A stapler capable of dispensing staples therefrom and comprising a head and a handle. The head comprises a staple dispenser configured to dispense a staple from the stapler when a compressive force is applied to the staple dispenser, and a blade carriage that carries a blade and is configured such that the blade is extendable from the head of the stapler and is retractable into the head of the stapler. The handle is attached to the head, and permits the stapler to be swung like a hammer to drive staples dispensed from the staple dispenser.

A metal cutting drill bit has a shank portion, a flute portion defining a helix angle and a tip. The tip has a primary cutting edge extending to an outer periphery of the drill bit. The primary cutting edge has a rake face defining a rake angle. The rake angle is different from the helix angle at the tip of the drill bit.

High speed metal drill bit

The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material prior to separating the continuous stock material into discrete parts, thereby enhancing the efficiency of the forming process. The present invention also provides an improved forge for forming portions of the continuous stock material into parts having a predetermined shape. The forge can be designed to provide a clearance region proximate the forward end of the ram to permit slight flexing of the forward end of the ram in a radially outward direction during forging operations. The forge can also include a lubrication system for lubricating its various components. In addition, the forge can incrementally rotate the ram after one or more parts have been forged. By repeating the incremental rotation of the ram, the forge will eventually rotate the ram a full 360&#xb0;. An improved forging die is also provided which includes a back surface having a conical medial section and a pair of conical lateral sections that are recessed relative to the medial section such that forces will principally be applied to the medial section during forging operations.

A tool includes first and second elongated members, each member having a handle portion at one end and a jaw portion at an opposite end. Intermediate portions of the members are movably coupled to one another. Movement of the handle portions opens and closes the jaw portions. Each jaw portion includes a gripping surface configured to grip a workpiece. A pair of blade members are rigidly secured to the jaw portions, each blade member having a cutting edge.

A cutting tool ( ) has a longitudinally extending shaft portion ( ) with a chucking part ( ) and a cutting head ( ). A cutting edge ( ) is formed on the cutting head ( ). The cutting edge ( ) includes at least one cutting portion. A rake surface ( ) is formed adjacent to at least one of the cutting portions ( ) with the rake face being at a rake angle in the range from about &minus;10&deg; to about 10&deg;. A clearance face ( ) is formed adjacent to the at least one cutting portion opposite the rake face ( ). The clearance face ( ) is at a clearance angle in the range from about 10&deg; to about 50&deg;. An edge radius between the rake face and the clearance face is at a radius of from about 0.0003 to about 0.0040 inch.

A cutting tool (,) has a longitudinally extending shaft portion (,) with a chucking part (,) and a cutting head (,). A cutting edge (,) is formed on the cutting head (,). The cutting edge (,) includes at least one cutting portion. A rake surface (,) is formed adjacent to at least one of the cutting portions (,) with the rake face being at a rake angle in the range from about &minus;10&deg; to about 10&deg;. A clearance face (,) is formed adjacent to the at least one cutting portion opposite the rake face (,). The clearance face (,) is at a clearance angle in the range from about 10&deg; to about 50&deg;. An edge radius between the rake face and the clearance face is at a radius of from about 0.0003 to about 0.0040 inch.

A cutting tool (500) has a longitudinally extending shaft portion (588) with a chucking part (509) and a cutting head (506). A pressed powder cutting insert (518) with a cutting edge (520) is on the cutting head (506). The cutting edge (520) includes at least one cutting portion. A rake surface (524) is formed adjacent to at least one of the cutting portions (520) with the rake face (524) being at a rake angle from about 0.degree. to 10.degree.. A clearance face (526) is formed adjacent to the at least one cutting portion opposite the rake face (524). The clearance face (526) is at a clearance angle from about 10.degree. to 50.degree.. An edge radius (540) between the rake face (524) and the clearance face (526) is at a radius of from about 0.0015 to about 0.004 inch. The edge radius 540 is formed during pressing of the powder to form the insert, thus, enabling the insert to be directly braised into the cutting head (506).

Cutting tools for drilling concrete, aggregate, masonry or the like

The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material, prior to separating the continuous stock material into a number of discrete parts. The efficiency of the forming process is enhanced since individual parts need not be individually transported and oriented during the forming operations. By not requiring that the individual parts be separately transported and oriented during the forming operations, the quality of the parts formed by the forming method and apparatus of the present invention will also be enhanced since such separate transportation and orientation of individual parts generally increases the opportunities for misalignment and contributes to poor tolerance control during the manufacturing process.
