The present disclosure is directed towards an Improved Circular Saw Blade for simultaneous and combination cutting and chamfering a workpiece comprising a modified circular saw blade configured as a primary cutter to be mounted to one end of an arbor shaft rotatable on an axis. The modified circular saw blade comprises a plurality of substantially identical slots spaced circumferentially and extending radially inward towards the center. A modified chamfer tool is then configured as a secondary cutter to be aligned and mounted coaxially behind the primary cutter on the arbor shaft. The modified chamfer tool comprises angularly disposed peripheral chamfer blades mounted in the slots of the primary cutter so as to be displaceable transversely to the longitudinal axis of the modified circular saw blade. During manufacturing operations the peripheral chamfer blades of the secondary cutter are configured to follow the path of the primary cutter for simultaneously cutting and chamfering of the workpiece to a certain desired length and angle, respectively.

A bi-directional rotation feed roller for tree processing devices preferably includes a drive wheel, a drive disc, a plurality of reinforcement rings and a plurality of reinforcement plates. The drive wheel includes a drive cylinder and a plurality of media engagement thumb nails attached to the drive cylinder. The plurality of media engagement thumb nails are preferably arranged in a plurality of rows. A side wall of the plurality of media engagement thumb nails are preferably angularly offset from a lengthwise axis of the drive plate. The drive disc is attached to the drive wheel in substantially a middle of a with thereof. The plurality of reinforcement rings are attached to an inner perimeter of the drive wheel. The plurality of reinforcement plates are attached to an inside perimeter of the drive wheel between the drive disc and one end of the drive wheel.

The present discloses is a replaceable threaded insert for mounting a knife assembly or knife holder to a chipping head. The replaceable threaded insert has a generally frustoconical shape allowing the insert to be slid in an opening of the chipping head. The inner portion of the insert is threaded. A knife holder may be positioned over the chipping head and a bolt may be inserted in an aperture of the knife holder and in the threaded inner portion of the threaded insert, thus attaching the knife holder to the chipping head.

An adjusting mechanism for a cutting tool having knife holders circumferentially interspaced and having a back surface facing a circumferential direction and a seat surface facing a radial direction. The mechanism includes a support member having fixation points securable to the cutting tool. A deformable member is sandwiched between the cutting tool and the support member. The deformable member defines an adjustable lateral reference surface facing an axial direction to be in abutment with the knife inserts. An adjustment member is mounted on one of the support member and the deformable member between the fixation points of the support member. The adjustment member is operable to exert a force on the deformable member to locally deform the deformable member from an undeformed state to a deformed state. An axial distance between the support member and the deformable member is greater in the deformed state than in the undeformed state.

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 router bit for use with a turning implement comprising a router bit body having a shank body adjacent a cutting body for forming a key hole in a work piece. The shank body has an outer surface configured to be received by the turning implement. The cutting body has a body portion that spans between a tapered head portion and a tapered end portion, the tapered end portion attached to the shank body. The tapered head portion has a plunge cutting surface that forms a first acute angle with the longitudinal axis. The shank body has a diameter that is smaller than the diameter of the tapered head portion. The tapered end portion has a diameter that varies along its length from the shank body to the tapered head portion to reduce breakage of the router bit body during use. A wing may be attached to the cutting body.

A method of forming a joint between first and second workpieces generally consisting of forming a recess in one of such workpieces, provided with at least one side wall having a serrated cross-sectional configuration with inwardly projecting, distortable segments; providing a portion in the other of such workpieces, insertable into such recess, having a cross-sectional configuration sufficient to engage and distort such segments as such portion is inserted into such recess; and inserting such of the other workpiece into such recess, causing the segments to distort and thus provide an interference fit between such workpieces.

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.

The disclosure relates to a milling tool for wood or wood-like materials, as well as a method for producing such a milling tool. A longitudinal direction, a radial direction and a rotational direction are specified by an axis of rotation of the milling tool. The milling tool includes a base body as well as at least one blade which adjoins a rake face pointing forward in the rotational direction and a flank face pointing outward in the radial direction. The blade and the rake face run in a curved manner in the longitudinal direction. The curved blade and the curved rake face are formed on a cutting plate formed separately from the base body. The cutting plate is fastened to and in particular soldered on with its flat inner surface on a flat support surface of the base body.

A T-slot router bit for simultaneously cutting a T-slot groove into a work piece and withdrawing pieces of cut work piece from the T-slot groove in a single pass. The T-slot router bit includes a shank end, a boring end opposite to the shank end, a shank that extends from the shank end and is adapted to engage with a chuck of a router, a body that extends from the shank to the boring end and defines a T-shaped configuration, a pair of helical flutes of the body that extends between the shank and the boring end, and a pair of cutting edges that extends between the shank and the boring end.
