A treatment assembly for securing a treatment member to a shaft that includes the treatment member and a female attachment member. The treatment member defines a longitudinal axis, and has a distal end and a proximal end. The proximal end includes an attachment recess defined therein. The female attachment member has a distal end, a proximal end, and a shaft recess defined in the proximal end. The female attachment member is secured in the attachment recess of the treatment member. The shaft recess is defined by an interior surface that includes a first flat surface. The interior surface includes a first detent defined therein. When the shaft is received in the shaft recess, the first flat surface is operatively engaged with a first opposing flat surface on a male attachment member and a first ball is biased into the first detent.

A tool bit holder includes an inner sleeve in which a longitudinal bore is defined in which a tool bit is receivable and a detent is engageable with the tool bit for locking the tool bit within the longitudinal bore. An outer sleeve surrounds the inner sleeve and is movable relative to the inner sleeve between a locking position, in which the detent is engaged with the tool bit for locking the tool bit within the longitudinal bore, and a release position, in which the detent may be disengaged from the tool bit to permit removal of the tool bit from the longitudinal bore. A spring is positioned between the inner sleeve and the outer sleeve. The spring biases the outer sleeve toward the locking position

A positioning cutter/collet assembly has a cutter/collet and a magnetic attracting position key. The cutter/collet has a cutter/collet key seat recessed in an external annular surface thereof. The magnetic attracting position key is mounted on and magnetically attracts the cutter/collet key seat. The magnetic attracting position key has a body having a protruding rod and a magnetic attracting portion combined with the body and magnetically attracting the cutter/collet to prevent the magnetic attracting position key from separating from the cutter/collet.

A pocket hole jig for locating pocket holes in a workpiece includes a base with a base plate and first and second side walls extending along the base plate, and a body disposed between the first and second side walls and slidable along the base in a forward direction and a rearward direction. The body includes a drill bit aperture angled downward toward the base plate. The pocket hole jig also includes a fastener configured to releasably couple the pocket hole jig to an adjacent second pocket hole jig.

A treatment assembly for securing a treatment member to a shaft that includes the treatment member and a female attachment member. The treatment member defines a longitudinal axis, and has a distal end and a proximal end. The proximal end includes an attachment recess defined therein. The female attachment member has a distal end, a proximal end, and a shaft recess defined in the proximal end. The female attachment member is secured in the attachment recess of the treatment member. The shaft recess is defined by an interior surface that includes a first flat surface. The interior surface includes a first detent defined therein. When the shaft is received in the shaft recess, the first flat surface is operatively engaged with a first opposing flat surface on a male attachment member and a first ball is biased into the first detent.

A drill press includes a main housing, a base coupled to the main housing, and a drill unit supported by the main housing for relative movement therewith. The base includes a bore formed in a top surface and a magnet to create a magnetic field for magnetically latching the base to a workpiece. The drill press further includes a holding force detection assembly having a plug and a sensor coupled to the plug to detect the magnetic field within the base. The holding force detection assembly is received within the bore formed in the top surface of the base.

A drilling machine, in particular a magnetic core drilling machine. The drilling machine having a magnetic base to detachably secure the drilling machine to a surface. A drive motor is arranged in a housing and has a rotor shaft with a rotor shaft longitudinal axis that is connected in a power-transmitting manner via a gear mechanism to a tool spindle with a spindle longitudinal axis. A tool holder is connected to the tool spindle to receive a drilling tool. The spindle longitudinal axis is aligned substantially parallel to the longitudinal axis of the rotor shaft, and the tool spindle is axially adjusted along the longitudinal axis of the spindle relative to the drive motor and the magnetic base.

A drill press includes a main housing, a drill unit supported by the main housing for relative movement therewith, a base coupled to the main housing, the base having a bore formed in a top surface thereof and a magnet to create a magnetic field for magnetically latching the base to a workpiece, and a holding force detection assembly having a plug, a sensor positioned outside the plug to detect the magnetic field within the base, the sensor emitting a variable output voltage signal in response to the detected magnetic field, and a printed circuit board received within a slot in the plug. The holding force detection assembly is received within the bore formed in the top surface of the base.

Disclosed is a tool system including a drive for driving a tool holder including an electromagnetic generator for generating electrical energy from inertial energy of the tool holder. The tool holder may be driven in rotation, wherein the electromagnetic generator comprises a rotor part, which is rotatably mounted on the tool holder, and a stator part on the tool holder cooperating with each other for generating a voltage by electromagnetic induction. Alternatively, an axially movable inertial mass can be used for utilization of an oscillating linear movement.
