward cutting end and a radial flange joining said axial shank to said forward cutting end,
- a compressible sleeve around said shank,
- a wear ring around said shank and adjacent of said radial flange,
- said compressible sleeve having a forward end,
- said forward end of said compressible sleeve having a radially outwardly extending protrusion wherein said forward end is non-circular, and
- said wear ring having a non-circular central opening for receiving said non-circular forward end of said sleeve wherein said projections on said compressible sleeve will contract a surface of said non-circular central opening and prevent rotation of said wear ring with respect to said sleeve.
A tool for use in a tool holder having a cylindrical bore and a forward surface, said forward surface having a central bore, said tool comprising
- a tool body having a tapered forward cutting end, an axial shank extending rearwardly of said forward cutting end, and a rearwardly facing annular surface joining a rearward end of said forward cutting end to a forward end of said shank,
- a compressible sleeve around said shank for retaining said shank in said bore of said tool holder,
- an annular wear ring around said compressible sleeve,
- said compressible sleeve having a forward end,
- said forward end of said compressible sleeve having a radially outwardly extending protrusion wherein said forward end is non-circular, and
- said wear ring having a non-circular central opening for receiving said non-circular forward end of said sleeve wherein said projections on said compressible sleeve will contract a surface of said non-circular central opening and prevent rotation of said wear ring with respect to said sleeve.
