A level includes a frame having a top planar surface, a bottom planar surface, and a web coupling the top planar surface to the bottom planar surface. The top planar surface and the bottom planar surface are parallel. The level further includes a vial supported by the frame. The vial has a longitudinal axis passing through a center of the vial and a body defining an interior containing a liquid and an indicator bubble. The level further includes a plurality of LEDs. Each of the LEDs has a light emitting point, and each of the plurality of LEDs is positioned adjacent an end of the vial and is oriented such that the light emitting point is positioned within the interior of the body of the vial.

Level

A level including level vial(s) having enhanced visibility are provided. The level may include a level vial including a material that is attracted to the interface or border of a globule within the level vial which improves visibility of the interface. The level may include a solid level indicator having easy to see end surfaces that are generally vertically oriented when in the level position. The end surfaces of the solid level indicator may allow the user to more easily compare the position of the solid level indicator to indicating lines formed on the level vial. The level may include a level vial including a first liquid and an immiscible second liquid forming a globule with the first material. The globule formed from the second material may improve visibility compared to a typical air bubble.

Vial with improved visibility for level

An automatic process and structural features for accurately producing levels is provided. The process enables more rapid production of levels, less operator work or error, and the ability to quantify errors and tolerances in the manufacture of the level. Coupling a level datum plane formed on the endcaps of a vial with a level datum plane of a frame ensures accurate construction of a level that can be automated and toleranced. Ensuring that the level datum plane created at the endcaps remains parallel (or at some other predesigned angle) to the measuring surfaces of the level reduces labor to manufacture the level and ensures measurement accuracy.

Two datum vial mounting system and method

A tool, such as a level, including one or more magnetic coupling device is provided. The magnetic coupling device may be a magnetic circuit including metal components surrounding a magnet, such as a permanent rare-earth magnet.

Level with magnetic coupling

A hand-held band saw has a handle for grasping the band saw, a motor, a drive wheel driven by the motor, a driven wheel and a continuous blade disposed about the drive wheel and the driven wheel. A portion of the continuous blade is positioned in a cut zone to perform a cutting operation. A workpiece guard is spaced from the portion of the continuous blade and positioned between the portion of the continuous blade and the handle for limiting movement of the workpiece after the cutting operation.

Workpiece guard and blade guard for band saw

A hand-held band saw for cutting a workpiece. The hand-held band saw includes a deck, first and second wheels coupled to the deck for receiving a continuous blade thereabout, a motor coupled to the deck for driving at least one of the first or second wheels, and a handle providing a grip for a user to hold the band saw. The band saw also includes a blade guard having a first portion adjacent the first wheel, a second portion adjacent the second wheel, and a third portion adjoining the first and second portions. A joint couples the first, second, and third portions to the deck for simultaneous movement of the first, second, and third portions with respect to the deck.

A hand-held band saw having a deck defining a front and a rear, and an opening in the front defining a cut zone. The band saw also includes a first wheel supported by a first deck portion, a second wheel supported by a second deck portion, a motor operably coupled to the first wheel, a single handle providing a single grip for a user to hold the band saw with only one hand, and a continuous blade having a cutting edge. The continuous blade includes a first portion positioned in the cut zone for performing a cutting operation and a second portion positioned outside of the cut zone. A blade guard is positioned proximate the cutting edge of the second portion of the continuous blade to substantially provide a barrier between the cutting edge and an exterior of the band saw.
