Abstract: A drill bit includes an elongated shaft having an outer surface forming plural lands and spaces between the lands forming a helical flute; a shank located at a first end of the elongated shaft, the shank configured and arranged to engage the drill bit in a tool; a head located at an opposing end of the elongated shaft from the shank, the head including a first cutting arm and a second cutting arm, the first cutting arm including a first cutting portion having a first leading cutting edge, the second cutting arm including a second cutting portion having a second leading cutting edge; and wherein the first cutting arm includes a first groove extending through the first leading cutting edge and the second arm includes a second groove extending through the second leading cutting, the first and second grooves configured to cause shorter fibers, shavings or chips.

Abstract: A circular saw blade is divided into a plurality of circumferential sections each including a number of cutting teeth provided along the circumferential edge of the saw blade. Between each pair of teeth, a gullet is formed having a depth in the radial direction of the blade. The distance between each pair of cutting teeth defines a pitch. The depth of the gullets and the pitch of successive teeth of the saw blade is different from one another.

Abstract: The present invention relates to a rake head for a lawn or garden rake having plural rows of tines. The rake head includes a support member having a first and second edge. The rake head has a first and a second row of tines to be retained such that they have a substantially equal degree and range of movement and stress in a generally upward direction. Further, a first plurality of tines attached to a substantially planar support member defines a first plane that is intersected by a second plurality of tines attached to the support member and defines a second plane. Each of the tines of the second plurality of tines extends between and adjacent the tines of the first plurality of tines outside of the second edge. A separation of the tines is provided, thus forming two substantially identical rows of raking tines.
