A breakaway pole including an elongated pole body extending between a bottom end and an upper end and a base connected to the bottom end of the elongated pole body. The base includes an interior flange having at least one slot. The breakaway pole includes a breakaway clamp mounted on the at least one slot of the interior flange of the base. The breakaway clamp includes a nut and a clamp body. The clamp body has a tapered main body and two lateral breakaway flanges. The lower portion of the tapered main body is positioned within the slot of the interior flange of the base. The two lateral breakaway flanges extend laterally outward from the upper portion of the tapered main body so that the two lateral breakaway flanges contact the interior flange of the base laterally beyond the at least one slot.

A pole assembly includes an elongated tubular member having an outer periphery with a pair of grooves therein, each groove defining a concave sidewall portion and a flat sidewall portion, a cam member comprising a plate-shaped portion and a pair of arms extending from a surface of the plate-shaped portion, the cam member configured to, while the major surface is adjacent a portion of the outer periphery, be rotated to cause each arm of the pair of arms to engage a respective groove of the pair of grooves, and a mount portion comprising a body defining a cavity having a pair of elongated sidewalls configured to engage respective outer surfaces of the pair of arms while the mount portion covers the cam member and the cam member is at least partially within the cavity to prevent the pair of arms from disengaging from the pair of grooves.

A lighting pole is disclosed, which includes a hollow tube, and at least two nonintersecting walls extending over an axial length of the hollow tube to divide an interior of the hollow tube into at least three isolated chambers. At least one of the three isolated chambers defines a gap separating at least two of the isolated chambers.

A cutting bit includes a body having a front surface and a side surface, the side surface including a shoulder below the front surface and extending substantially perpendicular to a central axis of the body, and a ring that is harder than the body attached to the body at a front surface of the shoulder. Wear life of the cutting bit is enhanced by maintaining particular dimensional relationships regarding the position of the ring on the body, and the diameter of portions of the body.
