ABSTRACT:
A cutting tool has a first cutting end, a second cutting end, a shoulder at an interface between the first cutting end and the second cutting end, and a shield removably mounted on one of the first cutting end and second cutting end. The cutting ends each have a cutting tip at a distal end, a body portion, a recess in the body portion and a retainer positioned in the recess. Cutting ends can be mirror images of each other, or may be non-mirror imaged, for example with different gage lengths, to accommodate different operating conditions. One of the cutting ends is mounted in a holder and the shield protects the retainer and recess features on the operating cutting end. A combination of a reversible cutting tool and a sleeve and/or block holder system, an apparatus for cutting, a sleeve per se and a shield per se are also disclosed.
