Abstract: A hole saw (200) comprises a cup (202) with two cutting teeth (204) positioned on the open end of the cup (202). The two cutting teeth (204) 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 and 180 degrees. A pair of secondary gullets (207) are positioned in the cup (202) proximate to a forward cutting edge (206) of the two cutting teeth (204). The secondary gullets (207) have a predetermined depth and shape along a longitudinal axis of the cup (202) to suitably remove debris from the cup (202) during a portion of the duration of the hole cut. A plurality of raker teeth (212) may be positioned on the chords defining the spacing between the cutting teeth (204). The raker teeth (212) are disposed below the cutting teeth (204), approximately 0.030 inches to engage and move cutting debris formed by the cutting teeth (204).

Abstract translation: 孔眼（200）包括具有位于杯（202）的开口端上的两个切割齿（204）的杯（202）。 两个切割齿（204）彼此基本上直径相对，以提供介质的平衡切割接合，并且间隔约45度至180度之间的弦长度。 一对次级槽（207）位于杯子（202）中，靠近两个切割齿（204）的前切割刃（206）。 次级槽口（207）沿着杯（202）的纵向轴线具有预定的深度和形状，以在孔切割的持续时间的一部分期间适当地从杯（202）去除碎屑。 多个耙齿（212）可以定位在限定切割齿（204）之间的间隔的弦杆上。 耙齿（212）设置在切割齿（204）的下方，大约为0.030英寸，以接合和移动由切割齿（204）形成的切屑。

Abstract: A spade drill bit design in which the chip flow direction along the cutting edge (22, 24) is always in the same direction is disclosed. As the chip flow direction is governed by the chip velocity vector, the cutting edge (22, 24) is designed so that the chip velocity is always generally perpendicular to a line drawn on the main cutting edge (22, 24) to the center axis of the cutting bit.

Abstract: A hole saw having plug ejection feature. Using the arbor (20) and arbor nut (40, 140) of the present invention, the arbor of an ordinary commercially available hole saw is replaced, the arbor nut (40, 140) of the present invention being threaded into the hole saw cup (2) axial threaded inlet (6), to convert the ordinary hole saw into a plug ejecting hole saw. The arbor (20) and arbor nut (40, 140) of the plug ejecting hole saw of the present invention function as the arbor of an ordinary hole saw when used to drill the desired hole, the drill turning in a clockwise direction. When the drill rotation is reversed to a counter clockwise direction and the hole saw cup (2) is held stationary, the arbor (20) of the present invention screws through the also stationary arbor nut (40, 140), thereby ejecting the plug (1) from the hole saw cup (2).

Abstract: A power outlet strip (30) having at least one receptacle (13); an element (12) for receiving power from a power source; a switch (4) coupled between the receptacle (13) and the element (12) for receiving power, which operates to control power transfer to the receptacle (13); a sliding member (7); and a safety key (6) for controlling the position of the sliding member (7). When the safety key (6) is engaged in the outlet strip (30), it positions the sliding member (7) such that the switch (4) is accessible and operable by an operator. When the safety key (6) is removed from the outlet strip (30), it positions the sliding member (7) such that the switch (4) is inoperable by the operator. The outlet strip (30) also includes a switch cover (1) for covering the switch (4). The switch cover (1) has at least one leaf spring (52) and an actuating member (54). The actuating member (54) is operative for toggling the switch (4) to an OFF position when the switch cover (1) is depressed. The leaf spring (52) is operative for maintaining the actuating member (54) above the switch (4) when no pressure is applied to the switch cover (1).

Abstract: A carbide substrate including a binder prepared to receive a cutting material such as a diamond coating thereon. The substrate is immersed in an electrolyte solution with the substrate acting as the anode thereby providing for an electro-polished substrate surface. The electro-polished substrate surface is then etched to substantially remove the binder phase of the carbide substrate, the etching being to a depth of up to about 15 microns. The resulting surface is susceptible for receiving a coating of the diamond cutting material.
