摘要： A tool holder module has a tool holder and a tool holder assembly jig. The tool holder assembly jig has a horizontal supporting seat. A flange recess is formed in the top surface of the horizontal supporting seat and is configured to accommodate a flange of the tool holder. The flange recess has two clamping portions, and each clamping portion protrudes from a respective one of two opposite surfaces of the flange recess and extends linearly from an opening of the flange recess toward a bottom of the flange recess. The two clamping portions are configured to engage with the two clamping recesses to prevent the tool holder from rotating relative to the horizontal supporting seat. The tool holder is selectively mounted on one of the vertical supporting seat and the horizontal supporting seat.

摘要： An assembly comprises: a chuck, which has a tool-receiving socket, a contact surface, and a screw thread; and a cutting tool, which has a tool shaft, a mating contact surface, and a mating screw thread. In a clamped state, the mating screw thread of the cutting tool is screwed into the screw thread of the chuck, the mating contact surface of the cutting tool is seated against the contact surface of the chuck, and the tool shaft is frictionally torque-transmittingly clamped in the tool-receiving socket. The invention also relates to a chuck of this type and to a cutting tool of this type.

摘要： A power tool chuck includes a body with a central bore extending along an axis and configured to receive a tool bit, a plurality of angled passageways, and a plurality of jaws received in the passageways and moveable between an axially forward and radially inward clamping position and an axially rearward and radially outward retracted position. At least one jaw has a rear end lying in a first plane transverse to the axis. A first key drive member coupled to a tail portion of the body is configured to be engaged by a second key drive member on a power tool output shaft to non-rotationally couple the body to the output shaft. The first key drive has a forward end lying in a second plane transverse to the axis. The second plane is axially forward of the first plane when the jaws are in the retracted position.

摘要： A high-speed low runout spindle assembly is provided. The spindle assembly includes a friction drive wheel configured to be coupled to an output shaft of a motor. The friction drive wheel is configured and disposed to directly contact a shank of a bit. A set of bearings is configured to contact the shank of the bit. A bit clamp assembly includes a clamp bearing having a central through-hole dimensioned to accept a lower portion of the shank of the bit. The bit clamp assembly is configured to hold the bit in contact with the set of bearings.

摘要： A clamping shank for a tool for clamping the tool into a rotary driving clamping device is proposed. The clamping shank comprises a circular shank portion and a pentagonal shank portion adjoining the circular shank portion. Four contiguous side faces of the pentagonal shank portion each form an angle of 90° to each other in a plane perpendicular to the longitudinal axis of the clamping shank. A fifth side face of the pentagonal shank portion forms in said plane angles of greater than 90° with each of the adjacent side faces of the pentagonal shank portion.

摘要： A protective device is provided that covers a drill chuck to protect it from dust or debris that may be released when a material is being drilled. The protective device has a mixed gasket comprising two sheets with fins that in their central part have independent movement where both are perforated (female type), while the other sheet contains caps (males) that are joined for better manufacturing, wherein said males are long so that they pierce the female holes and embed themselves in a base that is located directly in the protective device, allowing its adequate fastening.

摘要： A device for transmitting a torque produced by a drill to a drill bit includes a shank and a tool fitting. The shank has a first outer conical region, a groove portion, and a second outer conical region and has first longitudinal grooves and second longitudinal grooves. The tool fitting has a basic body which has first outer rotary driving grooves, an intermediate element which has first inner rotary drivers, second inner rotary drivers, and first outer rotary drivers, and a locking device. In a connected state of the device, the first inner rotary drivers engage in the first longitudinal grooves, the second inner rotary drivers engage in the second longitudinal grooves, and the first outer rotary drivers engage in the first outer rotary driving grooves. The intermediate element has second outer rotary drivers which, in the connected state, engage in second outer rotary driving grooves of the basic body.

摘要： A textured surface in an outer surface of a tool holding section of a tool holder for increasing a surface area of the outer surface for dissipating heat from the tool holding section. The textured surface can comprise grooves around the outer surface of the tool holding section with a height and a width. Notches can be provided in sides of the grooves to further increase the surface area of the outer surface for dissipating heat from the tool holding section.

摘要： A dust-proof mechanism for chuck includes a fluid supply source, an inner space inside a chuck, and a discharge space in the chuck. A supply fluid is supplied to the inner space from the fluid supply source, and passes through the inner space as a pressurized fluid. Through the discharge space, the pressurized fluid is discharged to the outside of the chuck from the inner space.

摘要： A cutting tool comprises a shank having an insertion portion protruding from a shank main body, a head in which an insertion hole into which the insertion portion is inserted is formed, and a spacer disposed in a gap between the shank main body and the head. The insertion portion has a tapered outer circumferential surface which gradually decreases in diameter from the other side toward one side in the axial direction. The insertion hole has a tapered inner circumferential surface coming into surface contact with the tapered outer circumferential surface. A head end surface of the head which faces the other side in the axial direction comes into surface contact with a surface facing one side in the axial direction of the spacer.
