Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

The present invention provides an apparatus and method for cutting a chamfer into the edge of a material while simultaneously making another cut in the material. The chamfer provides the cut material with reduced susceptibility to top surface edge swell.

There is disclosed an adjustable flange assembly for securing a cutting tool to a shaft rotatable about an axis. The adjustable flange assembly has a support plate defining an aperture for receiving the shaft and defining a reference surface on a first side thereof. The reference surface is in abutment with the cutting tool. A securing mechanism is operatively connected to the support plate and operable for releasably securing the support plate to the shaft. A deformable plate is secured to the support plate and is in abutment against a shoulder of the shaft. Adjustment members are mounted on one of the support plate and the deformable plate and are operable to exert a force on the deformable plate to locally deform the deformable plate.

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 bearingless groove router bit includes at least one cutting element affixed to a head of the router bit and has a first end spaced from an end of connected shank connected to the head and a second end adjacent to the second end of the head. The cutting element includes a cutting edge extending along the cutting element between the first end to the second end of the cutting element. The cutting edge may include a radial side edge that projects radially inwardly relative to a central axis of the router bit and a straight side edge that extends from an end of the radial side edge outwardly relative to the central axis to minimize tear out during cutting of a groove in a work piece.
