A device for cutting a block of stone that includes a support bar including a monolithic metallic plate, and a number of fluid ports attached to the plate. The device also includes a wear bar that is secured to the monolithic metallic plate and a lower longitudinal slot, and a cutting belt positioned in the lower longitudinal slot of the wear bar and including a downward-facing cutting surface to cut the block of stone. A method of cutting the stone block is also disclosed.

A band saw kit including a band saw and an angle guide. The band saw includes at least one wheel for supporting a saw blade, a motor operable to drive the blade to cut a workpiece, a frame, and a workpiece bumper coupled to the frame. The workpiece bumper includes a slot configured to receive the blade, a first engaging surface defining a first plane, and is configured to be generally perpendicular to the blade as the blade passes through the slot. An angle guide is configured to be coupled to the workpiece bumper and includes a second engaging surface for engaging a workpiece. The second engaging surface defines a second plane. A cut angle is defined by an angle between the second plane and the first plane when the angle guide is coupled to the workpiece bumper.

A saw with a monitoring and safety system that utilizes vision and sensors designed to provide user feedback on safety and training. The saw having a wheel formed of an anodized main body with a non-anodized surface extending along the circumference of the groove of the wheel. The saw having low inertial energy design to stop the blade without mechanically grabbing the blade assuring multiple points of safety detection and triggering. The saw having an automatic guard to protect the user from slipping and hitting the blade even when the saw is not running. The saw being connected to a cloud based system that enables a safer ecosystem and cross statistic sharing of safety parameters.

A power tool system includes at least one power tool which has at least one tool support unit for supporting a tool during machining, and at least one power tool separation device which extends through the tool support unit in at least one operational state. The disclosed power tool separation device comprises at least one cutting unit and at least one guide unit for guiding the cutting unit.

A band saw kit including a band saw and an angle guide. The band saw includes at least one wheel for supporting a saw blade, a motor operable to drive the blade to cut a workpiece, a frame, and a workpiece bumper coupled to the frame. The workpiece bumper includes a slot configured to receive the blade, a first engaging surface defining a first plane, and is configured to be generally perpendicular to the blade as the blade passes through the slot. An angle guide is configured to be coupled to the workpiece bumper and includes a second engaging surface for engaging a workpiece. The second engaging surface defines a second plane. A cut angle is defined by an angle between the second plane and the first plane when the angle guide is coupled to the workpiece bumper.

A power tool system comprises (i) at least one power tool, in particular a circular saw, having at least one tool support unit for supporting a tool during machining and at least one displaceably mounted tool guiding unit, and (ii) at least one power tool separation device which is arranged on the tool guiding unit. The power tool separation device comprises at least one cutting unit and at least one guide unit for guiding the cutting unit.

An angle guide for a band saw having a guide body for coupling to the band saw and a first engaging surface of the body for engaging a workpiece during a cutting operation of the band saw. The first engaging surface defines a first plane. The angle guide also has a second surface of the body defining a second plane. The second plane is substantially non-parallel to the first plane. The angle guide also includes a tool side edge of the body for being positioned adjacent the band saw, the tool side edge defining a third plane. A cut angle is defined by an angle between the first plane and the third plane.

A sawmill feedspeed control system having a force sensor operatively coupled to a sawguide of a sawblade, the output of the force sensor being processed and supplied to a motion controller and driver for reducing or increasing feed velocity of a workpiece so as to prevent overfeed or underfeed, while minimizing deviations of the blade from a straight cut and maximizing production throughput.

A cutting machine having a first wheel pair and an opposite second wheel pair, an first vertical wheel, an opposite second vertical wheel, a first drive wheel, a second opposite drive wheel, and a single cutting blade, the first vertical and the second vertical wheels being configured to travel simultaneously and in a same horizontal direction, the first and the second wheel pairs being configured to travel simultaneously and in a same vertical direction, the first wheel pair having a first slanted wheel and the second wheel pair having a second slanted wheel, the single cutting blade being routed over all wheels such that at any moment during a travel of the single cutting blade while driven by the first and second drive wheels, a vertical blade portion extends between and can travel horizontally with the first vertical wheel and the second vertical wheel during vertical cutting and a horizontal blade portion extends between and can travel vertically with the first and second wheel pairs during horizontal cutting, wherein the slant of the first slanted wheel and the slant of the second slanted wheel prevents intersection of the horizontal blade portion and the vertical blade portion.
