Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

A cutting tool according to an aspect of the present disclosure includes a shank, a joint, and a cutting portion attached through the joint to the shank. The cutting portion includes a core and a surface portion. The surface portion is disposed around a central axis of the cutting portion to cover an outer circumferential surface of the core. The surface portion includes a cutting edge. The cutting edge is disposed on an outer circumferential surface of the surface portion and formed in a helical shape about the central axis. The surface portion is a composite sintered material including a hard phase formed of a plurality of diamond particles and a plurality of cubic boron nitride particles, and a binder phase forming the remainder.

A milling tool is configured from a shank part and a head with a cutting edge that is provided on the leading end of the shank part. The head comprises an expanding diameter section, the diameter of which expands gradually from the base end that contacts the shank part in the direction of the leading end, and a decreasing diameter section, the diameter of which gradually decreases from the maximum diameter section in the direction of the leading end. At least one cutting edge is provided on each of the expanding diameter section and the decreasing diameter section.

A cutting tool includes: a rake face; a flank face continuous to the rake face; and a cutting edge formed by a ridgeline between the rake face and the flank face. The cutting tool includes: a base material having a first face on a side of the rake face and a second face on a side of the flank face; and a diamond layer covering the first face and the second face. The first face includes: a first top face continuous to the second face; and a second top face continuous to the first top face and disposed such that the first top face is sandwiched between the second top face and the second face. An angle formed between the first top face and the second top face is a negative angle in a cross section perpendicular to the cutting edge.

A contoured rake face cutting tool and method of making is disclosed. A rotary cutting tool with a plurality of teeth can cause damage to a work piece during cutting. By orienting the cutting angle of the teeth relative to the rotational central axis to high shear angle such as 50 or 70 degrees, the tool creates a high compression cut which is cleaner and less damaging to the work piece. The cutting surface itself is profiled, i.e. non-planar, such as concave or convex or other non planar shape, which is preferably formed into an ultra-hard material which is supplied for use in a planar form.

A single-edged milling tool has a shaft section and a machining section. A face cutting edge is formed on a distal end of the machining section. The face cutting edge extends radially from an outside end at an outer peripheral edge to an inside end close to the axis of rotation. The face cutting edge has an outer peripheral planar portion at a constant planar distance to a reference plane extending perpendicular to the axis of rotation. An oblique portion connects the planar portion to the inside end. The oblique portion of the face cutting edge is closer to the reference plane than the planar portion. The distance of the face cutting edge from the reference plane in the oblique portion diminishes continuously starting out from the planar portion to the inside end of the face cutting edge.

The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.
