Abstract
A saw disc assembly includes a circular plate having a mounting lug defining a V-shaped lug mounting profile extending between first and second sides of a tooth mount. A cutting tooth includes a shank-less body defining a cutting profile at a cutting face of the body and a mounting profile at a mounting face of the body having a configuration for complementary engagement with the lug mounting profile. The tooth mounting profile has first and second flat surfaces engageable with the lug mounting profile so that when the tooth is mounted to the lug, the flat surfaces positively resist rotation of the tooth with respect to the lug about the fastener, while a radially inner side of the tooth extending between the cutting and mounting faces is spaced from the lug and the cutting device.

A tooth for a cutting device having a tooth mounting lug defining a V-shaped lug mounting profile extending between first and second sides of the tooth mounting lug in one of a radial direction and an axial direction of the cutting device, the tooth comprising:
- a shank-less body defining a cutting profile at a cutting face of the body and a tooth mounting profile at a mounting face of the body having a configuration for complementary engagement with the lug mounting profile, the body having a through hole extending from the cutting face to the mounting face for receiving a fastener for mounting the tooth to the lug;
- wherein the tooth mounting profile has first and second flat surfaces engagable with the lug mounting profile so that when the tooth is mounted to the lug the first and second flat surfaces positively resist rotation of the tooth with respect to the lug about the fastener while a radially inner side of the tooth extending between the cutting and mounting faces is spaced from the lug and the cutting device.
A tooth assembly for a cutting device, comprising:
- a tooth mount fixed with respect to the cutting device and defining a first mounting profile with first and second flat mount surfaces extending between first and second sides of the tooth mount in one of a radial direction and an axial direction of the cutting device;
- and
- a tooth mountable to the tooth mount and defining a second mounting profile opposite a cutting profile of the tooth, the second mounting profile having first and second flat tooth surfaces extending between first and second sides of the tooth in the direction of the cutting device along which the first and second flat mount surfaces extend;
- wherein one of the first and second mounting profiles defines a V-shaped mounting groove and the other of the first and second mounting profiles defines a mounting projection configured to inter-fit with the mounting groove such that the first and second flat mount surfaces engage the respective first and second flat tooth surfaces;
- and
- wherein a radially inner side of the tooth is spaced from the tooth mount and the cutting device.
A cutting device, comprising:
- a circular plate concentric about a rotation axis and centered on a reference plane which is perpendicular to the rotation axis, the circular plate having an outer peripheral edge defining a plurality of mounting lugs extending radially out from the outer peripheral edge and spaced apart angularly along the outer peripheral edge, the mounting lugs forming tooth mounts each defining a first mounting profile forming a V-shaped groove with first and second flat mount surfaces centered about the reference plane and extending between first and second sides of the mounting lug in one of a radial direction and an axial direction of the circular plate;
- a plurality of teeth mountable to the mounting lugs, each tooth defining a second mounting profile opposite a cutting profile of the tooth, the second mounting profile having first and second flat tooth surfaces extending between first and second sides of the tooth in the one of the radial direction and the axial direction of the circular plate and, when mounted to the tooth mount, a radially inner side of the tooth is spaced from the outer peripheral edge of the circular plate;
- and
- a plurality of fasteners coupling the teeth to the mounting lugs, each of the fasteners extending along an axis contained in the reference plane and clamping the flat tooth surfaces against the flat mount surfaces.
