    Abstract: The present invention provides rotatable cutting tools having washers with changing thicknesses. One side of the washer has a tapered surface that increases the thickness of the washer from the inner radius towards the outer radius, resulting in a thicker portion at the outer edge of the washer. The rotatable cutting tool may also have a bit with a tapered surface. The tapered surface of the bit may be structured and arranged to engage with the tapered surface of the washer. The rotatable cutting tool may also include a holder such that the assembled rotatable cutting tool includes the washer between the bit and the holder with the bit inserted into the holder and washer.

    Abstract: A tool holder is disclosed for use with a milling drum. The tool holder may have a cylindrical body defining a first end and a second end, the first end configured to be received within a tool mounting block of the milling drum, the second end configured to receive a cutting bit. A flange may be located between the first and second end with respect to an axial direction, and a first bore, with a first opening defined by the second end and extending towards the first end. A frustoconical portion may be located between the flange and the first end with respect to the axial direction and a cylindrical portion located between the flange and the first end. At least one radial opening may pass through at least the wall of the cylindrical portion to intersect or be open to the first bore.

    Abstract: A bit assembly for a cutting drum includes a sleeve and a bit. The sleeve includes shank portion, a flange positioned, and a bore extending through the flange and the shank portion. The flange includes a first end surface, a second end surface, and a sleeve outer surface extending between the first end surface and the second end surface. A portion of the sleeve outer surface positioned adjacent the first end surface defines a sleeve profile. The bit includes a cutting end, a shank, and a shoulder positioned between the cutting end and the shank. The shank is positioned within the bore, and the shoulder is positioned adjacent the first end surface of the sleeve. A bit outer surface extending between the cutting end and the shoulder. A portion of the bit outer surface positioned adjacent the shoulder defines a bit profile that corresponds to the sleeve profile.

    Abstract: A profile of a cutting tip includes a convex portion extending from a cutting end to an inflection point located at an axial and radial distance from the cutting end. A concave portion extends from the inflection point to a point at a greater radial and axial distance from the cutting end. The profiles of the generally concave portion and the generally convex portion have a first linear portion defined by a portion of a first line extending from a first point at a first radial position to a second point at a second radial position and axially spaced from the first point. A second linear portion is defined by a portion of a second line extending from a third point to a fourth point at the second radial position and at an axial distance from the second point corresponding to about half a length of the first line.
