A shaft cutting tool incorporating a scissor assembly having a first arm, a second arm, and a hinge interconnecting the arms' proximal ends; a shaft mount attached to the first arm's distal end; and a cutting wheel assembly operatively mounted within a hollow bore formed at the second arm's distal end; wherein the cutting wheel assembly includes a drive axle and rotary bearing; and wherein the drive axle extends oppositely from the cutting wheel for engagement with a portable electric drill.

According to various embodiments, a reciprocating saw drill bit is disclosed. The reciprocating saw drill bit includes a spindle with a first axis of rotation, a portion of the spindle defining a cylindrical section having a second axis, where the second axis is not parallel to the first axis. The reciprocating saw drill bit further includes a swashplate having a hole from a first surface of the swashplate to a second surface of the swashplate and a spherical portion having a center point positioned at a fixed distance normal to a centerline of the hole, the hole having an inner surface adapted to fit around an outer surface of the cylindrical section of the spindle. The reciprocating saw drill bit additionally includes a connecting rod, adapted to slide through at least one bushing, the connecting rod having a first end and a second end, the first end of the connecting rod being adapted to connect to the spherical portion of the swashplate via a ball-and-socket/slider joint hybrid, the second end adapted to connect to a removable blade.

An attachment for converting a CNC milling machine to a CNC wire saw machine. The attachment may include a gantry that may be coupled with a respective gantry of the CNC milling machine, a carriage that may be attached to and moveable with a respective carriage of the CNC milling machine. A drive pulley of the system may be coupled with and driven by a spindle of the CNC milling machine. The drive pully may drive a wire saw through an assembly of idler pulleys. A wire tension mechanism may keep the wire fully stretched. The wire tension mechanism may include a curved guide rail mounted on the gantry and a vertical guide rail mounted on the carriage. A slider that slides vertically on the vertical guide rail and follows the curved guide rail may house a tension wheel that may keep the wire at a fully stretched state.
