A cutting tool body is configured for securing a cutting insert with a female thread. The cutting tool body includes a machining end and a tool peripheral surface which extends therefrom. The cutting tool body further includes a through, non-threaded tool coupling bore which opens out to the tool peripheral surface and a coupling screw which has a coupling screw thread. The coupling screw is being located in the tool coupling bore and configured to secure the cutting insert. The cutting tool body further includes a holding member which engages the coupling screw thread at least when the holding member is not in contact with the cutting insert.

An overpack salvage drum including a drum body and a lid. A bottom wall and side wall of the drum body cooperate to define an interior of the drum body. The lid is configured to close an open top of the drum body. The lid includes at least two independent lid threads to engage with corresponding independent drum threads provided on the drum body. The lid includes a plurality of alternating castellations having a flat inner facing side and castellations having an arcuate inner facing side, which can be interdigitated with castellations on another lid when two lids are stacked together, or can be used to lock with a drum body to rotationally secure a drum body relative to the lid when in a stacked arrangement. The lids include lugs and recesses, or rings that allow for secure stacking of the lids.

A rotary cutting blade material has an attaching structure forming portion that is to serve as an attaching portion to the shank, a cutting structure forming portion that is to serve as a cutting blade, and a joint portion. The cutting structure forming portion has a core portion and a surface portion provided on the attaching structure forming portion with the joint portion being interposed, and the surface portion covers at least a part of a surface of the core portion. The attaching structure forming portion includes a hard material including a hard component and one or two or more types of iron group elements, and the hard material has a Young's modulus of not more than 350 GPa. The core portion includes a cemented carbide material, and the surface portion includes PCD or CBN.

A coupling and a blade for a cooling system in a cutting tool includes a first member including a shank having a first end and a second end. The first end of the shank defines a first end of the first member, and a head of the first member disposed at the second end of the shank and a top of the head of the first member defines a second end of the first member. The head of the first member is frustoconical and the first member includes a longitudinal passage in the shank. A radial opening in the head of the first member is in fluid communication with the longitudinal passage.

The invention is directed to a drill system that better uses the power curve of modern machine tools. The drill system uses IC inserts to perform the major hole diameter cutting, and a central drilling system that cuts the remaining minor diameter portion of the hole, and is configured to see less cutting surface footage, due to its position from the rotating center of the tool. A connection between the drill head and a holder body secures the drill head in a manner to effectively absorb lateral drilling forces. The drill system allows for a large diameter deep hole that remains straight throughout to be drilled at higher speed and lighter feed rates thus offering a more productive tool that takes advantage of the power curves and lower thrust capabilities of modern machine tools.

A drill bushing for a drill unit. In one embodiment, the drill bushing includes a base member having an upper surface, a lower surface configured to rest on a workpiece having a pilot hole, and a retaining member that projects from the lower surface of the base member. The retaining member has a cylindrical outer diameter that fits within the pilot hole. The drill bushing further includes a drill hole that passes from the upper surface of the base member through the retaining member to provide a passage for a drill bit. The drill bushing further includes an expandable slit that passes through the base member and the retaining member to the drill hole, and an adjustment member configured to expand the expandable slit to increase the cylindrical outer diameter of the retaining member within the pilot hole.

An angle adjustment mechanism includes an angle adjustment block including first opposing side faces inclined relative to the direction along the rotation axis of the turret; first and second adjustment blocks having inclined faces that are brought into surface contact with respective first opposing side faces, and movable in a direction along the rotation axis; a depression formed in a tool holder, and accommodates the angle adjustment block with the first and second adjustment blocks; first and second adjusters that move the first and second adjustment blocks in a direction along the rotation axis of the turret; and a first positioning member conducting positioning between the turret and the tool holder, and a second positioning member conducting positioning between the turret and the angle adjustment block. This configuration provides a mechanism for attaching a tool holder to a turret which can easily conduct highly precise angle adjustment.
