A system including a gantry structure; a first and a second saw head movable along at least part of the length of the gantry structure; and a first and a second lumber support also movable along corresponding lengths of the gantry structure. A controller moves the first saw head and first lumber support adjacent a first location along a board and moves the second saw head and second lumber support adjacent a second location along a board, and operates the first and second saw heads to cut first and second ends off the board. The controller then moves the saw heads and the lumber supports relative to the board to third and fourth locations and operates the first and second saw heads to cut third and fourth end pieces off. The saw heads and lumber supports optionally move together and rotate around respective vertical axes to enable angled board cuts.

A bench saw, including a support structure with a lay-on section which provides a lay-on surface, as well as a saw blade which engages through an opening of the lay-on section, so that at least a part of the saw blade is located below the lay-on section lower side, a housing arrangement which is located below the lay-on section lower side and which surrounds the part of the saw blade which is located below the lay-on section lower side, where the saw blade is pivotable together with the housing arrangement relative to the lay-on section, in order to adjust an angle between a cutting plane of the saw blade and the lay-on surface. The bench saw further includes a cover flap which covers a gap between the housing arrangement and the lay-on section lower side, the gap arising on pivoting the housing arrangement.

An object of the present disclosure is to provide a circular saw guide device enabling reliable cutting in the presence of a guide function even when having no workbench for placing a workpiece thereon. The circular saw guide device 2A includes a base member 6 having a guide end 4 on one end side in the longitudinal direction for guiding a saw blade 34 there along, a tape measure 10 provided with a scale 8 freely movable back and forth having a locking claw 8a to be hooked to an end face 30c of a square timber 30, and a handle 20. A central portion of the base member 6 in the longitudinal direction is a narrow grip section 16, and the tape measure 10 is stored in an end portion in the X2 direction of the handle 20.

A table saw includes a safety system to protect a user from injury. The safety system detects a sensed condition and rapidly moves a saw blade away from the user. The safety system includes a dual ratchet mechanism to prevent the blade from rebounding back above a work surface after an initial rapid retraction of the blade. The table saw has a swing arm that rotates to move the blade below the work surface. A first ratchet engages a first contact surface of the swing arm after rotation of the swing arm over a first range of angular displacements to prevent counter rotation of the swing arm. A second ratchet engages a second contact surface of the swing arm after rotation of the swing arm over a second range of angular displacements to prevent counter rotation of the swing arm.

Inserts for use in table saws are disclosed. One embodiment may include a mechanism to lock mechanically and affirmatively the insert in a blade opening in a table saw. The mechanism is designed so that a user can install and remove the insert without tools. The mechanism also can be designed so that the front of the insert pops up above the table when released from its locked position. The mechanism can be further designed so that the insert can be unlocked or released by a user pressing a button or tab.

A fence system for a miter saw is configured to be adjusted along a horizontal axis while remaining aligned with the support table. The fence system includes a fence body defining first and second slots and an aperture, and a fixed base including first, second, and third bores. A first bushing extends through the first slot and includes a first opening, and a second bushing extends through the second slot and includes a second opening. A first fastener extends through the first opening into the first bore to clamp the first bushing to the fixed base, a second fastener extends through the second opening into the second bore to clamp the second bushing to the fixed base, and a third fastener extends through the opening into the third bore to releasably clamp the fence body to the fixed base.

The dust proof circular saw has a main body with a rotating disc cutter blade and a cover fixed to the body to cover a blade outer radial periphery part. The body is supported by a base such that an angle of the body in the up-down and right-left directions can be adjusted at a base upper side. A further blade outer radial periphery is covered by an auxiliary cover. The auxiliary cover covers a gap between the fixed cover and the base. The auxiliary cover is moved by a mechanism relative to the body in accordance with an angle of the circular saw main body relative to the base in the up-down direction. The auxiliary cover is pivotally connected to the base, and is pivoted around a laterally tilting support shaft in the right-left direction by an interlock mechanism in accordance with a body angle in the right-left direction.

A stop unit, in particular to an angle stop, for guiding and/or for the feed of a workpiece to a saw blade of a bench saw, including a stop arm which extends in a longitudinal direction for the contact of the workpiece. The stop arm includes a main section which is manufactured from a first material and which extends over more than half the longitudinal extension of the stop arm, and at least one second end section which is arranged on an end of the main section which is located in the longitudinal direction. The second section is able to come into contact with the saw blade given an advance of the workpiece towards the saw blade, where the at least one end section is manufactured from a second material.
