Abstract: A drill, such as a hammer drill, comprises a shank part adapted to be received in a tool-holder, an axially opposite drill head (13), and a conveying part. (11) interconnecting said shank part and said drill head (13). The drill head has a free end surface defining a diametrically extending main cutting edge ( 16) having a tip (17), and a pair of auxiliary cutting edges (18) extending radially in relation to the tip and defining with the main cutting edge a pair of opposite obtuse angles (180° - o) so as to define a pair of opposite sectors (20) of said free end surface. The conveying part (11) defines only two helical flutes (12) opening into the opposite obtuse angled sectors (20). In order to increase the possible drilling speed of the drill, the total cross sectional area of the flutes (12) amounts to 45 - 55 % of the total circular cross-sectional area of the conveying part (11) of the drill. An axially extending inlet portion (22) of each of the flutes (12) has an axial length (I), which is 25 - 35 % of the axial width (w) of each of the helical flutes. The pitch angle of the helical flutes (12) is 30° - 45°, preferably 35° - 40°.

Abstract: A sheet metal hole cutter has a cap plate defining a substantially circular peripheral groove and an annular shelf extending radially outwardly from the peripheral groove. An elongated band forming an approximately circular shape with opposite ends of the band contacting each other defines a base edge received within the circular peripheral groove in an abutting relationship with an inner edge of the groove. The band defines an axial depth of about 1/2 of an inch or less, and an outer diameter within the range of about 9/16 of an inch through about 6 inches. A weld region fixedly secures the base edge of the band to the cap plate. The annular shelf of the cap plate extends radially outwardly from the base edge of the band and defines a radial depth of at least approximately 1/16 of an inch in order to prevent over-feeding of the hole cutter through a work piece. A plurality of teeth are disposed along a cutting edge of the band, and each tooth defines a cutting surface extending between an outer edge and an inner edge of the tooth. Each cutting surface is oriented at an acute angle relative to the plane of the cap plate such that the outer edge of the respective tooth is spaced further away from the cap plate than the inner edge to thereby preferentially cut the work piece with the outer edge and create a substantially burr-free hole in the work piece.

Abstract: A hydraulic tube expander includes expanding jaws engageable with an interior surface of a tube to expand the tube; a source of hydraulic fluid, a valve located between the source and the expanding jaws and a single-action release actuator operatively coupled to the valve. The valve is moveable between open and closed positions. In the closed position, hydraulic fluid can pass from the source to the expanding jaws and in the open position the hydraulic fluid can pass from the expanding jaws to the source. The actuator is movable between first and second positions. In the first position the valve is in the closed position. Movement of the actuator in a direction from the first position toward the second position moves the valve into the open position.

Abstract: A recip saw blade has a blade body and a cutting edge extending along the blade body and defined by a repeating pattern of two consecutive teeth suitable for abusive cutting applications. The blade defines a relatively coarse tooth pitch. The two consecutive teeth, which may be bi-metal, include a high tooth and a relatively low tooth in comparison to the high tooth. Each high tooth and low tooth include a primary clearance surface defining a relatively shallow primary clearance angle that is about 28° or less, and a secondary clearance surface defining a relatively steep secondary clearance angle in comparison to the primary clearance angle. The primary clearance angle of the high tooth is steeper than the primary clearance angle of the low tooth, such as between about 23° and 28°, and the secondary clearance angle of the high tooth is shallower than the secondary clearance angle of the low tooth.

Abstract: A hole cutter has a substantially cylindrical blade body defining a blade body circumference, a cutting edge formed on one end of the blade body, and an axially-elongated slot formed through the substantially cylindrical blade body. The axially-elongated slot is configured to receive chips flowing from the cutting edge within the interior of the blade body and (i) into the slot, and/or (ii) through the slot, to prevent the collection of such chips within the interior of the blade body and/or at an interface between the blade body and work piece. The axially-elongated slot defines a first end adjacent to the cutting edge, a second end axially spaced further from the cutting edge, and a slot area. The hole cutter further defines a total slot area to blade body circumference ratio within the range of about 0.1 to about 0.3 depending on the size of the hole cutter.

Abstract: A coated hole cutter including an ink-based colored coating applied only to the external surface of the cylindrical blade body of the hole cutter, but not to the surfaces of a circumferentially-extending cutting edge or to the interior surface of the blade body. The ink- based color coating is an ultraviolet activated ink that cures when the coating is exposed to a specific ultraviolet light intensity and wavelength. At least the surfaces of the cutting edge and the internal surface of the blade body, which do not include the coating, have a steam tempered oxide finish that imparts a color that contrasts with the color imparted by the coating.
