    • The router table push shoe (10) of the present invention has an upwardly extending handle (11) which is angled slightly towards the operator and away from the router table fence (55). The push shoe of the present invention comes with an adjustable bottom guard (20) removably attached to the base (40), and an adjustable side guard (12) which can be removed and used as a bit height measuring tool. Both the bottom guard (20) and the side guard (12) are adjustable to enable the push shoe (10) to hold thin and narrow stock. The push shoe (10) also comes equipped with a miter bar (30). The horizontally adjustable bottom guard (20) is removably attached to the base (40) via a three wing knob (22). The push shoe also has formed in the front right corner a dovetail gauge (17) for making both male and female joints for sliding dovetail joints. All of these attachments allow the push shoe (10) to be used as a push shoe and also as a miter gauge, depth of bit height reference, a scale to check the distance from the router bit to the fence, and a gauge for making 1/2" sliding dovetail joints.

    • 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).
    • 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。
