Abstract: A masonry drill bit having an improved insert geometry, insert orientation, and interface clearance for providing improved drill speed and penetration rate. The drill bit is adapted for use in drilling masonry or other hard, brittle material. The drill bit has an axially elongated body with a leading front end portion and a rear end portion. The rear end portion is adapted to be held by a tool holder. The body has at least one spiral groove cast in its exterior surface substantially along its length. The insert is embedded in the leading end of the body, extending generally diametrically across the leading end of the body, and centered about a latitudinal plane of the insert. The geometric design of the insert, the orientation of the insert relative to the drill bit, and the interface clearance between the insert and the grooves, reduces friction and heat; resists wear, fractures, and abrasive actions of the chips; increases design life of the elements; and enhances debris elimination.

Abstract: A wood drill with a point, cutting lips at the point, a shank and a body. The body having lands defining between them flutes. The flutes have a high helix reach extending from a distance from the cutting lips toward the shank, an intermediate helix reach extending from the high helix reach toward the shank and a low helix reach extending between the intermediate reach and the shank. The drill has screw threads in a peripheral surface of the lands from a point adjacent the cutting lips a distance toward the shank less than the length of the high helix reach of the flutes.

Abstract: An improved circular saw blade is provided which has a plurality of dimples formed on the body of the blade by cold-working the blade. The dimples each include a circumferential ridge which extends above the surfaces of the blade's body. When a side load is applied to the work piece, the ridges contact the one of the walls defining the kerf being cut that is forced by the load against the blade, so that the surface of the blade's body is spaced from the wall. The dimples are formed by cold working the blade, which stiffens the blade, reducing the vibration of the blade during the cutting process. The dimples and their ridges also provide greater heat dissipation, and tend to provide a laminar flow of air over the surface of the blade, acting much as the dimples of a golf ball.

Abstract: A hole saw comprises a cup with two cutting teeth positioned on the open end of the cup. The two cutting teeth are substantially diametrically opposed to one another to provide a balanced cutting engagement of the media and are spaced apart by a chord length of between about 45 to about 180 degrees. A pair of secondary gullets are positioned in the cup proximate to a forward cutting edge of the two cutting teeth. The secondary gullets have a predetermined depth and shape along a longitudinal axis of the cup to suitably remove debris from the cup during a portion of the duration of the hole cut. A plurality of raker teeth may be positioned on the chords defining the spacing between the cutting teeth. The raker teeth are disposed below the cutting teeth, approximately 0.030 inches to engage and move cutting debris formed by the cutting teeth.
