A clutch brake cutter for removing a disk-shaped clutch brake from off an input shaft that couples a truck engine to a transmission includes one or more cutting tools and employs a method of clamping and axially compressing a solid or multilayer clutch brake during the cutting operation. In some examples, the clutch brake cutter first guides a drill bit radially from an outer peripheral edge to an inner peripheral edge of the clutch brake. The resulting hole has a diameter that is less than the disk thickness of the clutch brake. Next, the clutch brake cutter guides a chisel lengthwise through the predrilled hole to split the hole open. The drilling and chiseling operation is repeated at an opposite location on the clutch brake to separate the clutch into at least two pieces that can be readily removed from the input shaft without having to first remove the transmission.

The design of the vise mechanism in this Tube Notching Device increases capabilities to position the cutting tool relative to the feedstock. This device holds feedstock, centering the feedstock latitudinally and longitudinally to the cutting bit allowing cuts to be reproduced true to each other due to the design of the vise mechanism. Existing tube notching devices allow for the cutting tool to be pivoted relative to the feedstock in one axis, and have vices that only center in one axis. The effectiveness of this tube notching device is increased by the ability of the cutting tool to both translate in one direction and pivot in 2 axes relative to the feedstock, as well as have a vice that can canter feedstock horizontally and vertically. This increased adjustability allows the vise and cutting head to be closer together, which increases safety, operator comfort, and cutting bit life.

A rotary tube notching apparatus is provided that is capable of operable attachment to a powered rotational drive device. The apparatus comprises a tube support assembly defining an aperture for receiving a tube and having a clamp for securing the tube against movement in relation to the aperture. A shaft assembly is provided for receiving a cutting tool, and a carriage assembly is rotatably mounted to the shaft assembly. The carriage assembly has at least one fastener for securing the shaft assembly in relation to the aperture. The shaft assembly is selectively repositionable in relation to the aperture in an offset dimension defined by linear displacement from a central axis of the aperture, in a yaw dimension defined by a plane extending along a central axis of the aperture, and in a roll dimension defined by a cross-sectional circumference of a tube received within the aperture.

A drill and tap guide includes an elongated body having a top surface, a bottom surface, a first side, a second side, a first end, and a second end, the elongated body defining a longitudinal axis which intersects the first and second ends, and a plurality of guide holes extending perpendicularly through the elongated body between the top surface and the bottom surface, at least one of the guide holes including a central axis which intersects the longitudinal axis of the elongated body. The elongated body also includes a positioning notch formed in the bottom surface of the elongated body, where the positioning notch including two edges on opposite sides of the positing notch, the edges forming an angle with the bottom surface, and a recess between the edges, the recess being a portion of the positioning notch which is a farthest distance away from the bottom surface.
