Three systems for the destruction of the data storage portion of electronic media storage devices such as hard disk drives, solid state drives and hybrid hard drives. One system utilizes a mill cutter with which the hard drive has relative motion in the direction of the axis of the mill cutter to destroy the data storage portion. A second system utilizes a laser to physically destroy the data storage portion. The third system utilizes a chemical solvent to chemically destroy the data storage portion.

A reaming tool includes a tool body having an axially rearward shank portion and an axially forward cutting portion, the forward cutting portion having at least one peripherally arranged cutting insert. The reaming tool also includes an inlet coolant channel formed in the tool body and an inlet opening at an axially rearward end of the shank portion. An outlet coolant channel is formed in the tool body and is in fluid communication with the inlet coolant channel, wherein the outlet coolant channel defines an outlet opening proximate to the cutting insert. In one particular aspect, at least a portion of the outlet coolant channel is non-linear. A method of making a component of the reaming tool by performing a printing operation on a substrate to form the component is also provided.

A cutting tool comprising a tool body comprising a shank and a cutter opposite the shank, the body defining a length from a shank end to an end face opposite the shank end, a central axis extends along the length of the body; at least one tooth having a cutting edge, the cutting edge extending along the tooth from the shank to the end face; a flute formed adjacent the at least one tooth; at least one cooling channel formed in the tooth proximate the at least one cutting edge, the at least one cooling channel having an elongated cross sectional shape with an elliptical portion and a circular portion opposite the elliptical portion, wherein the elliptical portion is located proximate the cutting edge.

A clamping system for machine tools includes a body portion configured to be received in a holding fixture of a machine, a tool holder integrally formed with and extending longitudinally from the body portion, the tool holder having a mounting mechanism on a distal end thereof for receiving a cutting tool, at least one fluid delivery vein extending through the tool holder from the body portion to the distal end of the tool holder, and at least one outlet at the distal end of the tool holder, the at least one outlet being configured to direct a fluid from the at least one fluid delivery vein toward at least one of the cutting tool and a workpiece.

A method of priming a minimum quantity lubrication (MQL) tool includes determining a category of the tool, supplying a short-prime MQL dosage if the tool is a first category or if both a second category and lubricated within a first predetermined timeframe, and supplying a long-prime MQL dosage if the tool is the second category and has not been lubricated within the predetermined timeframe. The category is based on internal passage complexity of the tool.

The present invention provides a rigid modular holding with axial and radial compensation for multiple and universal application of all machining processes, engineering, machine building, and construction fields where ever applicable for rotary and static systems. Design of modular holding includes male and female portions (401,301) of joining parts machined to the required shape and clearances to accommodate modular locking rigidly with face butting (407, 308). Radial and axial run out adjustments is controlled by the grub screws (307, 306) and run out compensation can be achieved within micron. An Area used for clamping and designed within the area of joining parts results reduction in material and processing cost. Since, the material is not protruding out from the surface of the joining parts, esthetically looks good and convenient for designing multiple applications as it is not possible at present.

A cutting tool 1 includes a cutting edge equipped with a helically curved groove 2 at a side outer periphery in the longitudinal direction, and a coolant passage pipe 3 extended internally and communicatively connected with ejection holes 4 of coolant arranged inside the groove 2 by way of a coolant passage pipe 31 branched from the coolant passage pipe 3 extended around a rotation center axis along the longitudinal direction or along the helically curved groove.

The invention relates to a modular rotary tool, which extends along an axis of rotation (6) in the longitudinal direction and which has a carrier provided with flutes as well as a cutting head exchangeably secured on said carrier, wherein the carrier has on the end surface a coupling receiving means for receiving a coupling pin of the cutting head, wherein in the carrier, a coolant channel is formed, which terminates at a first outlet opening in the coupling receiving means, and wherein a branch channel is provided, which is spaced apart from the coupling receiving means and which opens into the coolant channel at one end and terminates at a second outlet opening in the flute at the other end.

A machining tool for deburring boreholes, which lead laterally into a recess, comprising: a shaft; a cutting head with at least one circumferential cutting blade associated with a chip groove and having a cutting edge extending, at least in sections, in an axial direction, and which can perform a cutting process by virtue of relative movement between the tool and a workpiece, and which lies on a virtual cylindrical rotation surface; and at least one cutting-blade-free and chip-groove-free surface area; at least one fluid channel closed on the cutting head side, extending through the shaft into the cutting head; and at least one branch channel with an outlet opening. The outlet opening is in a dynamic pressure active surface radially set back relative to the virtual rotation surface, and is larger than a flow cross-sectional area of the at least one branch channel at the outlet opening.
