Abstract: A rotatable cutting tool includes a cutting tool body with a head portion. A bolster is at least partially received in the head portion and includes a socket, a collar portion and a shank portion. The socket is formed with a conical side wall and a radius blend. A hard tip or cutting insert is at least partially received in the socket and includes a conical head portion, a collar portion and an axially rearward frustoconical portion that generally conforms to the geometry of the socket of the bolster. The shank portion of the bolster provides a narrow bottom style geometry and the axially rearward frustoconical portion of the cutting insert provides a tapered geometry that together increases the strength of a braze joint between the bolster and the base portion, thereby reducing forces and stresses transmitted to the cutting tool during a machining operation.

Abstract: A wear-resistant armored cutting tool may be provided. The wear-resistant armored cutting tool may include a tool body, a bolster, at least one wear-resistant member, and a cutting tip. The bolster may be fixedly attached to the tool body with an end of a surface of the tool body disposed adjacent the bolster. The at least one wear-resistant member may be fixedly attached to the tool body. The at least one wear-resistant member may be disposed adjacent to the end of the surface of the tool body. The cutting tip may be fixedly attached to the bolster. The bolster, the at least one wear-resistant member, and the cutting tip may each have a material hardness which is greater than that of the tool body.

Abstract: A stump cutter tooth assembly includes a stump cutter tooth held by a pocket member that includes an arcuate shoulder having one or more tabs. A stump cutter tooth is adapted to be mounted on the pocket member. The stump cutter tooth includes a tooth body having one or more recesses and an arcuate outer surface. The arcuate outer surface of the stump cutter tooth is adapted to abut against the arcuate shoulder of the pocket member to prevent unwanted movement of the stump cutter tooth relative to the pocket member during the cutting operation. The one or more recesses of the stump cutter tooth cooperate with the one or more tabs of the pocket member to provide an anti-rotation and locating feature.

Abstract: Chuck wrenches are disclosed that include a chuck engagement portion and a sleeve. The chuck engagement portion allows the chuck wrench and chuck to remain coaxial to provide stability to the chuck wrench and chuck assembly. The sleeve prevents a pinch point from being formed between the chuck wrench and the chuck. The chuck wrenches may be used in bolting operations such as mine roof support bolting.
