Definitions
- This invention relates to cutting tools, such as circular saw blades, drill bits, router bits, dado blades and hole saws.
- the invention provides a means to allow simple and accurate control of the depth of cut of the cutting tool.
- the invention provides a means to control more easily and accurately the depth of the cut or other opening formed in a workpiece by a cutting tool.
- the invention provides a cutting tool for making a cut or other opening in a workpiece, said cutting tool comprising a cutting portion having a body and a cutting tip on said body, and a set of markings on said body to indicate the distance between said tip and each said marking, for indicating to a user the depth to which said tool has penetrated into said workpiece.
- Fig. 1 is a side view of a circular saw blade containing markings according to the invention
- Fig. 2 is a side view of a drill bit containing markings according to the invention
- Fig. 3 is a side view of another form of drill bit containing markings according to the invention.
- Fig. 4 is a side view of a router bit containing markings according to the invention.
- Fig. 5 is a side view of a dado blade containing markings according to the invention.
- Fig. 1 shows a conventional circular saw blade 10 having a body 12 and cutting teeth 14.
- the teeth 14 have tips 16.
- the body 12 contains a central hole 18 to mount the blade on a spindle in conventional manner. (For hand held saws, there is usually a diamond shaped knock-out, not shown, around the hole 18 for a worm-drive saw blade mounting.)
- the blade 12 contains four sets of concentric arcuate markings 20a, 20b, 20c and 20d which indicate the radial distance from the tip 16 of each tooth 14 to the location of the marking in question.
- the markings 20a-20d can be calibrated in inches, as shown in the drawing, or they can be calibrated in the metric system (centimeters and millimeters), as preferred. For easier viewing, adjacent markings can differ from each other, e.g. they can alternate between solid and dashed lines, or they can be of different colors.
- the markings 20a-20d primarily consist of concentric arcs, which increase in arcuate length from the center of the saw blade toward its periphery (since more room is available at the outer periphery), to facilitate viewing.
- the markings can extend in a circle entirely around the saw blade, as indicated at 22, 24, again for easier viewing. The user can interpolate between the markings (or the markings can be as fine as necessary).
- circular saw blades are often used in a manner such that they protrude through a sole plate, shown in dotted lines at 30 in Fig. 1.
- the portion 32 of the blade which protrudes past the sole plate is the portion of the blade which cuts the workpiece (diagrammatically indicated at 34).
- the portion 32 projects downwardly from the sole plate 30, while in other saws (such as table saws), the portion 32 projects upwardly from the sole plate 30 (the sole plate 30 in that case consists of the table surface of the table saw).
- some saws such as many radial arm saws, and chop saws, do not have a sole plate.
- each set of markings 20a-20d has a top 36a-36d and a bottom 38a-38d.
- the terms “top” and “bottom” refer to the orientation in which the text of the markings can be read.
- the four sets of markings 20a-20d are arranged along two diameters of the blade 10, at right angles to each other. On each diameter, one set of markings has its top adjacent the tips 16 of teeth 14 (here, markings 20a and 20d), while the other set of markings (here sets 20b and 20c) have their bottoms adjacent the tips 16 of teeth 14. In this manner, at least one set of markings will be right side up whether the blade 10 is protruding upwardly or downwardly through the sole plate 30.
- the markings 20a-20d have been shown as divided into four substantially discrete sets, this can be varied as desired.
- the entire side surface of the saw blade 10 can be marked with circular lines to indicate the depth of cut.
- the depth of cut markings described are preferably applied to both sides of the saw blade.
- the markings of the invention can also be applied to a drill bit 50 having a tip 52, a body 54 and a shank 56.
- markings 58 are shown as applied to the body 54, indicating the axial distance or depth of cut from the tip 52.
- FIG. 3 shows a spade-type drill bit 60 having a body 62.
- Fig. 4 shows a router bit 74 having a body 76 with a lower cutting edge 78 and a shank 80. Markings 82 are applied to the body 76 and shank 80 to show the axial distance or depth of cut from each marking to the bottom cutting edge 78. [0019] Fig.
- FIG. 5 shows a dado blade 86 having a body 88 which supports cutting teeth 90 (much like a saw blade), and having a mounting hole 92.
- markings 94 are applied to the side of the dado blade to indicate the radial distance or depth of cut from the marking in question to the tips of the teeth 90, for accurate control of the depth of the groove formed by the dado blade 86.
- the metal of the cutting tools shown can be marked in any desired manner.
- the metal can be etched, either mechanically, or chemically, or using an electro-chemical process.
- laser marking can be used, with or without chemicals which change the color of the marks formed by the laser (if the color is changed, this can improve contrast and legibility).
- a painted tool can be used with laser marking which burns the paint off, leaving remaining paint and burnished metal color to form contrasting markings.
- Alternative methods of marking the cutting tool include the use of decals (which however may come off in use), water jets, silkscreen printing processes, stencil marking, letterpress printing, pad printing (using epoxy ink), jet printers using ink or other appropriate liquids, dot peening to form a series of dots in the metal, or (in the case of saw blades) actual perforations in the metal.
- the markings described can be applied to various kinds of cutting tools, e.g. to hole saws.
- the tools can be used for various purposes, such as woodworking, metal working, plastics, and other materials, and even for medical surgery.
- the operator may simply sight across the base of the sole plate (or table) to the arcuate line on the blade which line indicates the desired depth of cut, and then adjust the height of the blade relative to the sole plate (or table) to this line, thus to make the correct cut.
- the operator will manually control the depth of cut so that the line indicating the desired depth of cut is located at the top of the cut, flush with the surface of the workpiece being cut, while the cut is being made.
- the operator feeds the tool into the workpiece until the line marked with the desired depth of cut is again level with the upper surface of the workpiece.
- the depth of cut lines have the added advantage of indicating the perpendicularity of the bit or hole saw to the workpiece.
