The present invention relates to a tool for measuring angles and corners and cutting trim to those angles.

A compression spring is retained in a spring retaining portion provided in a fixing cover. By a pressing portion formed in a main body cover, the compression spring can be pressed to generate a biasing force in an opening direction of the main body cover. The compression spring is retained in the spring retaining portion. Accordingly, the fixing cover and main body cover can be easily assembled.

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.

A miter saw extendable fence attachment for facilitating cutting of long pieces of wood includes a centerpiece that is complementary to a table of a miter saw. The centerpiece is configured for attachment to the table. Each of a pair of extensions comprises a support and a plate. The support is reversibly couplable to a respective opposing end of the centerpiece. The plate extends perpendicularly from a front of the support adjacent to a bottom of the support. The supports are positioned to couple to the centerpiece such that the plates are positioned coplanarly with an upper face of the table. The plates are configured to place a piece of wood for cutting with a blade of the miter saw.

Exemplary embodiments of a Smart Cut system and method for efficiently and accurately converting material length using a powered saw, such as a miter saw, are disclosed. Certain embodiments are configured such that a user of a miter saw may position a board or other material beneath the miter saw blade, and cut the material to a desired length, without any need to mark a measurement on the material prior to cutting it. It is an advantage of certain embodiments that a typical retractable tape measurement device, a portable tool that is ubiquitous in the construction industry, may be leveraged to indicate proper positioning of the material prior to cutting.

A power miter saw includes a base assembly including a frame, cavities on a bottom of the frame, two supports at two sides of the frame respectively, and two parallel sliding rods passing through one support; a table assembly including a rotatable table mounted on the frame, a miter arm secured to the rotatable table, and a fence at an edge of the rotatable table and secured to the supports; and a saw blade and motor assembly. The fence includes a central curved top, two platforms at two ends of the central curved top respectively, two shoulders each at a joining portion of the curved top and the adjacent platform, and two aligned grooved members each extending outward from a position proximate the platform. The platforms are at an elevation greater than that of the miter arm.
