Abstract:

A stump grinding tool includes a rotary cutting wheel having a pair of side surfaces and an outer peripheral surface. Cutting assemblies are mounted on the cutting wheel, each cutting assembly including first and second pockets disposed on respective side surfaces of the wheel. Each pocket includes a leading through-hole and a trailing through-hole aligned with respective leading end trailing through-holes of the other pocket for receiving a pair of cutting teeth. Each tooth extends through aligned through-holes of the pocket and cutting wheel in mutually opposite directions, wherein cutting elements of the teeth are disposed adjacent respective ones of the side surfaces. Each tooth is fixed by a nut threaded thereon such that each tooth and associated nut functions to clamp both of the first and second pockets against the respective side-surfaces of the cutting wheel.

Abstract:

A stump grinding device includes a wheel having an outer peripheral edge in which a plurality of recesses are formed. Disposed in each recess is a plurality of cutting units each including a block affixed to a floor of the recess, and a bit mounted in the block. Each bit includes a hard tip disposed at a front end thereof. The bits of some of the peripheral cutting units are rotatable relative to their respective blocks, with the hard tips thereof being generally pointed. The bits of others of the peripheral cutting units are non-rotatable to their respective blocks, with the hard tips thereof forming elongated cutting edges. The peripheral cutting units are spaced from leading and trailing ends of the respective recesses to provide spaces for the passage of cuttings.

Abstract:

A stump cutter includes a rotary drum, holders mounted on the drum, and cutting bits mounted in respective bores of each holder for rotation relative thereto. Each cutting bit includes a shank having a pocket formed in a front end thereof in which the cutting tip is brazed, wherein an outer lip of the shank tightly grips an outer side surface of the cutting tip with a thermal shrink fit. The cutting tip includes a circular cutting edge formed by the intersection between portions of the front surface and side surface of the cutting tip, which surface portions intersect at a ninety degree angle. The front surface of the cutting tip includes raised radial ribs spaced circumferentially therearound for inducing rotation of the cutting bit during a cutting operation.

Abstract:

A drill bit for trenchless drilling includes a bit body defining a longitudinal axis about which the drill bit is rotated during a trenchless drilling operation. Two sets of cutting teeth are mounted at a front end of the bit body, the sets disposed on opposite sides of the axis. The first and second sets are brazed into respective slots formed in the first and second side surfaces of the bit body. The slots on each side surface communicate with a common groove, wherein the groove forms a shoulder against which rear ends of the cutting teeth abut.
