A device for grinding pre-milled and hard metal-tipped teeth of saw bands, is provided. The device comprises a feed device for feeding a temporary workpiece in a timed manner, wherein the temporary workpiece is formed from a plurality of saw bands which are parallel to one another. The device further comprises a clamping device which clamps the plurality of saw bands against one another, and a grinding unit for simultaneously grinding a plurality of teeth. The grinding unit comprises a grinding wheel with a plurality of grinding profiles. A corresponding method is also provided, where the grinding unit grinds both the tooth backs and the tooth faces to final dimension in exactly one infeed movement.

There is provided a guide dresser for milling a saw guide, the guide dresser comprising first and second cutter assemblies that are slidably mounted on a rail or slide system so as to be adjustable, in operation, between an open position and a closed position. There is also provided cutter heads and methods for milling a saw guide.

A guide dresser for milling a saw guide is disclosed herein. The guide dresser includes a guide mount assembly for adjustably moving a saw guide between an upper and lower position and first and second cutter assemblies that are slidably mounted on a rail or slide system so as to be adjustable, in operation, between an open position and a closed position. Cutter heads and methods for milling a saw guide are also disclosed.

Saw blades and methods of machining saw blade tooth profiles of saw blades. The saw blades include a blade body and a plurality of teeth defined by the blade body. Each tooth includes a tooth back, a tooth tip, a tooth face, and a tooth gullet. In at least one tooth, a relief region extends toward the tooth back and separates the tooth face from the tooth gullet. The methods include supporting the saw blade with a blade support structure and advancing the saw blade with a blade advance structure. The methods also include dry-machining a finished tooth profile in a working portion of the saw blade in a single pass. The dry-machining includes dry-machining with an end mill by operatively translating the end mill relative to the saw blade and within a plane that is at least substantially perpendicular to an end mill rotational axis of the end mill.

A vise for securing a chainsaw in a fixed position for field repairs and resharpening the cutting elements on the chain of a chainsaw. The vise is one piece body of generally rectangular shape with two upwardly projecting legs spaced wide enough to accept a chainsaw bar with one leg having a threaded hole and the opposing leg has a raised area. Protruding from the body downward is a tapered tang with serrated/ridges in the tapered side tang, the vise is then pushed into a piece of wood that has a slot cut into it with a chainsaw. the push vise provides a versatile device not limiting the user to just one surface, is safe to carry on your person and is easily and quickly anchored and removed.

A multi-functional tool that is particularly useful for in-field service and maintenance of a chainsaw, the tool having a handle section and a head section, wherein the handle section includes a plurality of tubular openings adapted to receive a multiplicity of repair tools, such as a chain file, depth gauge, screwdriver, wrench tool, etc., without requiring the removal of all other tools. The head section includes a pair of spaced-apart spikes to allow the tool to be secured to a wooden structure, such as a tree stump and a clamp to secure the chainsaw while service or maintenance is performed. The multi-functional chainsaw field maintenance tool further includes a device to facilitate transport of the multi-functional tool, such as a belt clip, shoulder strap or magnetic attachment device.

A saw chain holder with a bar mounted sharpener for sharpening a chain includes a base plate and a cover plate removably attachable to the base plate. The base plate has a first base side surface, an opposite second base side surface, a groove extending into the first base side surface, and a base recess extending into the second base side surface. The cover plate has a first cover side surface and an opposite second cover side surface. The cover plate is movable into an assembled state in which the first cover side surface abuts the first base side surface, the chain is movable along the groove between the base plate and the cover plate, and the bar mounted sharpener is mounted in the base recess, bears against the second cover side surface, and is positioned over the groove.

A method and apparatus for refurbishing an oscillating multi-tool blade (10) having a serrated forward end. The blade (10) is clamped to a support surface, a new serrated end is formed by cutting away an edge portion of the serrated end, the blade (10) is moved across a cutting direction so far as tips of teeth (12) of the new serrated end will be cut away during a following renewed cut, and the renewed cut is performed.

An apparatus (100), including: a base (102) configured to retain a liquid therein; an abrasive mat (200) configured to rest on a bottom of the base and to support a saw blade in a horizontal orientation; and a blade slot (612) configured to hold the saw blade in a vertical orientation.
