  • Patent number: 10618119
    Abstract: A cutting tool including a body, a blade, a feed shaft, and a locking member. The body defines an axis and is adapted to be received by a spindle of a power tool. The blade is removably supportable on the body and rotatable about the axis for cutting a workpiece. A feed shaft is removably supportable in the body and rotatable about the axis for engaging a workpiece, the feed shaft being mountable in the cutting tool to engage and at least partially restrain the blade. The feed shaft further includes an opening transverse to the axis. The locking member is engageable with the body and with the opening in the feed shaft. Advancement of the locking member into the opening tightens both the blade and the feed shaft to the body.

  • Patent number: 8061251
    Abstract: A power tool includes a base, a table supported by the base for pivoting movement about an axis, a coarse adjustment assembly between the base and the table, and a fine adjustment assembly between the base and the table. The fine adjustment assembly includes a rotating member supported by one of the base and the table, and an engagement surface provided by the other of the base and the table. The rotating member is selectively engageable with and rotatable along the engagement surface to finely adjust the angular position of the table relative to the base. The angular position of the table relative to the base is coarsely adjustable using the coarse adjustment assembly when the rotating member is disengaged from the engagement surface. The fine adjustment assembly disengages the coarse adjustment assembly and maintains the coarse adjustment assembly disengaged when the rotating member is engaged with the engagement surface.

  • Patent number: 7802505
    Abstract: A power tool includes a housing assembly having a housing portion and an arm extending upwardly from the housing portion. The arm has an outer surface. The power tool also includes a drive unit supported by the arm. The drive unit is operable to drive a tool element to work on a work piece. The power tool further includes a collection assembly operable to collect debris generated by the tool element working on the work piece. The collection assembly includes a collection chute assembly having an inlet and an outlet. The collection chute assembly is positionable on the arm to define, between the inlet and the outlet, a first path for debris around one side of the outer surface of the arm and a second path for debris around the other side of the outer surface of the arm.

  • Patent number: 7798041
    Abstract: A saw, such as a chop saw, a miter saw, a sliding saw, a compound miter saw, etc. In some constructions, the saw may include a miter adjustment assembly including a coarse adjustment assembly and a fine adjustment assembly. In some constructions, the saw may include a bevel adjustment assembly including a brake mechanism and a bevel detent assembly. In some constructions, the saw may include a dust collection assembly including a dust chute defining a dust both around the bevel arm. In some constructions, the saw may include a table having a top wall with a peripheral rim and a side wall depending from the top wall, and a base defining an opening in which the side wall is received and a ledge above which the rim is positioned. In some constructions, the saw may include elastomeric material covering a portion of the base, such as a bottom surface, a lateral surface, a grip surface, etc.
